What's wrong with my tranny?

What's wrong with my tranny?
The car is an auto 90 gxe with 174k. The problems started at around 170k. At first it had serious problems going in reverse and idled roughly. Took it in to our regular mechanic and he said it needed a rebuild, but for $2500. Said no way, took it back and the problem magically disappeared. Through the next couple thousand miles the problems came back and went away, including 1st gear not catching when first put into drive.
Now the problem is that it stalls out when I come to a stop. If I put it in neutral before I stop the engine won't stall but I have to give it some gas before going back into Drive so I get treated with a lovely forceful jerk. This problem of course also goes away and comes back when it wants to.
So has anyone else had these problems and is a full rebuild the only solution? I took it to Cottman's last weekend and they said they couldn't find anything wrong with it, they even held it a day extra to retest it after I explained the symptons. Again nothing found.
One mechanic I talked to said it might just be a bad sensor, could this possibly (and hopefully) be true? Thanks for any help.

Doesn't sound like a transmission problem, at least to me.
Time to break out a multimeter and factory service manual and test a couple of components such as the mass air sensor, throttle position sensor, fuel injectors, auxiliary air control. etc etc etc. If you know how to work a multimeter you can save yourself alot of money by disgnosing the problem yourself, the factory service manual outlines the procedure to test each of these components.
BTW, in the meantime, avoid putting the car into drive while giving it gas, at 170K i would be pampering it as much as possible, not hearing it go THUD!
good luck.

Well, from what I read, if you do actually have tranny woes, your car dies because there's something wrong with the overdrive sensor (if you leave O/D off when you do city driving).
What I have learned is that your OD sensor is not kicking the tranny out of OD when you are coming to a stop and reaching a stop. It's much like how a manual transmission would kill the engine when the driver leaves the engine in 5th gear and then coming to a stop, without depressing the clutch.
Maybe not much help, but might give you an idea to what's goin' on down there so when you approach the mechanic, you won't end up purchasing a rebuilt engine, tranny, and whatever might NOT be wrong.
Good luck.
