Quality
Remanufactured vs. Rebuilt
Rebuilds only repair to the level of failure, meaning any remaining components are unchanged. FleetPride transmissions and differentials are totally remanufactured, returning them to the latest blueprint specifications and tested to OEM standards.
Testing
All units are dynamometer tested to ensure they meet the strictest standards. Testing is based on OEM specifications for each unit. Contact your local branch for additional information. Find us at www.fleetpride.com/find-branch.

Manual Transmissions
- All builds conducted by an Eaton Authorized rebuilder.
- Every core is 100% disassembled, eliminating keyway failures and gear spin. It also ensures perfect timing of gears for assembly. The teardown of shift covers eliminates shift failures and allows for full inspection of shift rails, detents and inter-locks. Springs and poppets are replaced.
- Key parts are replaced with new, not re-used:
- New, OEM-approvedbearings. Transmission longevity starts with bearing life
- New entire air system, ensuring transmission shifts at the OEM air pressure — no slow or sluggish shifting or range shifts
- New input shafts, ensuring 100% spline life and 100% fit to flywheel pilot bearing
- New sliding clutches and synchronizers, critical to main shaft gear life and avoiding premature fork wear
- All units are dyno tested while under load. This simulates actual service use and brings it up to operating temperature where shift quality can be verified
