M5R1 Manual Transmission

The Zumbrota Drivetrain M5R1 is a remanufactured manual transmission engineered for specific Ford vehicles. This transmission is designed for 1988-1992 Ford Ranger models equipped with the 2.9L engine and 2WD drivetrain, featuring a 6-tooth purple speedo gear. Constructed with an all-aluminum housing, this M5R1 transmission is built to stringent quality standards, undergoing three separate quality inspections during the remanufacturing process. A pre-inspection ensures the unit is free from case cracks and excessive wear. During remanufacturing, all component parts are verified to meet OEM specifications, and a final post-build inspection confirms adherence to Zumbrota's strict standards. Internal components undergo 100% inspection, including gear wear checks, mainshaft straightness tests, and synchronizer testing. Furthermore, all transmissions are dyno-tested to simulate real-life scenarios before shipment. Key technical specifications include an all-aluminum construction, a shift lever that bolts into the top cover (no bottom pan), a 4-5/8 inch long shifter stub, and a two-switch top cover. The transmission also features a 6-tooth purple speedo gear. Compatible tag numbers include E87A-NC, E87A-ND, E87A-NE, E87A-NF, E87A-NG, E97A-EA, F57A-CA, and F57A-EA, with Hollander numbers 400-02433C and 400-03300. This transmission is specifically for the 1988-1992 Ford Ranger 2.9L, 2WD configuration. While the product listing indicates it is for the Ford Ranger, it is also compatible with the Ford Bronco II RWD from 1988-1990.
