I'm just looking for some confirmation or some other theories on what is going on this this thing. I've been driving my 91 L67 swapped GP since the 4th of July. It's been shifting super harsh and I keep getting a TCC stuck on code. I realized on Sunday that if I cleared the DTCs that it would run great, nice crisp but not jarring shifts, and the TCC lockup would act normally. After a couple shutdowns and restarts however, the TCC stuck on code would come back as well as the incorrect gear ratio DTC. I've got 3.29 gears and I've set the drive sprocket ratio to 1.000, so I don't understand why I keep getting either of the codes. Anyways, last night I get home, park it on the side of the street for a moment to get the garage open, and when I went to pull it in, I had almost no power being sent to the wheels. It would just slip and creep forward. I found that if I drop the shifter down to 1, that it would engage just fine. Researching the issue, I've read a few times that the issue is probably a slipping or broken forward apply band. Could it be ANYTHING else? Can I confirm it for sure easily?
The really crappy part is that I was planning to finally get it back to the track this weekend. I might just go thrash it this weekend anyways if manually shifting it through gears is just as effective as being in Drive. Will that work? I'm so sick of this damn thing.
