I have an issue with the converter unlocking @ about 50 mph. It will stay unlocked for a few minutes with cruise on and lock back up. Seems to do it most @ about 50mph. I have tcc set to lock up @ 40 in 4th and unlock @ 38 in 4th (4.11 gears). I have all of the updates to the valvebody that comes in the Transgo HD2 kit and the converter is a vig3600. I think that the kit does away with the Pulse Width (not sure). Are there any values that I can change to the PWM to keep it locked when it locks. No SES or PO1870 codes. Misfire tables have been raised and logged to see that they aren't exceeded.
