The Duramax Tuner Custom Tuned Transmission Control Module (TCM) for your 2001-2010 GM 6.6L Duramax maximizes the tuning capabilities and performance of your Allison transmission. When larger turbo chargers are added, the usable RPM range is shifted up. Engine speeds where a stock turbocharger would be happy, may be laggy, smokey, or hot on the pyro after the addition of a larger turbo. Tuning the Allison transmission in your truck is the best tool available for making sure the engine is operating within its preferred rev range. Trans tuning yields less smoke, lower EGTs, better throttle response, less turbo lag, and quicker track times.
The Transmission controller is located on the drivers side of the radiator shroud of all Duramax powered GM's. Please fill in the mandatory VIN field and Turbo type fields. To maximize tuning capabilities and transmission performance, your ECM must also be tuned by Duramax Tuner.
- Less Smoke
- Lower EGT's
- Less Turbo Lag
- Better Throttle Response
- Quicker Track Times
Note: This is a custom tuned TCM that will be physically sent to you. You must take your stock unit and replace it with the tuned TCM. If you are purchasing a Duramax Tuner Spade Tuner at the same time, you can opt for the Email TCM tunes that will tune the existing TCM already in your truck. (see below)
