| Basis of Presentation and Consolidation                    | Basis of Presentation and ConsolidationThe accompanying unaudited consolidated financial statements include the assets, liabilities, and results of operations of our Manufacturing operations, which include majority-owned dealers ("Dealcors"), and our Financial Services operations, including VIEs of which we are the primary beneficiary. The effects of transactions among consolidated entities have been eliminated to arrive at the consolidated amounts. Certain reclassifications were made to prior periods' amounts to conform to the 2014 presentation, which relates to the realignment of our reporting segments that became effective during the fourth quarter of 2013.We prepared the accompanying unaudited consolidated financial statements in accordance with United States ("U.S.") generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by U.S. GAAP for comprehensive annual financial statements.The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting policies described in our Annual Report on Form 10-K for the year ended October 31, 2013, which should be read in conjunction with the disclosures therein. In our opinion, these interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial condition, results of operations, and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of annual operating results.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
| Variable Interest Entities                                 | Variable Interest EntitiesWe have an interest in several VIEs, primarily joint ventures, established to manufacture or distribute products and enhance our operational capabilities. We have determined for certain of our VIEs that we are the primary beneficiary because we have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and have the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Accordingly, we include in our consolidated financial statements the assets and liabilities and results of operations of those entities, even though we may not own a majority voting interest. The liabilities recognized as a result of consolidating these VIEs do not represent additional claims on our general assets; rather they represent claims against the specific assets of these VIEs. Assets of these entities are not readily available to satisfy claims against our general assets.We are the primary beneficiary of our Blue Diamond Parts ("BDP") and Blue Diamond Truck ("BDT") joint ventures with Ford Motor Company ("Ford"). As a result, our Consolidated Balance Sheets include assets of $201 million and $323 million and liabilities of $186 million and $188 million as of January 31, 2014 and October 31, 2013, respectively, from BDP and BDT, including $65 million and $56 million of cash and cash equivalents, at the respective dates, which are not readily available to satisfy claims against our general assets. The creditors of BDP and BDT do not have recourse to our general credit. In December 2011, Ford notified the Company of its intention to dissolve the BDT joint venture effective December 2014. In September 2013, we agreed with Ford to extend the BDT joint venture through February 2015. We do not expect the dissolution of the BDT joint venture to have a material impact on our consolidated financial statements.Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include assets of $946 million and $989 million as of January 31, 2014 and October 31, 2013, respectively, and liabilities of $752 million and $778 million as of January 31, 2014 and October 31, 2013, respectively, all of which are involved in securitizations that are treated as asset-backed debt. In addition, our Consolidated Balance Sheets include assets of $73 million and $61 million and corresponding liabilities of $58 million and $49 million as of January 31, 2014 and October 31, 2013, respectively, which are related to other secured transactions that do not qualify for sale accounting treatment, and therefore, are treated as borrowings secured by operating and finance leases. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that the related trusts are required to make principal and interest payments. Investors in securitizations of these entities have no recourse to our general credit.We also have an interest in other VIEs, which we do not consolidate because we are not the primary beneficiary. Our financial support and maximum loss exposure relating to these non-consolidated VIEs are not material to our financial condition, results of operations, or cash flows.We use the equity method to account for our investments in entities that we do not control under the voting interest or variable interest models, but where we have the ability to exercise significant influence over operating and financial policies. Equity in loss (income) of non-consolidated affiliates includes our share of the net income (loss) of these entities. |

Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. Inthe first quarter of 2014, we recorded adjustments for changes in estimates of $52 million or $0.64 per diluted share. Inthe first quarter of 2013, we recorded adjustments for changes in estimates of $40 million or $0.50 per diluted share. The impact of income taxes on the 2014 and 2013 adjustments is not material due to our deferred tax valuation allowances on our U.S. deferred tax assets(B)In the first quarter of 2013, we recognized $13 million of charges for adjustments to pre-existing warranties for a specific warranty issue related to component parts from a supplier. Also during the first quarter of 2013, we reached agreement for reimbursement from this supplier for this amount and other costs previously accrued. As a result of this agreement, we recognized a recovery of $27 million within Costs of products sold and recorded a receivable within Other current assets.Extended Warranty ProgramsThe amount of deferred revenue related to extended warranty programs was $427 million and $420 million at January 31, 2014 and October 31, 2013 respectively. Revenue recognized under our extended warranty programs was $27 million and $29 million in the three months ended January 31, 2014 and 2013, respectively.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |
| Use of estimates                                           | Use of EstimatesThe preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods presented. Significant estimates and assumptions are used for, but are not limited to, pension and other postretirement benefits, allowance for doubtful accounts, income tax contingency accruals and valuation allowances, product warranty accruals, asbestos and other product liability accruals, asset impairment charges, and litigation-related accruals. Actual results could differ from our estimates.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
| Concentration Risks                                        | Concentration RisksOur financial condition, results of operations, and cash flows are subject to concentration risks related to concentrations of our union employees. As of January 31, 2014, approximately 5,700, or 64%, of our hourly workers and approximately 400, or 6%, of our salaried workers are represented by labor unions and are covered by collective bargaining agreements. Our current master collective bargaining agreement with the UAW will expire in October 2014. Our future operations may be affected by changes in governmental procurement policies, budget considerations, changing national defense requirements, and global, political, regulatory and economic developments in the U.S. and certain foreign countries (primarily Canada, Mexico, and Brazil).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |
| Goodwill and Intangible Assets, Policy [Policy Text Block] | GoodwillGoodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit. We have a goodwill balance of $170 million as of January 31, 2014.  During the first quarter of 2014, a Brazilian reporting unit with goodwill of $132 million experienced declines in actual and forecasted results and cash flow. As a result of these factors as well as slower than expected growth in the Brazilian economy and a weakening of the Brazilian currency, we performed an impairment analysis in the first quarter. The income approach which is based on discounted cash flows which are derived from internal forecasts and economic expectations was used in the impairment analysis of the reporting unit. As a result of the goodwill impairment analysis, we determined that the goodwill was not impaired and that the fair value of the reporting unit exceeded its carrying amount by less than 10%.It is reasonably possible that within the next twelve months, we could recognize goodwill or other impairment charges, which could be material, if among other things, we experience adverse changes in our business including declines in profitability due to changes in volume, market pricing, cost, or the business environment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |

| - Definition
Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.
