What is the Certified Difference?
We Remanufacture, not Rebuild
Rebuilding means only fixing the broken parts. Remanufacturing means:
- Completely disassembling and inspecting the unit
- Replacing all soft parts (clutches, seals, etc.) with new ones
- Checking all hard parts, and re-machine the worn ones
- Bring unit back to like-new quality, including any OEM updates
- Stress-testing the finished unit
Nationwide 3 Year/50,000 Mile Warranty
Our nationwide coverage is among the best in the industry.
We proudly stand behind our work with a standard 3 year/50,000 mile warranty.
If your transmission is installed by one of our Certified retail stores, we also offer an extended 5 year/75,000 mile warranty.
Certified gives you peace of mind.
