92 Lumina Euro Stalling help

I need some advice from some of you who know more about these cars than I do. I have read quite a few threads here relating to the problem I have, but am still not sure where to go from here.

Recently I had the transmission replaced on my 92 Lumina. After it was replaced it would die when coming to a stop after the car was warm. It actually showed all of the classic signs of the TCC solenoid. The mechanic who replaced the transmission (with a rebuilt one) replaced it being the most logical choice as well as reciveing an error code for it.

Well, needless to say, this did not fix the problem. Is there anything else that can cause the same symptoms as the TCC solenoid sticking?
Here is a quick rundown of those symptoms.

Car dies when coming to a top after about 10 minuets of driving. It will start right up again, but die once it is put into gear. If you give a good amount of gas while you put it in gear it will hesitantly start to go (trying to stall out again at first).

After the car sits for about 10 minuets it will go again without a problem until the next stop.

After car fully cools down (1-2 hours) it is good to go again for abotu another 10-20 minuets.

Once again, the TCC solenoid has been replaced and no further codes come up on the scanner. Any help would be greatly appriciated. This did not start until the transmission was replaced so I am fairly certain it has something to do with that.

Thanks in advance for any help.

Classic sympton of a TCC solenoid. I know of nothing else that can cause this, but perhaps someone else will. One thing to try is to unhook the solenoid and drive it for a while and see if that stops the stalling. If it does then you have an issue with transmission folks. I think there is a problem unhooking if you have a 4 speed trans. but should be oK os a 3 speed. If indoubt ask the company that installed it. Only way I know to rule it out.(they don't always set a code when bad, and dirty fluid can cause as well.)Of course you have a rebuilt one, so that should not be an issue (unless they did not flush the lines).

OK. Here's the deal. With a defective TCC, that's bad enough to kill the motor, what happens is it will struggle and "fight" the brakes, just as if you were driving a stick and forgot to push the clutch in (because that is essentially what's happening). As you stop, the motor dies, rather abruptly. Once in park or nuetral, the motor will restart normally, but will be killed very harshly as soon as any attempt to put it in gear happens. After a period of minutes to hours, the pressure in the TCC mechanism bleeds off, releasing lock-up, and the car functions normally, until temp and load conditions allow lock-up , and the problem repeats.

If you are able to put it in gear and feather the throttle and make it go, I doubt the TCC is the culprit. Howwever, you might ask if the torque convertor was replaced when the tranny was done. Sometimes the old one is re-used, unless you specify. What you are describing sounds more like a bad Crank Position Sensor, or ignition module to me. Maybe even a fuel pump, but that is less likely. You need to carry a spark plug with you, when it has problems, pull a wire and put that one in it, have someone crank the motor while you ground the plug on the engine, and see if you got strong, crisp blue spark, or weak yellow-orange or no spark at all. If that's the case, I'd look at the ignition components I described. If the spark seems good, see if AutoZone or someplace will rent you a fuel pressure gauge, so you can see what kinda pressure you've got when it occurs.

Like jsgold said, if you can disable that TCC, that would be the easiest way to rule that in or out. Some years had a fuse for the TCC, check your fusebox before trying to disconnect the harness.

Thanks for the suggestions. I am going to unhook the TCC this weekend and see what happens. I have a few more questions.

When I said if you give a good amount of gas while you put it in gear it will hesitantly start to go, what it feels like is trying to start out in second gear on a manual transmission from a dead stop. It bogs down and hesitates wuite a bit. If the problem is not the TCC could the actual torque converter itself going out cause the same problems? I am almost 100% certain they did not replace it when they did the transmission. This worries me now that I think about it. Basically my wife ran the old one out of fluid and burned it up. What if they didn't even bother to flush the fluid out of it?

If it might be the Crank position sensor, would it start back up immediatley after it dies and then only die again once put into gear?

I am going to bring it in to my regular mechanic on Monday and want to load him up with all the info I have. Maybe between the 2 of us we can figure it out. The guys who replaced the Transmission tried to tell my wife it was either a bad sparkplug or bad wire. To me that just did not sound right. Anyhow I am going to have him hook of the scope and see what he can find.

Thanks again for the suggestions.

It could be the lockup dragging. most I've dealt with were locked so solidly, that even if you held the engine at three or four thousand RPM's it would stop dead as soon as you tried to put it in gear. It's possible that yours is not quite fully locked, but hanging up enough to cause what you describe. Trying to drive from a stop with the convertor even partially locked would put a lot of load on it. Hopefully, it is something else. If you were dragging the lockup, but not actually fully locking, I'd think the mechanism was so far gone that there would probably be a lot of debris in the tranny by now from it.

Just for laughs, try carrying a small hammer with you, and give the EGR valve a good knock wwhen it does that. See what happens.

tcc solenoid needs unplugged , try this,if this doesnt fix the problem try changing tpc sensor on carb,im sure unplugging the tcc will fix your problem

Could be the IAC motor sticking open, acting as a uge vacuum leak. Try disconnecting this before you start it and take it on a test drive. The "check engine" light may illuminate. If on your test drive it drives normally, replace the IAC motor, and disconnect the battery to reset the ECM.
