I just bought a 2007 TBSS with a 4L80e swap already done. It has a PCM of NC harness and the TCM was already tuned going by their instructions. Trans is in limp mode. I do not care to repin the harness for a 4L80e if I can find the correct TCM. I am assuming I need to find a TCM from a 2007 Express/Savannah for this to work correctly. Any and all info is appreciated.
