R151T-1 Remanufactured Manual Transmission

The Zumbrota RMTR151T-1 is a remanufactured R151 manual transmission, specifically engineered for 1990-1995 Toyota Pickup, 4Runner, and 1993-1994 T100 vehicles equipped with the 3.0L engine and 4WD drivetrain. This 5-speed transmission features an 8-bolt front retainer and requires 3.2 quarts of 75W-90 GL-4 transmission fluid, which is not included. Zumbrota Drivetrain prioritizes quality through a meticulous three-step remanufacturing and inspection process. Initially, a pre-inspection identifies case cracks, excessive wear, and common OEM core issues. During the rebuild, component parts are measured to ensure they meet OEM specifications. Finally, a post-build inspection verifies that each unit adheres to strict quality standards. Critical components like shaft straightness, gear wear, and synchronizers undergo extensive testing. To guarantee optimal performance and reliability, all transmissions are dyno-tested to assess operation, shiftability, and noise levels. Furthermore, Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This comprehensive approach ensures a high standard of manual transmission remanufacturing, focusing on unit precision and reliability at all critical touchpoints.
