    I'm also having the same problem....is it safe for me to drive the car until i can get it fixed? or should i not drive it? The car runs fine unless its been running for a long period of time. I dont want to mess anything up.

You can try changing the transmission fluid and filter this may free up the TCC solenoid or you might just have to replace the TCC solenoid. When this goes bad you get the problems and issues that you are having. Here is a discussion on the subject that might help you out .... check on recalls for the problem also.

It sounds like the transmision modulator if it is equipped with one. Or the vacuum line running to it.

P0742 torque converter clutch circuit stuck on


Ok, The other day I had a "service Engine Soon" light. The car was shifting really hard, and slamming into each gear. I have found that if I pull over, take my code reader and plug it in, I get a PO742 code. Torque converter circuit stuck on. I proceed to erase that code from the computer, and restart the car and it will run and drive totally fine, as if nothing is wrong. I have been doing it this way for 3 years and the car is running fine to this day. It hasn't cost me a dime in repairs, and I commute 500 miles/week. It's worth a try, because I have heard that if you spend 800-900 bucks to get it "fixed", the problem WILL return some day.

Trouble Code: P0742 This should be looked at by a trusted transmission shop in your area to address this problem. This sometimes does require the replacement of the torque converter itself.

I got an engine light code po 742 what does that mean?


The code means that the Torque Converter Clutch (TCC) in your transmission is staying engaged after the computer has commanded it off. This could be caused by a sticking TCC Solenoid, By internal hydraulic pressure leakage, by a faulty Turbine Speed Sensor Circuit, or a faulty Powertrain Control Module.

If your engine has been stalling when you come to a stop - especially after getting off of the highway, then you probably have a sticking TCC Solenoid.

This really needs to be diagnosed properly to keep from spending a bunch of money on parts unneccessariily.

Car is bucking, engine light on code po742


"Torque converter clutch" solenoid is stuck open which is causing your bucking problems. The solenoid is either disconnected or faulty. if you ran over something, it may have damaged the wiring, but if not, you need to take it in for checkup.

2000 Impala LS, 3800 engine has been 'missing' (intermittently losing acceleration in quick succession) when temp is at or over half way to 'hot' on temp gauge. That's usually after about 30 minutes on...


you sure its missing and not a torque converter shudder . as a auto tech some times its hard for me to tell the difference. it it was missing it would throw a miss fire code not a torque converter code at 126 k sounds the the trans needs to come out and a good tech needs to rebuild it
