Some older gm vehicles have a vacuum modulator on the transaxle. If the modulator is faulty, it won't shift. Because of the vacuum it can suck tranny fluid into the throttle-body and it may run down into the air filter, if the modulator diaphram is ruptured. I haven't looked, yet, to see if your transaxle has a vacuum modulator?

Hi, I think I made a mistake on my answer, yesterday. I can't remember what I was drinking? Sorry about that, will try to do better.
