New to this forum. Also looking to tune a 6L80 and trying to work out all the issues in my transmission swap. I have a 6.2 diesel (1983) and have removed the TH-400 and about to put in a 6L80 with a TCM-2600 interface and don't have a clue what I doing after that. Did you (Leatherneck/RAV3) get your slip resolved? I too hate to spend that kind of money on a tuner that hopefully I will not need too many times although from what steelerdude15 added about the HP Tuner being great for diagnostics would be a plus. I am also from WNC but below you in Columbus. Any helo would be greatly appreciated.
