Argh!
I just got another "good news/bad news" call from the transmission shop. Per instructions I gave him yesterday, John (the shop owner) took the car out for another test drive this morning, this time looking to particularly check the functionality of the O/D on/off switch.
The good news is that yesterday (not using the O/D switch) he said that the transmission was shifting fine. Right at the redline under "heavy acceleration" and at the "correct shift points" during normal driving.
When using the O/D switch though, he said the transmission was shifting slower and softer, and he wasn't seeing as much of an RPM difference as he should. When he plugged a scanner to it, he wasn't getting normal pressure readings between those shifts. Further, after only 30 miles' worth of test driving, the fluid is already starting to smell burnt again.
John doesn't want to hand me the car without a clear conscience, so he asked for more time (not charging me any extra) to test the problem. He plans on swapping in a known good '93 transmission and taking that on a test drive to see if the same thing keeps happening. If that's the case, as he suspects, then he says the problem that keeps causing the transmission to fail isn't actually in the transmission. Which makes plenty of sense. Then, he said he'll advise me to take the car to an electrician to get the problem fixed.
What do you guys think now? Could this be the PCM, like suggested earlier in this case? Is there something else that could be the cause?
