ITEM 5.  OTHER EVENTS.

         On September 1, 2000, Aftermarket Technology Corp. (the "Company")
entered into an agreement with an affiliate of The Riverside Company ("Buyer")
to sell to Buyer all of the capital stock of the Company's ATC Distribution
Group, Inc. subsidiary (the "Distribution Group") for a purchase price of $77
million, which will be comprised of $65 million in cash and $12 million of
Buyer's Series B preferred stock (which has a present value of approximately $8
million). The cash proceeds from the sale will be used by the Company to retire
senior debt. The cash portion of the purchase price is subject to increase or
decease if the Distribution Group's net working capital as of closing is above
or below a specified target amount.

         The completion of the sale of the Distribution Group, which is subject
to regulatory approval, Buyer obtaining necessary financing and the satisfactory
completion of Buyer's environmental diligence, is expected to occur in October
2000. No assurance can be given that the sale will be successfully completed.

         The Distribution Group is part of the Company's Independent Aftermarket
business segment, which the Company recently decided to discontinue. The
Distribution Group distributes remanufactured transmissions and related drive
train components to independent aftermarket customers for use in the repair of
automobiles and light trucks primarily following expiration of the new vehicle
warranty. The sale of the Distribution Group does not affect the Company's OEM
business segment, which remanufactures transmissions for original equipment
manufacturers.

         The Riverside Company is an investment firm that, through one of its
funds, also owns another transmission repair parts business, Aceomatic-Recon
LLC.
