I thought GM changed the TC lockup to PWM around 96-97. I have a 97, and want to use a PCM from a 96 temporarily. Will it work OK?

: Any difference between 96 and 97? thefermanator 01-13-2006, 12:15 AM I'm assuming when you say PWM you mean pulse width modulating, if so my 95 has it. So you should be able to make the swap. Mnay in the 6.5 section do it when switching from S to F PCM's. jac6695 01-13-2006, 07:18 PM I thought so too. I know on the 4L60E the switch to PWM was around 96-97, so I wasn't sure about the 4L80E. Thanks for the info! thefermanator 01-14-2006, 01:29 AM Most of the upgrades to the 4L80's were in mid 93. | ||
