After a year with 15lbs on of boost and e85 trans let go. I went through trans completely building it. Then right after for the longest Id been burning up 4,5,6 and hurting the other clutches on 1st drive after my build. Performed resets per previous thread and nothing. No codes in tcm or pcm. Flashed original stock file and still flary and slips. Stock tune was 3 times better, to give a perspective way before trans gave out. No tune or adjustment was made for a while before this problem occured out of the blue. Decided that tuning was not the problem and tuning was not going to fix the problem, meaning I had gone with minor changes to major changes in tune and nothing. I had a 6l80e trasmission from I believe was a tahoe. Pulled tcm and installed onto my trans with no tune yet and drove awesome. TCM seems to of been the problem, but my new problem is I have no sport or tutd mode. Ive enabled tutd mode in trans tune (D9602) and in trans diagnostics Ive used all g8 enablers and still no sport or tutd. Is there a way to do a full reflash of tcm from a g8 with efilive to the tahoe tcm or is it even possible. Any help be greatly appreciated. Hope this info helps also for anybody else that might have a freak of a problem like mine.
