I seem to have no to way to look at the trasmission control module at all with my efi live and I am having serioius shifting issues with the 4l70e thats in it. I went with EFI live years ago because it was supposed to be better than hp tunner. I found a friend that says he tunes the tcm in these trailblazers all the time and he is using HP tuners So my question is am I overlooking a way to get into the tcm with efi live or am I gonna have to haul the truck over an hour away to my buddy with hp tunner???
