6-Speed Manual Transmission

The Zumbrota Drivetrain S6-S650F is a remanufactured 6-speed manual transmission designed for 2008-2010 Ford F-Series trucks equipped with either the 5.4L or 6.8L engine. This transmission features a robust ZF-built design with integral front and rear cases, a 4-bolt shifter stub, and a specific gear ratio of 5:79 for low range and 0:72 for overdrive. Its construction is aimed at providing reliable performance for heavy-duty applications. Zumbrota Drivetrain emphasizes quality throughout their remanufacturing process. Each unit undergoes three distinct quality inspections: a pre-inspection to check for case cracks and excessive wear, a second inspection during remanufacturing to ensure all components meet OEM specifications, and a final post-build inspection to guarantee adherence to their strict standards. Internal parts are 100% inspected, including checks for gear wear, mainshaft straightness, and synchronizer function. Furthermore, every remanufactured S6-S650F transmission is dyno tested to simulate real-life scenarios, ensuring optimal performance and durability before it leaves their facility. The transmission is built to order and ships when ready, with options for expedited shipping available at checkout. A refundable core charge applies, which is returned upon receipt of the old, salvageable part.
