This is and LT1 engine running a LS1 computer, but I drove the car before the conversion with the TCI box (shifted fine). I swaped TQ converters and controllers and when I took it down the road today for the first time in a long time it doesn't shift.
Could it possibly be in my tune. I also want to add manually putting it into first to second does not shift either.
ANYONE care to take a look, I can get additional data.
