 Exhibit 10.7 
 Employment Agreement 
 This Employment Agreement dated as of
February 7, 2008 (the “Agreement”), is made by and between Allison Transmission, Inc., a Delaware corporation (together with any successor thereto, the “Company”), and Lawrence E. Dewey (the
“Executive”) (collectively referred to as the “Parties”). 
 RECITALS 

 

	A.	It is the desire of the Company to assure itself of the services of the Executive by entering into this Agreement. 

 

	B.	The Executive and the Company mutually desire that the Executive provide services to the Company on the terms herein provided. 

AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing and of the respective covenants and agreements set forth below the Parties hereto agree
as follows: 
  

	1.	Employment. 

  

	 	(a)	General. The Company shall employ the Executive and the Executive shall enter the employ of the Company, for the period set forth in Section 1(b), in
the position set forth in Section 1(c), and upon the other terms and conditions herein provided. 

  

	 	(b)	Employment Term. The initial term of employment under this Agreement (the “Initial Term”) shall be for the period beginning on August 7,
2007 (the “Effective Date”) and ending on the fifth anniversary thereof, unless earlier terminated as provided in Section 3. On the five-year anniversary of the Effective Date and each successive anniversary of the
Effective Date, the employment term hereunder shall automatically be extended for an additional one-year period (“Extension Terms” and, collectively with the Initial Term, the “Term”) unless either Party gives notice of
non-extension to the other no later than ninety (90) days prior to the then-applicable anniversary of the Effective Date (in which case the Executive’s employment will terminate at the end of the then-applicable Term or any other date set
by the Company in accordance with Section 3(b)) and subject to earlier termination as provided in Section 3. 

  

	 	(c)	 Position and Duties. The Executive shall serve as the Chief Executive Officer of the Company with such customary responsibilities, duties and
authority as may from time to time be assigned to the Executive by the Board of Directors of the Company or its parent (collectively, the “Board”). The Executive shall report to the Board. The Executive shall devote substantially
all his working time and efforts to the business and affairs of the Company (which shall include service to 

	 	 
its affiliates, if applicable). The Executive agrees to observe and comply with the rules and policies of the Company as adopted by the Company from time to time. During the Term, it shall not be
a violation of this Agreement for the Executive to (i) serve on industry trade, civic or charitable boards or committees; (ii) deliver lectures or fulfill speaking engagements; (iii) manage his personal investments and affairs; and
(iv) serve on the board of directors of one for-profit enterprise with the Board’s prior consent, as long as such activities do not interfere with the performance of the Executive’s duties and responsibilities as an employee of the
Company. 

  

	2.	Compensation and Related Matters. 

  

	 	(a)	Annual Base Salary. During the Term, the Executive shall receive a base salary at a rate of $400,000 per annum (the “Annual Base Salary”), which
shall be paid in accordance with the customary payroll practices of the Company. Such Annual Base Salary shall be reviewed (and may be adjusted) at least annually by the Board or an authorized committee of the Board. 

 

	 	(b)	Bonus. During the Term, the Executive shall be eligible to receive an annual performance-based bonus upon the achievement of certain performance goals determined
by the Board (the “Performance Bonus”). The Performance Bonus shall have a target equal to 100% of the Annual Base Salary (the “Target Bonus”) and the Executive shall have the ability to earn more (up to 400% of
Annual Base Salary) or less than the Target Bonus depending on the achievement of performance goals for the particular year, as follows: 

  

	 	(i)	Over Performance: The amount of Performance Bonus earned by the Executive shall be increased by 12% of the Target Bonus for each percentage of performance that
exceeds the target performance goals for the year in question (rounded to the nearest percentage); provided, that the Performance Bonus earned in any one year shall not exceed 400% of Annual Base Salary. 

 

	 	(ii)	Threshold Performance: The amount of Performance Bonus earned by the Executive shall be decreased by 6.67% of the Target Bonus for every percentage of
performance that is less than the target performance goals for the year in question (rounded to the nearest percentage). 

  

	 	(iii)	 2007 Performance Target; Pro-ration. For the performance period that begins on the Effective Date and ends on December 31, 2007 (the
“Post-Closing 2007 Performance Period”), the performance target shall equal $582 million in EBITDA (subject to adjustment by the Board for extraordinary events) (the “2007 Performance Target”). The amount of the
Performance Bonus for the Post-Closing 2007 Performance Period that can be earned by the Executive shall depend on actual EBITDA for the Company’s business for 2007 compared to the 2007 Performance Target

  
 2 

	 	 
(as calculated pursuant to subsections (b)(i) and b(ii)) and shall be pro-rated by multiplying the annualized performance bonus amount by 5/12. 

 

	 	(iv)	Examples. The following examples are for illustrative purposes only and are based on a target performance goal of $15,000,000 EBITDA for the year in question
(except as provided in clause (D) below): 

 (A) Target Bonus. If the actual
performance for the year is $15,000,000 of EBITDA, then the Executive is entitled to receive a $400,000 bonus. 

(B) Over Achievement Bonus. If the actual performance for the year is $16,000,000 of EBITDA, then the Executive is
entitled to receive a $736,000 bonus. If the actual performance for the year is $20,000,000 of EBITDA, then the Executive is entitled to receive a $1,600,000 bonus. 

(C) Threshold Bonus. If the actual performance for the year is $14,000,000 of EBITDA, then the Executive is
entitled to receive a $213,240 bonus. 
 (D) Pro-rated Bonus. If actual performance for the
Company’s 2007 fiscal year is $582 million of EBITDA, then the Executive is entitled to receive a $166,667 ($400,000 multiplied by 5/12) bonus under the post-Effective Date bonus program. The Executive may also be entitled to a bonus for the
pre-Effective Date performance period.  
 The Performance Bonus for a particular year shall become due and payable only
if the Executive remains employed with the Company as of the January 1 following such year (the “Service Trigger Date”). If a Performance Bonus becomes due and payable for a particular year, then the Company shall pay such
Performance Bonus to the Executive on the same day that the Company pays similar bonuses to other executives of the Company, provided, however, that the Company shall in no event pay the Performance Bonus to the Executive after
March 15 of the year following the year in which the applicable Service Trigger Date occurs. 
 Notwithstanding anything to
the contrary in this Section 2(b), the Board may decide not to pay the Performance Bonus if, when the applicable Performance Bonus is otherwise due and payable to the Executive, an “Event of Default” (as defined in
the Credit Agreement) has occurred (or would have occurred) under the Credit Agreement during the applicable performance period, without giving effect to any cure available under the terms of the Credit Agreement (including, without limitation,
any Rate Based Cure or Specified Equity Contribution, as each such term is defined in the Credit Agreement) or any waiver or amendment of the Credit Agreement (preventative or otherwise) that avoids or cures such Event of Default. The
Company shall give written notice to the Executive of such occurrence as soon as reasonably practicable, which notice shall include: (i) a 

  
 3 

 
copy of the Credit Agreement; (ii) the date as of which the Company became non-compliant with the Credit Agreement; (iii) a complete statement of the reasons for the non-compliance with
the Credit Agreement; and (iv) a description of the steps (if any) being taken to become compliant with the Credit Agreement. In addition, the Board may make reasonable adjustments, up or down, to the amount of Performance Bonus payable for any
year to take into account extraordinary events, such as acquisitions, dispositions and unusual or one time earnings fluctuations. 
  

	 	(c)	Benefits. During the Term, the Executive shall be eligible to participate in employee benefit plans, programs and arrangements of the Company, as may be amended
from time to time, which are generally applicable to senior officers of the Company and its subsidiaries, which as of the time of this Agreement include the Company’s health and welfare plan and the Equity Incentive Plan of Allison Transmission
Holdings, Inc. (pursuant to the terms to be set forth in a separate award agreement). 

  

	 	(d)	Vacation. During the Term, the Executive shall be entitled to paid vacation in accordance with the Company’s vacation policy, as it may be amended from time
to time; provided, however, the Executive shall be entitled to no less than five (5) weeks of paid vacation each calendar year. Any vacation shall be taken at the reasonable and mutual convenience of the Company and the Executive.

  

	 	(e)	Expenses. During the Term, the Company shall reimburse the Executive for all reasonable travel and other business expenses incurred by him in the performance of
his duties to the Company in accordance with the Company’s expense reimbursement policy. 

  

	 	(f)	Key Person Insurance. At any time during the Term, the Company shall have the right to insure the life of the Executive for the Company’s sole benefit. The
Company shall have the right to determine the amount of insurance and the type of policy. The Executive shall reasonably cooperate with the Company in obtaining such insurance by submitting to physical examinations, by supplying all information
reasonably required by any insurance carrier, and by executing all necessary documents reasonably required by any insurance carrier. The Executive shall incur no financial obligation by executing any required document, and shall have no interest in
any such policy. 

  

	3.	Termination. 

 The
Executive’s employment hereunder may be terminated by the Company or the Executive, as applicable, without any breach of this Agreement only under the following circumstances: 

 

	 	(a)	Circumstances. 

  

	 	(i)	Death. The Executive’s employment hereunder shall terminate upon his death. 

  
 4 

	 	(ii)	Disability. If the Executive has incurred a Disability, as defined in Section 10(d), the Company may terminate the Executive’s employment.

  

	 	(iii)	Termination for Cause. The Company may terminate the Executive’s employment for Cause, as defined in Section 10(a). 

 

	 	(iv)	Termination without Cause. The Company may terminate the Executive’s employment without Cause. 

 

	 	(v)	Resignation for Good Reason. The Executive may resign his employment for Good Reason, as defined in Section 10(e). 	 

  

	 	(vi)	Resignation without Good Reason. The Executive may resign his employment without Good Reason. 

 

	 	(vii)	Non-extension of Term by the Company. The Company may give notice of non-extension to the Executive pursuant to Section 1(b).

  

	 	(viii)	Non-extension of Term by the Executive. The Executive may give notice of non-extension to the Company pursuant to Section 1(b).

  

	 	(b)	Notice of Termination. Any termination of the Executive’s employment by the Company or by the Executive under this Section 3 (other than
termination pursuant to paragraph (a)(i)) shall be communicated by a written notice to the other Party hereto indicating the specific termination provision in this Agreement relied upon, setting forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and specifying a Date of Termination, as defined in Section 10(c), which shall be at least 60 days following the date of such notice
in the event of any termination of the Executive’s employment other than a Termination for Cause and at least 45 days following the date of such notice in the event of a Termination for Cause (a “Notice of Termination”). The
failure by the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in
enforcing the Company’s rights hereunder. Similarly, the failure by Executive to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason shall not waive any right of the Executive hereunder
or preclude the Executive from asserting such fact or circumstance in enforcing Executive’s rights hereunder. 

  

	 	(c)	 Company Obligations upon Termination. Upon termination of the Executive’s employment pursuant to any of the circumstances listed in
Section 3(a), the Executive (or the Executive’s estate) shall be entitled to receive the sum of: (i) the portion of the Executive’s Annual Base Salary earned through the Date of Termination, but not yet paid to the
Executive; (ii) any bonus actually earned by the Executive in the year prior to the year in which the Date of Termination occurs, but not yet paid to the Executive; (iii) any expenses owed to the Executive

  
 5 

	 	 
under Section 2(e); (iv) any accrued vacation pay owed to the Executive pursuant to Section 2(d), and (v) any amount accrued and arising from the
Executive’s participation in, or benefits accrued under any employee benefit plans, programs or arrangements under Section 2(c), which amounts shall be payable in accordance with the terms and conditions of such employee benefit
plans, programs or arrangements. (collectively, the “Company Arrangements”). For the avoidance of doubt, upon termination of the Executive’s employment for any reason, the Executive shall not be entitled to any other payments
or benefits (including Annual Base Salary) except as specifically provided for in this Section 3(c) or Section 4. 

  

	4.	Severance Payments. 

  

	 	(a)	Termination for Cause, Resignation without Good Reason or upon Non-extension of Term by the Executive. If the Executive’s employment shall terminate
pursuant to Section 3(a)(iii) for Cause, Section 3(a)(vi) for the Executive’s resignation without Good Reason, or pursuant to Section 3(a)(viii) due to Non-extension of the Term by the Executive, the
Executive shall not be entitled to any severance payment or benefits. 

  

	 	(b)	Termination without Cause, Resignation for Good Reason, Death, Disability or upon Non-extension of Term by the Company. If the Executive’s employment shall
terminate without Cause pursuant to Section 3(a)(iv), shall terminate due to the Executive’s resignation for Good Reason pursuant to Section 3(a)(v), as a result of Executive’s death pursuant to
Section 3(a)(i) or Disability pursuant to Section 3(a)(ii), or pursuant to Section 3(a)(vii) due to Non-extension of the Term by the Company then, subject to the Executive signing, within fifty (50) days
following delivery to the Executive, and not revoking a release of claims against the Company in substantially the form attached hereto as Exhibit A (the “Release”) and the Executive’s continued compliance with
Sections 5 and 6, the Executive shall receive: 

  

	 	(i)	A lump sum payment equal to 1.5 times the Executive’s Annual Base Salary as of the Date of Termination, payable within sixty (60) days following the Date of
Termination, but subject to Executive’s execution of the Release, provided that he has not revoked such Release; 

  

	 	(ii)	 A lump sum payment equal to 1.5 times the Executive’s Performance Bonus, which Performance Bonus will be based on the Performance Bonus that the
Executive would have earned had he remained employed through the end of the Company’s fiscal year in which the Date of Termination occurs (the “Termination Year”), but shall be calculated with reference to the performance of
the Company through the last day of the Company’s fiscal quarter that ended prior to the Date of Termination against performance goals for such Termination Year pro-rated to such date, as reasonably determined by the Board; provided,
that, if the Date of Termination occurs during the first quarter of a fiscal year, then the 

  
 6 

	 	 
Company’s performance in such first quarter will be used to determine the amount of such Performance Bonus; provided further, that if the Date of Termination occurs prior to the date
that performance goals for the Termination Year are established by the Board, then the lump sum payment shall instead equal 1.5 times the Executive’s Target Bonus; provided further, that the payment provided for under this subsection
4(b)(ii) is payable within sixty (60) days following the Date of Termination but subject to Executive’s execution of the Release, provided that he has not revoked such Release; and 

 

	 	(iii)	Reimbursement for, or direct payment to the carrier for, the premium costs under COBRA for the Executive and, where applicable, his spouse and dependents, for eighteen
months following the Date of Termination, under the same or a comparable Company group medical plan to the group medical plan that Executive was participating in as of the Date of Termination; provided that if the same or comparable Company group
medical plan is, at any time during such eighteen month period, not available generally to senior officers of the Company, the Executive shall receive reimbursement for, or direct payment to the carrier for, the premium costs under COBRA under a
group medical plan that is available to such senior officers of the Company. 

 If the payment of any amounts under
Section 4(b)(i) or (ii) are delayed pending the Executive’s execution of the Release, as soon as reasonably practicable following the date the Release becomes effective (but in no event later than 10 days after the Release
becomes effective), the Company will pay the Executive the amounts that would have otherwise been previously paid to the Executive under Section 4(b)(i) or (ii) prior to the execution of such Release, provided that he has not
revoked such Release. For the avoidance of doubt, no payments or benefits under Sections 4(b)(i), (ii) or (iii) shall be made until the Executive has executed the Release and the required revocation period specified in the Release has
expired. 
  

	 	(c)	Survival. The expiration or termination of the Term shall not impair the rights or obligations of any Party hereto, which shall have accrued prior to such
expiration or termination. 

  

	5.	Competition. 

  

	 	(a)	 The Executive shall not, at any time during the Term and for eighteen months after the Date of Termination, directly or indirectly engage in, have any
equity interest in, interview for a potential employment or consulting relationship with or manage or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security
holder, consultant or otherwise) that engages in any business which competes with any portion of the Business (as defined below) of the Company anywhere in the world. Notwithstanding the foregoing, it shall not be a violation of this Section

  
 7 

	 	 
5(a) for the Executive to join a division or business line of a commercial enterprise, other than any Specified Entity, with multiple divisions or business lines if such division or business line
is not competitive with the businesses of the Company and its subsidiaries, provided that the Executive performs services solely for such non-competitive division or business line, and performs no functions on behalf of (and has no involvement with
or direct or indirect responsibilities with respect to) businesses competitive with the Business of the Company anywhere in the world. Nothing herein shall prohibit the Executive from being a passive owner of not more than 4.9% of the outstanding
equity interest in any entity, other than any Specified Entity, which is publicly traded, so long as the Executive has no active participation in the business of such entity. 

 

	 	(b)	The Executive shall not, at any time during the Term and for eighteen months after the Date of Termination, directly or indirectly, recruit or otherwise solicit or
induce any employee, customer, subscriber or supplier of the Company (i) to terminate its employment or arrangement with the Company, or (ii) to otherwise change its relationship with the Company. 

 

	 	(c)	In the event the terms of this Section 5 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too
great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum
geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action. 

 

	 	(d)	As used in this Section 5, (i) the term “Company” shall include the Company, its subsidiaries, and Allison Transmission Holdings,
Inc., the parent of the Company, and (ii) the term “Business” shall include the manufacturing, development and sale of transmissions and the sale of replacement parts, “will-fit” parts, support equipment and
remanufactured transmissions for use in the vehicle aftermarket, as such business may be expanded or altered by the Company during the Term. 

  

	 	(e)	The Executive agrees, during the Term and following the Date of Termination, to refrain from disparaging the Company and its affiliates, including any of its services,
technologies or practices, or any of its directors, officers, agents, representatives or stockholders, either orally or in writing. The Company agrees, during the Term and following the Date of Termination, to refrain from disparaging the Executive;
provided, however, that the Company’s agreement to this non-disparagement clause shall be limited to official statements issued by the Company as an organization and statements of officers of the Company and members of the Board in their
official capacity as representatives of the Company. Nothing in this paragraph shall preclude the Executive, the Company, the members of the Board or officers of the Company from making truthful statements that are reasonably necessary to comply
with applicable law, regulation or legal process. 

  
 8 

	6.	Nondisclosure of Proprietary Information. 

  

	 	(a)	Except in connection with the faithful performance of the Executive’s duties hereunder or pursuant to Section 6(c) and (e), the Executive shall, in
perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for his benefit or the benefit of any person, firm, corporation or other entity any confidential or proprietary
information or trade secrets of or relating to the Company (including, without limitation, business plans, business strategies and methods, acquisition targets, intellectual property in the form of patents, trademarks and copyrights and applications
therefor, ideas, inventions, works, discoveries, improvements, information, documents, formulae, practices, processes, methods, developments, source code, modifications, technology, techniques, data, programs, other know-how or materials, owned,
developed or possessed by the Company, whether in tangible or intangible form, information with respect to the Company’s operations, processes, products, inventions, business practices, finances, principals, vendors, suppliers, customers,
potential customers, marketing methods, costs, prices, contractual relationships, regulatory status, prospects and compensation paid to employees or other terms of employment) (collectively, the “Confidential Information”), or deliver to
any person, firm, corporation or other entity any document, record, notebook, computer program or similar repository of or containing any such Confidential Information. The Parties hereby stipulate and agree that, as between them, any item of
Confidential Information is important, material and confidential and affects the successful conduct of the businesses of the Company (and any successor or assignee of the Company). Notwithstanding the foregoing, Confidential Information shall not
include any information that has been published in a form generally available to the public prior to the date the Executive proposes to disclose or use such information, provided, that such publishing of the Confidential Information shall not
have resulted from the Executive directly or indirectly breaching his obligations under this Section 6(a) or any other similar provision by which he is bound, or from any third-party breaching a provision similar to that found under this
Section 6(a). For the purposes of the previous sentence, Confidential Information will not be deemed to have been published or otherwise disclosed merely because individual portions of the information have been separately published, but only if
all material features comprising such information have been published in combination. 

  

	 	(b)	Upon termination of the Executive’s employment with the Company for any reason, the Executive will promptly deliver to the Company all correspondence, drawings,
manuals, letters, notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents or property concerning the Company’s customers, business plans, marketing strategies, products, property or processes.

  

	 	(c)	 The Executive may respond to a lawful and valid subpoena or other legal process but shall give the Company the earliest possible notice thereof, shall,
as much in advance of the return date as possible, make available to the Company and its 

  
 9 

	 	 
counsel the documents and other information sought and shall assist such counsel at Company’s expense in resisting or otherwise responding to such process. 

 

	 	(d)	As used in this Section 6 and Section 7, the term “Company” shall include the Company, its subsidiaries, and Allison
Transmission Holdings, Inc., the parent of the Company. 

  

	 	(e)	Nothing in this Agreement shall prohibit the Executive from (i) disclosing information and documents when required by law, subpoena or court order (subject to the
requirements of Section 6(c) above), (ii) disclosing information and documents to his attorney or tax adviser for the purpose of securing legal or tax advice, (iii) disclosing the Executive’s post-employment restrictions
in this Agreement in confidence to any potential new employer, or (iv) retaining, at any time, his personal correspondence, his personal contacts and documents related to his own personal benefits, entitlements and obligations.

  

	7.	Inventions. 

 All
rights to discoveries, inventions, improvements and innovations (including all data and records pertaining thereto) related to the business of the Company, whether or not patentable, copyrightable, registrable as a trademark, or reduced to writing,
that the Executive may discover, invent or originate during the Term, either alone or with others and whether or not during working hours or by the use of the facilities of the Company (“Inventions”), shall be the exclusive property
of the Company. The Executive shall promptly disclose all Inventions to the Company, shall execute at the request of the Company any assignments or other documents the Company may deem reasonably necessary to protect or perfect its rights therein,
and shall assist the Company, upon reasonable request and at the Company’s expense, in obtaining, defending and enforcing the Company’s rights therein. The Executive hereby appoints the Company as his attorney-in-fact to execute on his
behalf any assignments or other documents reasonably deemed necessary by the Company to protect or perfect its rights to any Inventions. 
  

	8.	Injunctive Relief. 

It is recognized and acknowledged by the Executive that a breach of the covenants contained in Sections 5, 6 and 7 will cause
irreparable damage to Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a
breach of any of the covenants contained in Sections 5, 6 and 7, in addition to any other remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief. 

 

	9.	Assignment and Successors. 

 The Company may assign its rights and obligations under this Agreement to any successor to all or substantially all of the business or the assets of the Company (by merger or otherwise), and may assign or
encumber this Agreement and its rights hereunder as security for indebtedness of the Company and its affiliates. This Agreement shall be binding upon and inure to the benefit of the Company, the Executive and their respective successors, assigns,
personnel 

  
 10 

 
and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of the Executive’s rights or obligations may be assigned or transferred
by the Executive, other than the Executive’s rights to payments hereunder, which may be transferred only by will or operation of law. Notwithstanding the foregoing, the Executive shall be entitled, to the extent permitted under applicable law
and applicable Company Arrangements, to select and change a beneficiary or beneficiaries to receive compensation hereunder following his death by giving written notice thereof to the Company. 

 

	10.	Certain Definitions. 

  

	 	(a)	Cause. The Company shall have “Cause” to terminate the Executive’s employment hereunder upon: 

 

	 	(i)	the Board’s determination that the Executive failed to substantially perform his duties as an employee of the Company (other than any such failure resulting from
the Executive’s Disability) that is reasonably expected to result in, or has resulted in, material economic damage to the Company or any of its affiliates (provided, that, to the extent such failure can be fully cured, the Company shall have
provided the Executive with at least 30 days’ notice of such failure and the Executive has not remedied the failure within the 30-day period); 

  

	 	(ii)	the Board’s determination that the Executive failed in any material respect to carry out or comply with any lawful and reasonable directive of the Board consistent
with the terms of this Agreement (provided, that, to the extent such failure can be fully cured, the Company shall have provided the Executive with at least 30 days’ notice of such failure and the Executive has not remedied the failure within
the 30-day period); 

  

	 	(iii)	the Executive’s conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or crime involving moral
turpitude; 

  

	 	(iv)	the Executive’s unlawful use (including being under the influence) or possession of illegal drugs on the Company’s (or any of its affiliate’s) premises
or while performing the Executive’s duties and responsibilities under this Agreement; or 

  

	 	(v)	the Executive’s commission of an act of fraud, embezzlement, misappropriation, willful misconduct, or breach of fiduciary duty against the Company or any of its
affiliates. 

  

	 	(b)	Credit Agreement. “Credit Agreement” shall mean the Credit Agreement among Allison Transmission Holdings, Inc., the Company, Citicorp North America,
Inc., Lehman Brothers Commercial Bank and the other parties thereto, dated as of August 7, 2007 and any successor thereto. 

  
 11 

	 	(c)	Date of Termination. “Date of Termination” shall mean (i) if the Executive’s employment is terminated by his death, the date of his death;
(ii) if the Executive’s employment is terminated pursuant to Section 3(a)(ii) – (vi) either the date indicated in the Notice of Termination or the date specified by the Company pursuant to Section 3(b),
whichever is earlier; (iii) if the Executive’s employment is terminated pursuant to Section 3(a)(vii) or Section 3(a)(viii), the expiration of the then-applicable Term. 

 

	 	(d)	Disability. “Disability” shall mean, at any time the Company or any of its affiliates sponsors a long-term disability plan for the Company’s
employees, “disability” as defined in such long-term disability plan for the purpose of determining a participant’s eligibility for benefits, provided, however, if the long-term disability plan contains multiple definitions of
disability, “Disability” shall refer to that definition of disability which, if the Executive qualified for such disability benefits, would provide coverage for the longest period of time. The determination of whether the Executive has a
Disability shall be made by the person or persons required to make disability determinations under the long-term disability plan. At any time the Company does not sponsor a long-term disability plan for its employees, Disability shall mean the
Executive’s inability to perform, with or without reasonable accommodation, the essential functions of his position hereunder for a total of three months during any six-month period as a result of incapacity due to mental or physical illness as
determined by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive’s legal representative, with such agreement as to acceptability not to be unreasonably withheld or delayed. Any refusal by the
Executive to submit to a medical examination for the purpose of determining Disability shall be deemed to constitute conclusive evidence of the Executive’s lack of a Disability. 

 

	 	(e)	Good Reason. The Executive shall have “Good Reason” to resign his employment within ninety (90) days following (i) a material diminution in
the Executive’s authorities, duties, or responsibilities, (ii) a material change in the geographic location at which the Executive must perform services, which shall not include a relocation of the Executive’s principal place of
employment to any location within a fifty (50) mile radius of the location from which the Executive served the Company immediately prior to the relocation, (iii) a material diminution in the Executive’s Annual Base Salary from the
Annual Base Salary in effect in the prior year, or (iv) a material diminution in the Executive’s Target Bonus from the Target Bonus in effect in the prior year. The Executive may not resign his employment for Good Reason unless the

of the Parties hereto to act in a fair and reasonable manner with respect to the interpretation and application of the provisions of this Agreement. 
  

	18.	Construction. 

This Agreement shall be deemed drafted equally by both the Parties. Its language shall be construed as a whole and according to its fair
meaning. Any presumption or principle that the language is to be construed against any Party shall not apply. The headings in this Agreement are only for convenience and are not intended to affect construction or interpretation. Any references to
paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. Also, unless the context clearly indicates to the contrary, (a) the plural includes the singular and

	19.	Arbitration.

arbitrator, together with other expenses of the arbitration incurred or approved by the arbitrator; and (c) arbitration may proceed in the absence of any Party if written notice (pursuant to the

  
 15 

 
JAMS’ rules and regulations) of the proceedings has been given to such Party. Each Party shall bear its own attorneys fees and expenses. The Parties agree to abide by all decisions and
awards rendered in such proceedings. Such decisions and awards rendered by the arbitrator shall be final and conclusive. All such controversies, claims or disputes shall be settled in this manner in lieu of any action at law or equity; provided,
however, that nothing in this subsection shall be construed as precluding the bringing an action for injunctive relief as provided in Section 8. 
  

	20.	Enforcement. 

 If
any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if
such illegal, invalid or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable. 
  

	21.	Withholding. 

 The
Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an
opinion of counsel if any questions as to the amount or requirement of withholding shall arise. 
  

	22.	Employee Acknowledgement. 

 The Executive acknowledges that he has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other
than those contained in writing herein, and has entered into this Agreement freely based on his own judgment. 
  

	23.	Section 409A. 

Notwithstanding anything to the contrary in this Agreement, if at the time of the Executive’s termination of employment with the
Company, the Executive is a “specified employee” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), as determined by the Company in accordance with Section 409A of the Code,
and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then
the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in the payments or benefits ultimately paid or provided to the Executive) until the date that is at least six (6) months
following the Executive’s termination of employment with the Company (or the earliest date permitted under Section 409A of the Code), whereupon the Company will pay the Executive a lump-sum amount equal to the cumulative amounts that would
have otherwise been 

  
 16 

 
previously paid to the Executive under this Agreement during the period in which such payments or benefits were deferred. Thereafter, payments will resume in accordance with this Agreement.

 Additionally, in the event that following the date hereof the Company or the Executive reasonably determines that any
compensation or benefits payable under this Agreement may be subject to Section 409A of the Code, the Company and the Executive shall work together to adopt such amendments to this Agreement or adopt other policies or procedures (including
amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (x) exempt the compensation and benefits payable under this Agreement from Section 409A of the Code
and/or preserve the intended tax treatment of the compensation and benefits provided with respect to this Agreement or (y) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance. 

 

	24.	Indemnification. 

The Company shall indemnify the Executive to the maximum extent permitted under the General Corporation Law of the State of Delaware for
acts taken within the scope of his employment. To the extent that the Company obtains coverage under a director and officer indemnification policy, the Executive will be entitled to such coverage on a basis that is no less favorable than the
coverage provided to any other officer or director of the Company.

 For and in consideration of the payments and other benefits due to Lawrence E. Dewey (the “Executive”) pursuant to the Employment Agreement, dated as of February 7, 2008, by and

employment with the Company, its affiliates and subsidiaries (collectively, with the Company, the “Affiliated Entities”), the Executive’s separation from employment with the Affiliated Entities, which the Executive now has or
may have against the Released Parties, whether known or unknown to the Executive, by reason of facts which have occurred on or prior to the date that the Executive has signed this Release. Such released claims include, without limitation, any and
all claims relating to the foregoing under federal, state or local laws pertaining to employment, including, without limitation, the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C.

any other claims against the Released Parties, including any rights and claims under the Age Discrimination in Employment Act. The Executive also understands that the Executive has a period of seven (7) days after signing this Release within
which to revoke his agreement, and that neither the Company nor any other person is obligated to make any payments or provide any other benefits to the Executive pursuant to the Employment Agreement until eight (8) days have passed since the

 20Employment and Severance Agreement - David S. Graziosi

 Exhibit 10.8 
 Employment Agreement 
 This Employment Agreement, dated as of
November 1, 2007 (the “Agreement”), is made by and between Allison Transmission, Inc., a Delaware corporation (together with any successor thereto, the “Company”), and David S. Graziosi (the
“Executive”) (collectively referred to as the “Parties”). 
 RECITALS 

 

	A.	It is the desire of the Company to assure itself of the services of the Executive by entering into this Agreement. 

 

	B.	The Executive and the Company mutually desire that the Executive provide services to the Company on the terms herein provided. 

AGREEMENT 

NOW, THEREFORE, in consideration of the foregoing and of the respective covenants and agreements set forth below the Parties hereto agree
as follows: 
  

	1.	Employment. 

  

	 	(a)	General. The Company shall employ the Executive and the Executive shall enter the employ of the Company, for the period set forth in Section 1(b), in
the position set forth in Section 1(c), and upon the other terms and conditions herein provided. 

  

	 	(b)	Employment Term. The initial term of employment under this Agreement (the “Initial Term”) shall be for the period beginning on the first day
that the Executive begins active employment with the Company (the “Effective Date”) and ending on the third anniversary thereof, unless earlier terminated as provided in Section 3. On the three-year anniversary of the
Effective Date and each successive anniversary of the Effective Date, the employment term hereunder shall automatically be extended for an additional one-year period (“Extension Terms” and, collectively with the Initial Term, the
“Term”) unless either Party gives notice of non-extension to the other no later than ninety (90) days prior to the then-applicable anniversary of the Effective Date (in which case the Executive’s employment will terminate at the
end of the then-applicable Term or any other date set by the Company in accordance with Section 3(b)) and subject to earlier termination as provided in Section 3. 

 

	 	(c)	 Position; Place of Employment and Duties. The Executive shall serve as the Chief Financial Officer of the Company with such customary
responsibilities, duties and authority as may from time to time be assigned to the Executive by the Chief Executive Officer of the Company or the Board of Directors of the Company or its parent (collectively, the “Board”). The
Executive shall report to 

	 	 
the Board and the Chief Executive Officer of the Company. The Executive’s principal place of employment shall be the Company’s headquarters in Indianapolis, Indiana. The Executive shall
devote substantially all his working time and efforts to the business and affairs of the Company (which shall include service to its affiliates, if applicable). The Executive agrees to observe and comply with the rules and policies of the Company as
adopted by the Company from time to time. During the Term, it shall not be a violation of this Agreement for the Executive to (i) serve on industry trade, civic or charitable boards or committees; (ii) deliver lectures or fulfill speaking
engagements; (iii) manage his personal investments and affairs; (iv) serve on the board of directors of one for-profit enterprise with the Board’s prior consent, as long as such activities do not interfere with the performance of the
Executive’s duties and responsibilities as an employee of the Company; and (v) respond to inquiries from Covalence Specialty Materials and its successors, Hexion Specialty Materials and its successors and General Chemical Industrial
Products and its successors as a result of obligations under severance agreements with such parties and statutory regulations governing these parties, and respond to inquiries regarding the plastics and chemicals industries from others in such
industries, as long as such activities do not interfere with the performance of your duties and responsibilities as an employee of the Company, including responsibilities regarding confidentiality and non-competition. 

 

	2.	Compensation and Related Matters. 

  

	 	(a)	Annual Base Salary. During the Term, the Executive shall receive a base salary at a rate of $350,000 per annum (the “Annual Base Salary”), which
shall be paid in accordance with the customary payroll practices of the Company. Such Annual Base Salary shall be reviewed (and may be adjusted) at least annually by the Board or an authorized committee of the Board. 

 

	 	(b)	Bonus. Beginning in 2008, during the Term the Executive shall be eligible to receive an annual performance-based bonus upon the achievement of certain
performance goals determined by the Board (the “Performance Bonus”). The Performance Bonus shall have a target equal to 75% of the Annual Base Salary (the “Target Bonus”) and the Executive shall have the ability to
earn more (up to 300% of Annual Base Salary) or less than the Target Bonus depending on the achievement of performance goals for the particular year, as follows: 

 

	 	(i)	Over Performance: The amount of Performance Bonus earned by the Executive shall be increased by 9% of the Annual Base Salary for each percentage of performance
that exceeds the target performance goals for the year in question (rounded to the nearest percentage); provided, that the Performance Bonus earned in any one year shall not exceed 300% of Annual Base Salary. 

  
 2 

	 	(ii)	Threshold Performance: The amount of Performance Bonus earned by the Executive shall be decreased by 5% of the Annual Base Salary for every percentage of
performance that is less than the target performance goals for the year in question (rounded to the nearest percentage). 

  

	 	(iii)	Examples. The following examples are for illustrative purposes only and are based on a target performance goal of $15,000,000 of EBITDA for the year in question:

 (A) Target Bonus. If the actual performance for the year is $15,000,000 of EBITDA, then
the Executive is entitled to receive a $262,500 bonus. 
 (B) Over Performance Bonus. If the actual
performance for the year is $16,000,000 of EBITDA, then the Executive is entitled to receive a $483,000 bonus. If the actual performance for the year is $20,000,000 of EBITDA, then the Executive is entitled to receive a $1,050,000 bonus. 

(C) Threshold Bonus. If the actual performance for the year is $14,000,000 of EBITDA, then the Executive is
entitled to receive a $140,000 bonus. 
 The Performance Bonus for a particular year shall become due and payable only if the
Executive remains employed with the Company as of the January 1 following such year (the “Service Trigger Date”). If a Performance Bonus becomes due and payable for a particular year, then the Company shall pay such Performance
Bonus to the Executive on the same day that the Company pays similar bonuses to other executives of the Company, provided, however, that the Company shall in no event pay the Performance Bonus to the Executive after
March 15 of the year following the year in which the applicable Service Trigger Date occurs. 
 Notwithstanding anything to
the contrary in this Section 2(b), the Board may decide not to pay the Performance Bonus if, when the applicable Performance Bonus is otherwise due and payable to the Executive, an “Event of Default” (as defined in
the Credit Agreement) has occurred (or would have occurred) under the Credit Agreement during the applicable performance period, without giving effect to any cure available under the terms of the Credit Agreement (including, without limitation,
any Rate Based Cure or Specified Equity Contribution, as each such term is defined in the Credit Agreement) or any waiver or amendment of the Credit Agreement (preventative or otherwise) that avoids or cures such Event of Default. The
Company shall give written notice to the Executive of such occurrence as soon as reasonably practicable, which notice shall include: (i) a copy of the Credit Agreement; (ii) the date as of which the Company became non-compliant with the
Credit Agreement; (iii) a complete statement of the reasons for the non-compliance with the Credit Agreement; and (iv) a description of the steps 

  
 3 

 
(if any) being taken to become compliant with the Credit Agreement. In addition, the Board may make reasonable adjustments, up or down, to the amount of Performance Bonus payable for any year to
take into account extraordinary events, such as acquisitions, dispositions and unusual or one time earnings fluctuations. 
 The
Executive is also eligible to receive a discretionary bonus for 2007, which shall be paid in the sole discretion of the Board but shall not be less than $50,000. The discretionary bonus for 2007 shall become due and payable only if the Executive
remains employed with the Company as of January 1, 2008. The Company shall pay the discretionary bonus for 2007 to the Executive on the same day that the Company pays bonuses to other executives of the Company, provided, however,
that the Company shall in no event pay the discretionary bonus for 2007 to the Executive after March 15, 2009. 
  

	 	(c)	Benefits; Relocation. During the Term, the Executive shall be eligible to participate in employee benefit plans, programs and arrangements of the Company, as may
be amended from time to time, which are generally applicable to senior officers of the Company and its subsidiaries, which as of the time of this Agreement include the Company’s health and welfare plan and the Equity Incentive Plan of Allison
Transmission Holdings, Inc. (pursuant to the terms to be set forth in a separate award agreement). During the Term, the Executive agrees to reside in the Indianapolis, Indiana area and agrees to relocate from New Jersey to the Indianapolis, Indiana
area within a reasonable period of time following the Effective Date. 

  

	 	(d)	Vacation. During the Term, the Executive shall be entitled to paid vacation in accordance with the Company’s vacation policy, as it may be amended from time
to time; provided, however, the Executive shall be entitled to no less than five (5) weeks of paid vacation each calendar year. Any vacation shall be taken at the reasonable and mutual convenience of the Company and the Executive.

  

	 	(e)	Expenses. During the Term, the Company shall reimburse the Executive for all reasonable travel and other business expenses incurred by him in the performance of
his duties to the Company in accordance with the Company’s expense reimbursement policy. 

  

	 	(f)	Key Person Insurance. At any time during the Term, the Company shall have the right to insure the life of the Executive for the Company’s sole benefit. The
Company shall have the right to determine the amount of insurance and the type of policy. The Executive shall reasonably cooperate with the Company in obtaining such insurance by submitting to physical examinations, by supplying all information
reasonably required by any insurance carrier, and by executing all necessary documents reasonably required by any insurance carrier. The Executive shall incur no financial obligation by executing any required document, and shall have no interest in
any such policy. 

  
 4 

	3.	Termination. 

 The
Executive’s employment hereunder may be terminated by the Company or the Executive, as applicable, without any breach of this Agreement only under the following circumstances: 

 

	 	(a)	Circumstances. 

  

	 	(i)	Death. The Executive’s employment hereunder shall terminate upon his death. 

 

	 	(ii)	Disability. If the Executive has incurred a Disability, as defined in Section 10(d), the Company may terminate the Executive’s employment.

  

	 	(iii)	Termination for Cause. The Company may terminate the Executive’s employment for Cause, as defined in Section 10(a). 

 

	 	(iv)	Termination without Cause. The Company may terminate the Executive’s employment without Cause. 

 

	 	(v)	Resignation for Good Reason. The Executive may resign his employment for Good Reason, as defined in Section 10(e). 	 

  

	 	(vi)	Resignation without Good Reason. The Executive may resign his employment without Good Reason. 

 

	 	(vii)	Non-extension of Term by the Company. The Company may give notice of non-extension to the Executive pursuant to Section 1(b). 

  

	 	(viii)	Non-extension of Term by the Executive. The Executive may give notice of non-extension to the Company pursuant to Section 1(b).

  

	 	(b)	 Notice of Termination. Any termination of the Executive’s employment by the Company or by the Executive under this Section 3
(other than termination pursuant to paragraph (a)(i)) shall be communicated by a written notice to the other Party hereto indicating the specific termination provision in this Agreement relied upon, setting forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated, and specifying a Date of Termination, as defined in Section 10(c), which shall be at least 60 days following
the date of such notice in the event of any termination of the Executive’s employment other than a Termination for Cause and at least 45 days following the date of such notice in the event of a Termination for Cause (a “Notice of
Termination”). The failure by the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the Company hereunder or preclude the Company from asserting
such fact or 

  
 5 

	 	 
circumstance in enforcing the Company’s rights hereunder. Similarly, the failure by Executive to set forth in the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason shall not waive any right of the Executive hereunder or preclude the Executive from asserting such fact or circumstance in enforcing Executive’s rights hereunder. 

 

	 	(c)	Company Obligations upon Termination. Upon termination of the Executive’s employment pursuant to any of the circumstances listed in
Section 3(a), the Executive (or the Executive’s estate) shall be entitled to receive the sum of: (i) the portion of the Executive’s Annual Base Salary earned through the Date of Termination, but not yet paid to the
Executive; (ii) any bonus actually earned by the Executive in the year prior to the year in which the Date of Termination occurs, but not yet paid to the Executive; (iii) any expenses owed to the Executive under Section 2(e);
(iv) any accrued vacation pay owed to the Executive pursuant to Section 2(d), and (v) any amount accrued and arising from the Executive’s participation in, or benefits accrued under any employee benefit plans, programs or
arrangements under Section 2(c), which amounts shall be payable in accordance with the terms and conditions of such employee benefit plans, programs or arrangements. (collectively, the “Company Arrangements”). For the
avoidance of doubt, upon termination of the Executive’s employment for any reason, the Executive shall not be entitled to any other payments or benefits (including Annual Base Salary) except as specifically provided for in this
Section 3(c) or Section 4. 

  

	4.	Severance Payments. 

  

	 	(a)	Termination for Cause, Resignation without Good Reason or upon Non-extension of Term by the Executive. If the Executive’s employment shall terminate
pursuant to Section 3(a)(iii) for Cause, Section 3(a)(vi) for the Executive’s resignation without Good Reason, or pursuant to Section 3(a)(viii) due to Non-extension of the Term by the Executive, the
Executive shall not be entitled to any severance payment or benefits. 

  

	 	(b)	Termination without Cause, Resignation for Good Reason, Death, Disability or upon Non-extension of Term by the Company. If the Executive’s employment shall
terminate without Cause pursuant to Section 3(a)(iv), shall terminate due to the Executive’s resignation for Good Reason pursuant to Section 3(a)(v), as a result of Executive’s death pursuant to
Section 3(a)(i) or Disability pursuant to Section 3(a)(ii), or pursuant to Section 3(a)(vii) due to Non-extension of the Term by the Company then, subject to the Executive signing, within fifty (50) days
following delivery to the Executive, and not revoking a release of claims against the Company in substantially the form attached hereto as Exhibit A (the “Release”) and the Executive’s continued compliance with
Sections 5 and 6, the Executive shall receive: 

  
 6 

	 	(i)	A lump sum payment equal to 1.25 times the Executive’s Annual Base Salary as of the Date of Termination, payable within sixty (60) days following the Date of
Termination, but subject to Executive’s execution of the Release, provided that he has not revoked such Release; 

  

	 	(ii)	A lump sum payment equal to 1.25 times the Executive’s Performance Bonus, which Performance Bonus will be based on the Performance Bonus that the Executive would
have earned had he remained employed through the end of the Company’s fiscal year in which the Date of Termination occurs (the “Termination Year”), but shall be calculated with reference to the performance of the Company
through the last day of the Company’s fiscal quarter that ended prior to the Date of Termination against performance goals for such Termination Year pro-rated to such date, as reasonably determined by the Board; provided, that, if the
Date of Termination occurs during the first quarter of a fiscal year, then the Company’s performance in such first quarter will be used to determine the amount of such Performance Bonus; provided further, that if the Date of Termination
occurs prior to the date that performance goals for the Termination Year are established by the Board, then the lump sum payment shall instead equal 1.25 times the Executive’s Target Bonus; provided further, that the payment provided for
under this subsection 4(b)(ii) is payable within sixty (60) days following the Date of Termination but subject to Executive’s execution of the Release, provided that he has not revoked such Release; and 

 

	 	(iii)	Reimbursement for, or direct payment to the carrier for, the premium costs under COBRA for the Executive and, where applicable, his spouse and dependents, for fifteen
months following the Date of Termination, under the same or a comparable Company group medical plan to the group medical plan that Executive was participating in as of the Date of Termination; provided that if the same or comparable Company group
medical plan is, at any time during such fifteen month period, not available generally to senior officers of the Company, the Executive shall receive reimbursement for, or direct payment to the carrier for, the premium costs under COBRA under a
group medical plan that is available to such senior officers of the Company. 

 If the payment of any amounts under
Section 4(b)(i) or (ii) are delayed pending the Executive’s execution of the Release, as soon as reasonably practicable following the date the Release becomes effective, the Company will pay the Executive the amounts that would
have otherwise been previously paid to the Executive under Section 4(b)(i) or (ii) prior to the execution of such Release, provided that he has not revoked such Release. For the avoidance of doubt, no payments or benefits under
Sections 4(b)(i), (ii) or (iii) shall be made until the 

  
 7 

 
Executive has executed the Release and the required revocation period specified in the Release has expired. 
  

	 	(c)	Survival. The expiration or termination of the Term shall not impair the rights or obligations of any Party hereto, which shall have accrued prior to such
expiration or termination. 

  

	5.	Competition. 

  

	 	(a)	The Executive shall not, at any time during the Term and for fifteen months after the Date of Termination, directly or indirectly engage in, have any equity interest
in, interview for a potential employment or consulting relationship with or manage or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant
or otherwise) that engages in any business which competes with any portion of the Business (as defined below) of the Company anywhere in the world. Notwithstanding the foregoing, it shall not be a violation of this Section 5(a) for the
Executive to join a division or business line of a commercial enterprise, other than any Specified Entity, with multiple divisions or business lines if such division or business line is not competitive with the businesses of the Company and its
subsidiaries, provided that the Executive performs services solely for such non-competitive division or business line, and performs no functions on behalf of (and has no involvement with or direct or indirect responsibilities with respect to)
businesses competitive with the Business of the Company anywhere in the world. Nothing herein shall prohibit the Executive from being a passive owner of not more than 4.9% of the outstanding equity interest in any entity, other than any Specified
Entity, which is publicly traded, so long as the Executive has no active participation in the business of such entity. 

  

	 	(b)	The Executive shall not, at any time during the Term and for fifteen months after the Date of Termination, directly or indirectly, recruit or otherwise solicit or
induce any employee, customer, subscriber or supplier of the Company (i) to terminate its employment or arrangement with the Company, or (ii) to otherwise change its relationship with the Company. 

 

	 	(c)	In the event the terms of this Section 5 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too
great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum
geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action. 

 

	 	(d)	 As used in this Section 5, (i) the term “Company” shall include the Company, its subsidiaries, and Allison
Transmission Holdings, Inc., the parent of the Company, 

  
 8 

	 	 
and (ii) the term “Business” shall include the manufacturing, development and sale of transmissions and the sale of replacement parts, “will-fit” parts, support
equipment and remanufactured transmissions for use in the vehicle aftermarket, as such business may be expanded or altered by the Company during the Term. 

 

	 	(e)	The Executive agrees, during the Term and following the Date of Termination, to refrain from disparaging the Company and its affiliates, including any of its services,
technologies or practices, or any of its directors, officers, agents, representatives or stockholders, either orally or in writing. The Company agrees, during the Term and following the Date of Termination, to refrain from disparaging the Executive;
provided, however, that the Company’s agreement to this non-disparagement clause shall be limited to official statements issued by the Company as an organization and statements of officers of the Company and members of the Board in their
official capacity as representatives of the Company. Nothing in this paragraph shall preclude the Executive, the Company, the members of the Board or officers of the Company from making truthful statements that are reasonably necessary to comply
with applicable law, regulation or legal process. 

  

	6.	Nondisclosure of Proprietary Information. 

  

	 	(a)	 Except in connection with the faithful performance of the Executive’s duties hereunder or pursuant to Section 6(c) and (e), the
Executive shall, in perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for his benefit or the benefit of any person, firm, corporation or other entity any confidential or
proprietary information or trade secrets of or relating to the Company (including, without limitation, business plans, business strategies and methods, acquisition targets, intellectual property in the form of patents, trademarks and copyrights and
applications therefor, ideas, inventions, works, discoveries, improvements, information, documents, formulae, practices, processes, methods, developments, source code, modifications, technology, techniques, data, programs, other know-how or
materials, owned, developed or possessed by the Company, whether in tangible or intangible form, information with respect to the Company’s operations, processes, products, inventions, business practices, finances, principals, vendors,
suppliers, customers, potential customers, marketing methods, costs, prices, contractual relationships, regulatory status, prospects and compensation paid to employees or other terms of employment) (collectively, the “Confidential
Information”), or deliver to any person, firm, corporation or other entity any document, record, notebook, computer program or similar repository of or containing any such Confidential Information. The Parties hereby stipulate and agree
that, as between them, any item of Confidential Information is important, material and confidential and affects the successful conduct of the businesses of the Company (and any successor or assignee of the Company). Notwithstanding the foregoing,
Confidential Information shall not include any information that has 

  
 9 

	 	 
been published in a form generally available to the public prior to the date the Executive proposes to disclose or use such information, provided, that such publishing of the Confidential
Information shall not have resulted from the Executive directly or indirectly breaching his obligations under this Section 6(a) or any other similar provision by which he is bound, or from any third-party breaching a provision similar to that
found under this Section 6(a). For the purposes of the previous sentence, Confidential Information will not be deemed to have been published or otherwise disclosed merely because individual portions of the information have been separately
published, but only if all material features comprising such information have been published in combination. 

  

	 	(b)	Upon termination of the Executive’s employment with the Company for any reason, the Executive will promptly deliver to the Company all correspondence, drawings,
manuals, letters, notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents or property concerning the Company’s customers, business plans, marketing strategies, products, property or processes.

  

	 	(c)	The Executive may respond to a lawful and valid subpoena or other legal process but shall give the Company the earliest possible notice thereof, shall, as much in
advance of the return date as possible, make available to the Company and its counsel the documents and other information sought and shall assist such counsel at Company’s expense in resisting or otherwise responding to such process.

  

	 	(d)	As used in this Section 6 and Section 7, the term “Company” shall include the Company, its subsidiaries, and Allison
Transmission Holdings, Inc., the parent of the Company. 

  

	 	(e)	Nothing in this Agreement shall prohibit the Executive from (i) disclosing information and documents when required by law, subpoena or court order (subject to the
requirements of Section 6(c) above), (ii) disclosing information and documents to his attorney or tax adviser for the purpose of securing legal or tax advice, (iii) disclosing the Executive’s post-employment restrictions
in this Agreement in confidence to any potential new employer, or (iv) retaining, at any time, his personal correspondence, his personal contacts and documents related to his own personal benefits, entitlements and obligations.

  

	7.	Inventions. 

 All
rights to discoveries, inventions, improvements and innovations (including all data and records pertaining thereto) related to the business of the Company, whether or not patentable, copyrightable, registrable as a trademark, or reduced to writing,
that the Executive may discover, invent or originate during the Term, either alone or with others and whether or not during working hours or by the use of the facilities of the Company (“Inventions”), shall be the exclusive property
of the Company. The Executive shall promptly disclose all Inventions to the Company, shall execute at the request of the Company any assignments or other documents the 

  
 10 

 
Company may deem reasonably necessary to protect or perfect its rights therein, and shall assist the Company, upon reasonable request and at the Company’s expense, in obtaining, defending
and enforcing the Company’s rights therein. The Executive hereby appoints the Company as his attorney-in-fact to execute on his behalf any assignments or other documents reasonably deemed necessary by the Company to protect or perfect its
rights to any Inventions. 
  

	8.	Injunctive Relief. 

It is recognized and acknowledged by the Executive that a breach of the covenants contained in Sections 5, 6 and 7 will cause
irreparable damage to Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a
breach of any of the covenants contained in Sections 5, 6 and 7, in addition to any other remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief. 

 

	9.	Assignment and Successors. 

 The Company may assign its rights and obligations under this Agreement to any successor to all or substantially all of the business or the assets of the Company (by merger or otherwise), and may assign or
encumber this Agreement and its rights hereunder as security for indebtedness of the Company and its affiliates. This Agreement shall be binding upon and inure to the benefit of the Company, the Executive and their respective successors, assigns,
personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable. None of the Executive’s rights or obligations may be assigned or transferred by the Executive, other than the
Executive’s rights to payments hereunder, which may be transferred only by will or operation of law. Notwithstanding the foregoing, the Executive shall be entitled, to the extent permitted under applicable law and applicable Company
Arrangements, to select and change a beneficiary or beneficiaries to receive compensation hereunder following his death by giving written notice thereof to the Company. 

 

	10.	Certain Definitions. 

  

	 	(a)	Cause. The Company shall have “Cause” to terminate the Executive’s employment hereunder upon: 

 

	 	(i)	the Board’s determination that the Executive failed to substantially perform his duties as an employee of the Company (other than any such failure resulting from
the Executive’s Disability) that is reasonably expected to result in, or has resulted in, material economic damage to the Company or any of its affiliates (provided, that, to the extent such failure can be fully cured, the Company shall have
provided the Executive with at least 30 days’ notice of such failure and the Executive has not remedied the failure within the 30-day period); 

  

	 	(ii)	 the Board’s determination that the Executive failed in any material respect

  
 11 

	 	 
to carry out or comply with any lawful and reasonable directive of the Board consistent with the terms of this Agreement (provided, that, to the extent such failure can be fully cured, the
Company shall have provided the Executive with at least 30 days’ notice of such failure and the Executive has not remedied the failure within the 30-day period); 

 

	 	(iii)	the Executive’s conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or crime involving moral
turpitude; 

  

	 	(iv)	the Executive’s unlawful use (including being under the influence) or possession of illegal drugs on the Company’s (or any of its affiliate’s) premises
or while performing the Executive’s duties and responsibilities under this Agreement; or 

  

	 	(v)	the Executive’s commission of an act of fraud, embezzlement, misappropriation, willful misconduct, or breach of fiduciary duty against the Company or any of its
affiliates. 

  

	 	(b)	Credit Agreement. “Credit Agreement” shall mean the Credit Agreement among Allison Transmission Holdings, Inc., the Company, Citicorp North America,
Inc., Lehman Brothers Commercial Bank and the other parties thereto, dated as of August 7, 2007 and any successor thereto. 

  

	 	(c)	Date of Termination. “Date of Termination” shall mean (i) if the Executive’s employment is terminated by his death, the date of his death;
(ii) if the Executive’s employment is terminated pursuant to Section 3(a)(ii) – (vi) either the date indicated in the Notice of Termination or the date specified by the Company pursuant to Section 3(b),
whichever is earlier; (iii) if the Executive’s employment is terminated pursuant to Section 3(a)(vii) or Section 3(a)(viii), the expiration of the then-applicable Term. 

 

	 	(d)	 Disability. “Disability” shall mean, at any time the Company or any of its affiliates sponsors a long-term disability plan for the
Company’s employees, “disability” as defined in such long-term disability plan for the purpose of determining a participant’s eligibility for benefits, provided, however, if the long-term disability plan contains multiple
definitions of disability, “Disability” shall refer to that definition of disability which, if the Executive qualified for such disability benefits, would provide coverage for the longest period of time. The determination of whether the
Executive has a Disability shall be made by the person or persons required to make disability determinations under the long-term disability plan. At any time the Company does not sponsor a long-term disability plan for its employees, Disability
shall mean the Executive’s inability to perform, with or without reasonable accommodation, the essential functions of his position hereunder for a total of three months during any six-month period as a result of incapacity due to mental or
physical illness as determined by a physician selected 

  
 12 

	 	 
by the Company or its insurers and acceptable to the Executive or the Executive’s legal representative, with such agreement as to acceptability not to be unreasonably withheld or delayed.
Any refusal by the Executive to submit to a medical examination for the purpose of determining Disability shall be deemed to constitute conclusive evidence of the Executive’s lack of a Disability. 

 

	 	(e)	Good Reason. The Executive shall have “Good Reason” to resign his employment within ninety (90) days following (i) a material diminution in
the Executive’s authorities, duties, or responsibilities, (ii) a material change in the geographic location at which the Executive must perform services, which shall not include a relocation of the Executive’s principal place of
employment to any location within a fifty (50) mile radius of the location from which the Executive served the Company immediately prior to the relocation, (iii) a material diminution in the Executive’s Annual Base Salary from the
Annual Base Salary in effect in the prior year, or (iv) a material diminution in the Executive’s Target Bonus from the Target Bonus in effect in the prior year. The Executive may not resign his employment for Good Reason unless the
Executive provided the Company with at least 30 days prior written notice of his intent to resign for Good Reason and the Company has not cured the breach within 30 days. 

(f) Specified Entity. “Specified Entity” shall mean any of the following, including their affiliates: (i) ZF
Friedrichshafen AG, (ii) Voith AG, (iii) Eaton Corporation, (iv) Caterpillar, Inc., and (v) ArvinMeritor, Inc. 
  

	11.	Governing Law. 

This Agreement shall be governed, construed, interpreted and enforced in accordance with its express terms, and otherwise in accordance
with the substantive laws of the State of Indiana, without reference to the principles of conflicts of law of the State of Indiana or any other jurisdiction, and where applicable, the laws of the United States. 

 

	12.	Validity. 

 The
invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 

 

	13.	Notices. 

 Any
notice, request, claim, demand, document and other communication hereunder to any Party shall be effective upon receipt (or refusal of receipt) and shall be in writing and delivered personally or sent by facsimile or certified or registered mail,

proceeding to vary the terms of this Agreement. 
  

	16.	Amendments; Waivers. 

 This Agreement may not be modified, amended, or terminated except by an instrument in writing, signed by the Executive and a duly authorized officer of Company. By an instrument in writing similarly
executed, the Executive or a duly authorized officer of the Company may waive compliance by the other Party or Parties with any specifically identified provision of this Agreement that such other Party was or is obligated to comply with or perform;

exercise of any other right, remedy, or power provided herein or by law or in equity. Except as otherwise set forth in this Agreement, the respective rights and obligations of the Parties under this Agreement shall survive any termination of the
Executive’s employment. 
  

	17.	No Inconsistent Actions. 

 The Parties hereto shall not voluntarily undertake or fail to undertake any action or course of action inconsistent with the provisions or essential intent of this Agreement. Furthermore, it is the intent

	18.	Construction. 

This Agreement shall be deemed drafted equally by both the Parties. Its language shall be construed as a whole and according to its fair
meaning. Any presumption or principle that the language is to be construed against any Party shall not apply. The headings in this Agreement are only for convenience and are not intended to affect construction or interpretation. Any references to
paragraphs, subparagraphs, sections or subsections are to those parts of this Agreement, unless the context clearly indicates to the contrary. Also, unless the context clearly indicates to the contrary, (a) the plural includes the singular and
the singular includes the plural; (b) “and” and “or” are each used both conjunctively and disjunctively; (c) “any,” “all,” “each,” or “every” means “any and all,” and
“each and every”; (d) “includes” and “including” are each “without limitation”; (e) “herein,” “hereof,” “hereunder” and other similar compounds of the word
“here” refer to the entire Agreement and not to any particular paragraph, subparagraph, section or subsection; and (f) all pronouns and any variations thereof shall be deemed to refer to the masculine, feminine, neuter, singular or
plural as the identity of the entities or persons referred to may require. 
  

	19.	Arbitration. 

 Any
controversy, claim or dispute arising out of or relating to this Agreement, shall be settled solely and exclusively by binding arbitration in Indianapolis, Indiana. Such arbitration 

  
 15

chosen by JAMS; (b) each Party to the arbitration will pay its pro rata share of the expenses and fees of the arbitrator, together with other expenses of the arbitration incurred or approved by the arbitrator; and (c) arbitration may
proceed in the absence of any Party if written notice (pursuant to the JAMS’ rules and regulations) of the proceedings has been given to such Party. Each Party shall bear its own attorneys fees and expenses. The Parties agree to abide by all
decisions and awards rendered in such proceedings. Such decisions and awards rendered by the arbitrator shall be final and conclusive. All such controversies, claims or disputes shall be settled in this manner in lieu of any action at law or equity;
provided, however, that nothing in this subsection shall be construed as precluding the bringing an action for injunctive relief as provided in Section 8. 
  

	20.	Enforcement. 

 If
any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if
such illegal, invalid or unenforceable provision had never comprised a portion of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision there shall be added automatically as part of this Agreement a provision as similar in terms to such illegal, invalid or
unenforceable provision as may be possible and be legal, valid and enforceable. 
  

	21.	Withholding. 

 The
Company shall be entitled to withhold from any amounts payable under this Agreement any federal, state, local or foreign withholding or other taxes or charges which the Company is required to withhold. The Company shall be entitled to rely on an
opinion of counsel if any questions as to the amount or requirement of withholding shall arise. 
  

	22.	Employee Acknowledgement. 

 The Executive acknowledges that he has read and understands this Agreement, is fully aware of its legal effect, has not acted in reliance upon any representations or promises made by the Company other
than those contained in writing herein, and has entered into this Agreement freely based on his own judgment. 
  

	23.	Section 409A. 

Notwithstanding anything to the contrary in this Agreement, if at the time of the Executive’s termination of employment with the
Company, the Executive is a “specified employee” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), as determined by the Company in accordance with Section 409A of the Code,
and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or 

  
 16 

 
additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in the payments
or benefits ultimately paid or provided to the Executive) until the date that is at least six (6) months following the Executive’s termination of employment with the Company (or the earliest date permitted under Section 409A of the
Code), whereupon the Company will pay the Executive a lump-sum amount equal to the cumulative amounts that would have otherwise been previously paid to the Executive under this Agreement during the period in which such payments or benefits were
deferred. Thereafter, payments will resume in accordance with this Agreement. 
 Additionally, in the event that following the
date hereof the Company or the Executive reasonably determines that any compensation or benefits payable under this Agreement may be subject to Section 409A of the Code, the Company and the Executive shall work together to adopt such amendments
to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (x) exempt the compensation and
benefits payable under this Agreement from Section 409A of the Code and/or preserve the intended tax treatment of the compensation and benefits provided with respect to this Agreement or (y) comply with the requirements of
Section 409A of the Code and related Department of Treasury guidance. 
  

	23.	Indemnification. 

The Company shall indemnify the Executive to the maximum extent permitted under the General Corporation Law of the State of Delaware for
acts taken within the scope of his employment. To the extent that the Company obtains coverage under a director and officer indemnification policy, the Executive will be entitled to such coverage on a basis that is no less favorable than the
coverage provided to any other officer or director of the Company.

 Exhibit A 

General Release and Waiver* 

For and in consideration of the payments and other benefits due to David S. Graziosi (the “Executive”) pursuant to the
Employment Agreement, dated as of November 1, 2007, by and between Allison Transmission, Inc. (the “Company”) and the Executive (the “Employment Agreement”), and for other good and valuable consideration, the
Executive hereby agrees, for the Executive, the Executive’s spouse and child or children (if any), the Executive’s heirs, beneficiaries, devisees, executors, administrators, attorneys, insurers, personal representatives, successors and
assigns, to forever release, discharge and covenant not to sue (the “Release”) the Company, or any of its divisions, affiliates, subsidiaries, parents, branches, predecessors, successors, assigns, and, with respect to such entities,
their officers, directors, trustees, employees, agents, shareholders, administrators, general or limited partners, representatives, attorneys and fiduciaries, past, present and future (the “Released Parties”) from any and all claims
of any kind arising out of, or related to, his employment with the Company, its affiliates and subsidiaries (collectively, with the Company, the “Affiliated Entities”), the Executive’s separation from employment with the
Affiliated Entities, which the Executive now has or may have against the Released Parties, whether known or unknown to the Executive, by reason of facts which have occurred on or prior to the date that the Executive has signed this Release. Such
released claims include, without limitation, any and all claims relating to the foregoing under federal, state or local laws pertaining to employment, including, without limitation, the Age Discrimination in Employment Act, Title VII of the Civil
Rights Act of 1964, as amended, 42 U.S.C. Section 2000e et. seq., the Fair Labor Standards Act, as amended, 29 U.S.C. Section 201 et. seq., the Americans with Disabilities Act, as amended, 42 U.S.C.
Section 12101 et. seq. the Reconstruction Era Civil Rights Act, as amended, 42 U.S.C. Section 1981 et. seq., the Rehabilitation Act of 1973, as amended, 29 U.S.C. Section 701 et. seq., the
Family and Medical Leave Act of 1992, 29 U.S.C. Section 2601 et. seq., and any and all state or local laws regarding employment discrimination and/or federal, state or local laws of any type or description regarding employment,
including but not limited to any claims arising from or derivative of the Executive’s employment with the Affiliated Entities, as well as any and all such claims under state contract or tort law. 

The Executive has read this Release carefully, acknowledges that the Executive has been given at least twenty-one (21) days to
consider all of its terms and has been advised to consult with an attorney and any other advisors of the Executive’s choice prior to executing this Release, and the Executive fully understands that by signing below the Executive is voluntarily
giving up any right which the Executive may have to sue or bring any other claims against the Released Parties, including any rights and claims under the Age Discrimination in Employment Act. The Executive also understands that the Executive has a
period of seven (7) days after signing this Release within which to revoke his agreement, and that neither the Company nor any other 
  
  

	* 	 The Company may adjust the terms of this form release from time to time, including, without limitation, to reflect any changes in applicable laws.

  
 19 

 
person is obligated to make any payments or provide any other benefits to the Executive pursuant to the Employment Agreement until eight (8) days have passed since the Executive’s
signing of this Release without the Executive’s signature having been revoked other than any accrued obligations or other benefits payable pursuant to the terms of the Company’s normal payroll practices or employee benefit plans. Finally,
the Executive has not been forced or pressured in any manner whatsoever to sign this Release, and the Executive agrees to all of its terms voluntarily. 
 Notwithstanding anything else herein to the contrary, this Release shall not affect: (i) the Company’s obligations under any compensation or employee benefit plan, program or arrangement
(including, without limitation, obligations to the Executive under any stock option, stock award or agreements or obligations under any pension, deferred compensation or retention plan) provided by the Affiliated Entities where the Executive’s
compensation or benefits are intended to continue or the Executive is to be provided with compensation or benefits, in accordance with the express written terms of such plan, program or arrangement, beyond the date of the Executive’s
termination; or (ii) rights to indemnification or liability insurance coverage the Executive may have under the by-laws of the Company or applicable law. 
 This Release is subject to Sections 11 and 19 of the Employment Agreement. This Release is final and binding and may not be changed or modified except in a writing signed by both parties.
