So ive been having tcc lockup issues it just wont lock and if it does its extremely rare. So the other day i was driving with a code readed and i hit erase codes though i had no codes no pending and it locked as soon as it said erase done. It stayed locked till i let off, then wouldnt lock again...
Brand new here hopefully im not in the wrong spot. Hopfully you guys can shed some light on my issues.
Ive got and 06 2500hd with the 4l80e. Started out the tcc was unlocking on the highway as time went on it got more frequent until it just never locked up again? also i notices when in tow mode...
