Remanufactured NV4500 Manual Transmission

The Zumbrota Drivetrain RMT4500C-17 is a remanufactured NV4500 manual transmission engineered for 1992-1994 GM P-series 2WD applications. This unit ensures reliability through a rigorous remanufacturing process, involving three distinct quality inspections. A pre-inspection identifies potential issues like case cracks or excessive wear, while a second inspection verifies all components meet OEM specifications. The final post-build inspection confirms the transmission adheres to strict standards. This transmission features a durable cast iron case and a detachable bell housing for versatility. It is equipped with an external slave cylinder and a round push-and-twist style shift lever retainer. The emergency brake is conveniently mounted on the tail housing. Key technical specifications include a bolt-on yoke retention system (not a nut) and a 1.771-inch diameter seal surface on the output yoke. The main case is cast with the number 16812. All internal parts undergo a comprehensive inspection, including gear wear checks, mainshaft straightness tests, and synchronizer testing. To ensure peak performance and functionality, all transmissions are dynometer tested and subjected to numerous real-life scenarios before shipment. This meticulous testing guarantees the unit is ready to perform under various operating conditions.
