S5-42 5-Speed Manual Transmission

The Zumbrota Drivetrain S5-42 manual transmission is a remanufactured unit built to precise specifications for 1987-1995 Ford F-250 and F-350 4WD trucks. It is engineered for vehicles powered by the 6.9L or 7.3L diesel engines and is specifically designed for applications where the Power Take-Off (PTO) is not in use. This S5-42 transmission features a robust 5.72:1 first gear ratio, contributing to efficient operation. Zumbrota Drivetrain emphasizes quality control throughout their remanufacturing process. Each transmission is subjected to three thorough quality inspections: a pre-inspection to detect case cracks and excessive wear, an in-process inspection to verify component parts meet OEM standards, and a final post-build inspection to ensure adherence to strict quality requirements. Internal components, including gear wear, mainshaft straightness, and synchronizer function, are meticulously checked. Furthermore, every completed transmission is dynometer tested to simulate various real-life operating conditions. This remanufactured transmission is built to order and includes a refundable core charge, which is returned upon receipt of your old, salvageable part.
