Description
The Zumbrota Remanufactured Manual Transmission, part number RMT4500D-6, is a remanufactured five-speed unit with a cast-iron case and a 1.250-inch input shaft. It is sold individually. Have your vehicle identification number (VIN) ready when ordering.
Zumbrota’s remanufacturing process includes inspections before, during, and after the build. The initial inspection checks for case cracks, excessive wear, and other issues associated with the original-equipment design. During remanufacturing, component parts are checked against OEM specifications; a final inspection checks the completed unit against Zumbrota’s standards.
- Internal parts receive a 100% inspection, including gear-wear checks, main-shaft straightness testing, and synchronizer testing.
- Seals, bearings, and other common wear components are replaced.
- Housings and top covers are cleaned using a hydro-blasting and rinsing process intended to restore an OEM-style finish.
- Units are shipped in high-density plastic totes to help reduce in-transit damage.
Configuration: Bellhousing, yoke, and shifter are not included. Confirm application details using your VIN before ordering.
