Several years in the making.
After purchasing Factory Tech Transmissions in April of 2012, we spent the last couple years setting up the lathes and mills to cut special parts, installing blast cabinets, paint booths, and our state of the art $250,000 dynamometer powered by BlueReach Automation. We can duplicate actual driving and load conditions in a truck, including all upshifts and downshifts.

Many more modifications we do to improve performance and reliability
The transmission is shipped to you in a molded shipping container. We must get this case back with your transmission core. If you send back your core without the case, you will only get 1000.00 of your core fee returned. The case has a 200.00 core fee on it. If you ordered a TC and do not send your tc core back with your transmission, there will be another 50.00 deducted.
