Kennedy TCM for 01-05 Allison 1000 transmissions
This is a special TCM file that has been proven to improve track times. We will be programming customer units for exchange, or we can often supply a good used core. It is in no way a custom tune. It is simply Allison programming that we have customized and found to work very well. Shift speed programming runs much like the Tow Haul mode on the factory TCM. Shifts are generally much firmer as the TCC remains locked during upshift and downshift operations. Easily swapped in a matter of minutes. Overdrive lockout will not function and 2001/2 trucks will likely not show the gear position highlight when shifted to OD on the selector. It will be in gear, the highlight will just go blank.
