Hello everyone,
I am new to this forum. I figured that since i am using HPtuners MPVI2 this would be the best place to get some insight. I recently took out the 6L80e from my 2014 SS Supercharged Camaro and put a new 4L80e using the harness and TCM from PCM of NC which made the swap a breeze. Although the engine runs great and the transmission also while in motion; it seems like the TCC is not releasing when i come to a stop. The problem is only when at operating temperatures. When the vehicle is cold, everything is fine. Once temperatures rise, and i place the transmission on reverse or driver it stalls after about 10 or so seconds. If i am driving, then it does it when i come to a stop. I have been playing with the different setting with minimal results and although the staff at PCM of NC have been great assisting me, i wanted to see if anyone out there has had the same issues and possibly a fix. I am attaching the tune that is on there as of today. Any help is appreciated, thank you.
