Hello, i recently tuned a truck and i cant get the lock-up to work. 04 Silverado and we did a 6.2 and 4l80e swap to it. First we just swapped in the 6.2 and everything worked great. Later swapped the 4l80e to it and lock-up hasnt worked since then. I can get it to lock but only if i manually engage it in the scanner. I left all the stock values for tcc in the pcm from what the 4l80e segment had, just increased tcc duty cycle. i will attach the tune. Still needs some work but i would like to fix this first.
