Description

The Zumbrota Drivetrain S6-S650F Manual Transmission Assembly is a remanufactured unit built for Ford F-Series trucks equipped with the 7.3L V8 engine and RWD. This 6-speed transmission boasts a high torque capacity and a gear ratio of 5.79 Low - 0.72, offering robust performance for heavy-duty applications. Zumbrota Drivetrain emphasizes quality through a rigorous remanufacturing process. This includes a pre-inspection to identify core issues, a second inspection during remanufacturing to ensure component specifications are met, and a final post-build inspection. All internal parts undergo 100 percent inspection, including gear wear and straightness tests. Seals, bearings, and common wear components are replaced, and housings are cleaned to an OEM finish via hydro blasting. All transmissions are dynometer tested through numerous real-life scenarios before shipping in protective totes to minimize transit damage. This unit is backed by a Standard 2 Year/Unlimited Mileage Warranty for vehicles up to 3/4 tons. This transmission is specifically designed for the 2001-2003 Ford F-250, F-350, and F-450 Super Duty models, as well as the 2002-2003 Ford F-550 Super Duty models, all with the 7.3L engine and RWD configuration. Note that this product requires freight shipping to an address with a loading dock or forklift; residential delivery is not available. Shipping to Alaska or Hawaii requires a custom quote, and expedited shipping is not offered for freight items. Customers are advised to verify fitment manually or by calling customer service with their VIN.
