I reactivated my HPT account and dug my interface out. After hours of uploading all the updated software on the shop laptop (slow as hell) I was able to start looking at the car. The tranny tune is not stock, but nothing changed that would cause this issue. I did however save a stock tune I found in the repository for comparison and trouble shooting.
While datalogging on the way to work I was able to command the TCC sol on and off and it was acutally doing the opposite of commanded. I commanded "off" and the thing locked up and drove normal. For giggles I left it commanded "off" and the car drove right everywhere, even at stops and such locking and unlocking as it should. This leads me to almost believe its electrical. I can't see how a mech problem would cause this. Maybe the harness is fried?
So a few miles from work I unplugged HPT and the car continued to drive correctly. Wierd. I then made sure It somehow didn't command "off" permanently, which I think is impossible, and it showed no command. I then noticed that the 1-2 shift was much harsher. Light throttle would chip tires. Parked and I have not re-strted to see if the change was permanent. Driving me nuts. At this point I would be happy if it stuck and the chirping shifts don't tear the rear or tranny up. At least I can drive on a highway.
