Ever since I opened my exhaust up I can hear every shift loudly through my exhaust. must be due to no TM on the ECM. You can't turn off TM on the Trans on the 6L80's according to Blackbear. I don't know if I like having it off though. I don't think my tranny will last long the way I drive it lol. If only I could figure out how to tune myself...

My advice...go to a local tuner who can also tune the TCM. If will feel like a whole new truck.

Well I had a road tune from BB and he tried a few different things n made it better but doesn't feel like a good 'ol 4 speed bangin gears. Hes able to tune it with EFI live but he said the new Trans use clutches to shift more vs servos like the older ones so there's something's you just can't adjust. Don't know if that's smoke up my *** or not but I don't think he would want unhappy customers making me believe it's true.
