Remanufacturing Process

Every remanufactured transmission we sell is backed by a Million Mile warranty up to 7 years, the best in the industry. The reason we can offer this warranty? Every transmission undergoes the same rigorous remanufacturing process:

1. Teardown and Triple Clean – Every transmission is disassembled, inspected, and cleaned three times. We also chase all threads and install all new bushings during this process.
2. New or Re-machined Parts – Gear wear is checked and worn gears are replaced. Mainshaft straightness is tested and replaced if needed. Clutch disc synchronizers, selector fork, and flywheel are re-machined or replaced as needed.
3. Dyno Testing – Our custom dyno testing machines spin and load test every transmission to verify it’s ready for the road.

When you buy a remanufactured transmission from Powertrain Products, you’re buying a transmission that meets or exceeds OEM specifications. And we back that claim up with our available 7 Year, 1 Million Mile Warranty.
