Remanufactured NV4500 Manual Transmission

The Zumbrota Drivetrain RMT4500C-19 is a remanufactured NV4500 manual transmission meticulously built for 1994-1995 GM P-Truck vehicles, specifically for 2WD configurations. This transmission is characterized by its external slave cylinder, a square four-bolt shift tower opening in the top cover, and an integrated provision for an emergency brake mounted on the tail housing. It utilizes a bolt to secure the rear output yoke, rather than a nut, and features a 1.771-inch diameter seal surface on the yoke. Zumbrota Drivetrain emphasizes a rigorous remanufacturing process for this transmission. Quality inspections are performed at three distinct stages: a pre-inspection to identify and reject cores with case cracks, excessive wear, or other OEM-related issues; a mid-process inspection to ensure all component parts adhere to OEM specifications; and a final post-build inspection to verify adherence to Zumbrota's strict standards. Furthermore, 100% inspection of all internal components, including gear wear checks, mainshaft straightness tests, and synchronizer testing, is conducted. To guarantee performance, all transmissions are dynometer tested and run through numerous real-life scenarios before shipping. This remanufactured transmission is built to order and includes a refundable core charge of +$1,500, which is returned upon receipt of the old, salvageable part. Zumbrota Drivetrain offers additional support, including live tech support and readily available sales representatives, to assist with fitment questions or build project selection.
