Remanufactured NV4500 Manual Transmission

The Zumbrota Drivetrain RMT4500C-6 is a remanufactured NV4500 manual transmission meticulously rebuilt to meet stringent quality standards. This transmission is engineered for 1996-1998 GM 2500 and 3500 pickup trucks with 2WD drivetrains. It features a durable cast iron case, a detachable bell housing for easier installation, and an internal slave cylinder. The shift tower is a distinctive square four-bolt configuration, and it incorporates a bolt-in speed sensor for compatibility. During the remanufacturing process, Zumbrota Drivetrain conducts three thorough quality inspections. An initial pre-inspection ensures the core unit is free from case cracks and excessive wear. A second inspection verifies that all component parts meet OEM specifications, and a final post-build inspection confirms adherence to Zumbrota's strict standards. This includes a 100% inspection of internal parts, such as gear wear checks and mainshaft straightness testing, along with synchronizer functionality testing. All transmissions are dyno-tested to simulate real-life scenarios before shipment. This specific model, RMT4500C-6, is designed for 2WD applications and explicitly excludes the C3500HD model. It features a square shifter stub opening in the top cover and does not include a brake. The rear output yoke is secured with a nut, not a bolt. Key casting numbers for the main case include 18157 or 23167, for the top cover 18860 or 25137, and for the tail housing 16808. Hollander numbers associated with this unit are 400-02936, 400-02937, 400-03098, and 400-03099.
