Hi all. I've got an odd transmission problem. Haven't found it listed (no guarantee I didn't miss it, of course).
Car is a '91 Talon AWD 5 spd. Totally stock. About 170k miles. San Jose, CA area. (Milpitas, actually.)
Trans made a slight whine/howl going down the freeway. Got home, pulled the end cover off the trans, since it had that "move in 5th gear shifter wiggle", and I thought it might have a nut touching the inside cover. No such luck. Both nuts were slightly loose, but what got my attention was the intermediate shaft(?) (the middle one) was wobbly. I could see that the back of that gear was shaving aluminum from the inner case surface. Tightening up the nuts didn't help. Re-installed the cover to move the car so I could work on my truck.
Months later, I decided to see if the bearing could be replaced, having read that it could be done without yanking the trans out. Turns out the bearing isn't the problem, near as I can tell. Pulled the gear and other stuff off the shafts, and could see that the tapered roller bearing looked ok, so no reason to pull the inner case.
The problem appears to be the failure of whatever holds the shaft from shifting end to end. I've looked at the photos I can find, but still haven't figured out what could have enabled so much free play (1/8 inch, maybe). Snap ring, thrust washer, shims broken? No idea. Anyway that trans will have to come apart, and I'm not going to bother.
------------------------ ++++++++++++++++ --------------------------------
However, when I tried to replace the parts so I could move the car again, I discovered I have no neutral. Shifter wouldn't go into the 5th/rev gate, and it is in gear, although I have no idea which gear. Pulled the cover back off, and played with the shifter fork setup for rev/5th, but cannot get neutral. Even with the shifter indicating neutral, the trans is still in a gear, or even two, perhaps.
I DO NOT have time to screw with this car right now. My truck has a problem that has to be resolved NOW. The car HAS to move out of the driveway. Any suggestions/assistance?
