NV4500 Manual Transmission

The Zumbrota Drivetrain RMT4500C-13 is a meticulously remanufactured NV4500 manual transmission, engineered for durability and performance. This transmission features a robust cast iron case and a detachable bell housing. It incorporates an internal slave cylinder and a square four-bolt shift tower. Notably, reverse is not synchronized, and it is equipped to accommodate an emergency brake mounted on the tail housing (emergency brake unit not included). The rear output yoke is secured by a nut, not a bolt. This unit is specifically designed for 1996-1998 GM C3500HD 2WD models. Zumbrota Drivetrain employs a rigorous remanufacturing process involving three distinct quality inspection stages. A thorough pre-inspection identifies and rejects cores with case cracks or excessive wear. During the remanufacturing process, all component parts are inspected to ensure they meet or exceed OEM specifications. Finally, a comprehensive post-build inspection guarantees the transmission is assembled to the company's exacting standards. Every internal part, including gears, synchronizers, and the mainshaft, is subjected to 100% inspection.
