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 original-equipment cores. During remanufacturing, component parts are checked against OEM specifications, followed by a final inspection to confirm the unit meets Zumbrota’s build standards.
- Internal parts receive a 100% inspection, including gear-wear checks, a main-shaft straightness test, and synchronizer testing.
- Seals, bearings, and other common wear components are replaced.
- Housing and top covers are hydro-blasted and rinsed to restore an OEM-style finish.
- The transmission is shipped in a high-density plastic tote intended to help prevent damage in transit.
Zumbrota’s product line includes remanufactured 5-speed, 6-speed, and transaxle units; the supplied listing does not specify this part’s gear count or vehicle fitment. Confirm application compatibility before ordering. The source warranty statement applies to transfer cases, so it does not establish warranty coverage for this transmission.
