Thread: need your help badly trannyman

well if its something to do with my transmission itself wouldnt i have the symptoms no matter what i did? makes no sense that the transmission itself is working perfectly now if there is something wrong with it. its not just going to go away unless it was the pcm. (i did do the big three not even two days ago and had to reset it. which im willing to bet since ive gone wot so many times it didnt give the pcm time to relearn the correct shift points....) please correct me if im wrong.

The PCM adapts to things going on in the tranny. If it detects its slipping it will eventually command higher line pressure to combat the problem, which results in harder shifts.

Resetting the PCM cleared this so the tranny is learning everything again. If the slippage is still there then the tranny will take time to realize it and eventually command higher pressure again. All you did was clear the learned parameters, nothing more. It's relearning.

so is that a bad thing and my problem is going to come back??

It may it may not. That's why everyone was saying we'll have to wait and see.
