M5R1 Remanufactured 5-Speed Manual Transmission

The Zumbrota Drivetrain M5R1 manual transmission is a remanufactured unit engineered for 1990-1994 Ford Ranger, 1991-1994 Ford Explorer, 1991-1994 Mazda Navajo, and 1994 Mazda B4000 vehicles equipped with the 4.0L 6-cylinder engine and 4WD. This all-aluminum transmission features a 5-speed configuration and a shifter that bolts directly into the top cover. It includes specific details such as a 4.625-inch shifter stub length, a two-switch top cover, and a tail housing with a transfer case shifter mounting boss. Notably, this unit does not come with a speedometer gear or vehicle speed sensor, and it lacks a bottom pan. Zumbrota Drivetrain emphasizes a rigorous remanufacturing process, involving quality inspections at three stages: pre-inspection for core issues, during the remanufacturing process to meet OEM specifications, and a final post-build inspection. All internal parts are inspected 100%, with common wear components like seals and bearings replaced. The transmissions are dyno-tested to ensure performance in various scenarios. Units are shipped in high-density plastic totes to prevent damage. Important shipping considerations apply: this item must ship to an address with a loading dock or forklift and is not intended for residential delivery. Shipping to Alaska or Hawaii requires a custom quote, and expedited shipping is unavailable. Customers are also advised that their Vehicle VIN will help guarantee fitment. A $400 refundable core charge applies.
