~~Power Performance is proud to offer transmission tuning for your Allison 5 and 6 speed equipped duramaxes! Our transmission tuning will allow for the torque converter to be applied in second gear (while in tow haul-request otherwise if you want it for more than just tow haul). This is good for knocking off close to at least .05 off your track times! No more lock up boxes needed, we handle it all by a simple flash!
Transmission tuning is super beneficial to trucks running bigger than stock turbo applications, it is really nice to stay on top of the charger at part throttle and not “bog down” in between shifts along with if you have big tires for more inviting downshifts!
Please list your vin number and your mods into the checkboxes below and also if you have special instructions:
