2011 EXT TCM-Shiftfirmness not working?
I tried it in my g8 as my truck was in the shop... It only shifted firmer because of your PCM tuning, but doesn't seem to shift any firmer on most of the shifts except full throttle. I have to assume I am asking to much from the programmer as I miss my hd2 in a 4l60e and the 6l80e's aren't the same. I have a guy who is willing to offer me a buck 25 for the trinity. I am thinking about taking it as it just doesn't work on my vehicles for tranny tune and I must be the only one. I appreciate the time spent on your end.
Even worse, I thought I would try one more time and it put the pcm tune but no tcm tune.... I went back to stock to update the tool and it said backup was written but it was really quick... Then I updated the tool with my custom tunes from lew and went back and now it says backup failed as it looks like a diablo tune, but the tool isn't married when I check last tune written... Do I have to pay the dealer or do you have another way to fix this? Now I am totally stuck...
