If the engine stalls abruptly on your Cirrus, as if some one clamped it, then I would suspect that the 'lock-up' function on the torque converter of the transmission is in the lock-up position. That means it is the same as popping the clutch on a conventional transmission car, which cause the same stall. If you can't drive the car, I would call around to several independent transmission shops to find one that is familiar with the Chrysler 41TE transmission and that appears to be honest. Ask if they have a diagnostic readout box to communicate with the transmission control computer. If they do then have the car towed there and let them try a readout. If they get a code 38 or 0740 (depending upon what year model you have there) then that would show that the lock-up is the problem. If you are lucky the problem will be with a solenoid switch or valve in the box on the side of the transmission which can be corrected easily without removing the transmission. Because this possibility (along with about 6 other causes) is worth pursuing, I would want a shop that is not going to talk you into a "rebuild" without first looking into all the possible reasons for the lock-up condition so you aren't "taken for a ride".
So ask friends if they know a good honest shop and check them out as to how well they understand the Chrysler transmission. You may end up at a Chrysler dealer, but insist on their trying all the other possible causes before authorizing removal of the transmission which is a very expensive repair and may not be necessary.

This could be 1 of 2 Things. Either the Transmission needs Service REALLY Badly or you have a Tooth Broken off of the Gears in the Rear End.

Need help on a 1995 Chevy Suburban. It will die at idle when it's up to running temp and in gear. I have to pump the gas peddle to keep it from dying. Just did a tune up and throttle body cleaning to see...


it sounds like the motor's tick over is far to slow when the car is put in gear if the tick over is say 750 rpm out of gear then it stalls when you put it in gear lift the tick over up to say 850 rpm the best way to set this up is have a friend sit in the car, warm the motor up, then get your friend to hold the foot brake hard on and put the car in gear, if it stalls bring the tick over up (in gear) till it dont stall,,,but hold the brakes hard on when your doing this,,,getting run over is not a nice thing to hapen to you and it wont make your day? you should feel a dit of a thump when you plop it into gear so hold the foot brake down when you do plop it in gear every time you do so, it saves the transmishion getting a thumping, all the things you have done to your car so far have only done it good, but why not change the oil and filter as well and know you have done the full monty on your car, and it wont need another service for another year or so?????

The idle drops when i put it in gear almost stalling the engine


That is normal, in park or neutral there is no resistance on the engine when you put it in gear there is resistance because the car wants to move. Also when you turn on the ac that turns on the compressor that is run off the belts of the engine so it puts more resistance on the engine. Low idle is not a problem unless the engine dies.

You've got to do the obvious things, look at your spark plug wires, if you see what looks like chalky residue they are arcing replace them and your plugs. Check all vacume lines for leaks, and make sure your air filter is clean

1990 Buick stalls when coming to a stop


Sounds like the torque converter clutch solenoid is bad. Unplug it and see if the problem stops. Unplug the 4 wire plug on the front of the transmission.

duck tape on the air intake. I just fixed mine. There is a crack on the intake that lets too much air in when you put it in drive that makes the car stall. Try it it works.
