88 2.5 automatic has started to stall when going into reverse. When I come to a stop, put it in reverse as soon as I release the brake, it stalls. Maybe something electrical? Any help would be appreciated.
Thanks for the replies, but I believe its the tcc switch in the tranny. I unplugged it and I have driven it four times. A lot of start and stop, and reverse and drive and it has not done it at all. I don't feel any difference driving it this way and its only a toy not a daily driver so when I get motivated, I'll change it out. Doesn't look fun!
Patrick, you are absolutely right. About 2 weeks ago it happened about two blocks from the house as I came to a stop. It would start just fine, and I could put it in drive and as soon as I let off the brake it would shudder and die. It did it that night four or five times before I was able to drive off. I may still have a problem but it just hasn't surfaced. I guess we'll see.

Well, you'll still have a "problem" until you replace the TCC solenoid, but with it disconnected you'll at least be able to drive the car. Gas mileage will suffer on the highway, but around town it'll hardly be noticeable.
had a Pontiac once that when you put it in reverse it stalled (automatic) thing was: when put in reverse, the engine "torqued" a little bit, just enough to move the engine so as a bare wire shorted out every time it moved. maybe.....
Your TCC is working correctly*. It is your ECM or wiring is what is failing.
When the TCC fails, it stays locked up. When you release your brake pedal, your TCC is locking up and stalling the engine. That means the TCC is actually working. The brake switch keeps power off of the TCC circuit when depressed. It supplies power only when the brake switch is in the rest position. On the other side of the TCC solenoid the ECM grounds the circuit to activate. So somehow the negative side of your TCC solenoid is getting grounded.
The possibilities - ECM, TCC to ECM wiring, or perhaps by chance the short to ground could be in the TCC itself*.

IThe first time it happened, it was in drive. It took at least four or five tries before it let me drive off. The last time it did it, I came to a stop in front of my driveway, and when I shifted into reverse ( and released the brake) it stalled. I never put it back in drive once I got it in the driveway. Anyway, I've driven it a few times with the tcc unplugged and it hasn't done it since.
