Has the trans been serviced? Could be the lockup is gummed up with old transmission fluid. tends to turn into a gummy varnish if the transmission isnt serviced but i dont recommend going to a shop to have it serviced if it has more than 200,000 or more on it by then its better to do maintnance by changing the fluid and the filter in the pan

I have a 1993 Chevy WT1500 pickup with a leaking transmission.


did you use lock tight on the torque converter bolts when installing them? it may be coming loose and ruining the seals. It doesn't take much. You may have some kind of buildup on your output shaft or a bur of some type that is cutting the seal. Check the outside hub of the torque conv. for roughness or spurs. The seals should work if everything is done right.

Engine dies in drive and reverse


I can't say for sure, but one possible problem is a locked up torque converter in the transmission bell housing. If the torque converter is locked up then the engine can't turn freely when the vehicle is in gear.

Yellow check engine light came on; code; P0741 refers to possible torque converter problem. car runs fine. what else could it be?


Audi code P0741 Torque Converter Clutch Circuit Performance or Stuck Off, THIS IS IN MOST CASES A STUCK TORQUE CONVERTER LOCK UP CLUTCH, U MAY NOT EVEN NOTICE THIS AS ALL GEARS WILL WORK JUST NO TORQUE CONVERTER LOCK UP, U WILL NEED TO VERIFY THE TORQUE CONVERTER CLUTCH CIRCUIT IS OK AND IF SO REPLACE THE TRANSMISSION TORQUE CONVERTER.

Transmission wont go into gear after starting car


I have never heard of a problem this extreme. Here are two ideas to try. First, the torque converter is separate from the transmission, but acts like a pump. The torque converter has to lockup in order to turn the transmission shaft. This means if the torque converter does not work your car will not move right. There are pressure adjustments on some automatics which can only be set by someone with the right tools. Last, I think it would take a lot more than the wrong fluid in the car to make this much difference. But make sure the correct fluid is in the car. Good luck

1994 mazda cronos 2.00 v6 auto car idles ok drives ok but when i come to a stop it stalls in gear been atuo


This sounds like a problem with the torque converter lockup system. Usually the torque converter lockup solenoid is at fault in your condition. This solenoid usually locks up the torque convertor (which acts like a clutch in an automatic transmission) when you are driving at a certain speed, and unlocks it when you press the brake, and/or come to a stop. When a torque converter stays locked up, and you stop the vehicle, it acts like a vehicle with a manual transmission, if you bring the vehicle to a complete stop without applying the clutch pedal, the brakes stall the engine. Basically, if the torque converter can't unlock, even when you come to a stop, the engine is still locked to the transmission, and even when you apply the brakes, the torque converter doesn't slip and freewheel like it should, but instead stalls the engine.
