What do you mean it is stuck in the on position? A torque converter uses fluid dynamics, there is no switch.

    I would look into where the location of the solenoid is, I always recommend getting a repair guide for your vehicle when you purchase it, very valuable tool. Autozone has free repair manuals available online. Chances are you'll be replacing this solenoid, and as long as you don't have to mess with the valve body, you should be ok. It can get quite challenging if you need to dig further.

SOURCE: torque converter clutch solenoid stuck

Unless you live in a state that requires an emissions test, forget it. The factory fix is to replaced the converter and internal seals and bushings. These states machines will not let you run a test with the light on.

SOURCE: Torque Converter Clutch Circuit Stuck On

the torque converter clutch circuit is inside the torque converter and is not something u can repair, the torque converter must be cut apart and rebuilt by companies who specialize in this, so all you can do is pull the transmission out of the car and replace the torque converter with a rebuilt or new unit.

Sounds like they put a defective converter in your car..they do sell a converter oil additive to handle coverter lock up problems that may take care of it..check with the trans garage about trying it. Or go for the warrenty if valid still..good luck.

Shifter wont shift


Hi there:
When you say it will not shift into gear, do you mean the shifter doesn't move out of the park position or the shifter moves into the gear ranges but the trans doesn't engage and move the car.



First I suggest checked the fluid level, is it full or low or maybe high, check it with the engine running,


Could be a problem with the torque converter or valve solenoids.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

did you hook up the flywheel to the torque converter? the clicking and grinding noise could be the trans is in park and the flywheel is going around, or the torque converter is bound up and not properly in the pump of the trans, and the clicking and grinding could be the parking pawl trying to stop and lock the trans.(this is what stops the car from rolling) I think its a torque converter alignment problem.

1999 Buick Park Ave Ultra Service Engine Light Code #P0742


The code PO742 indicates the torque converter clutch is stuck on.
The torque converter is what connects the engine to the transmission.
It engages and disengages according to signals from the pcm, to aid in
smooth shifting. There are a couple of things you can try. make sure trans. fluid is full, if thats ok check the 20 pin connector, located on left
side of car on top of transmission bell housing. Make sure there's no
corrosion or bent pins. If this clears the code your all set, if not you may
want to ask your mechanic and see what he/she recomends.
Hope this helps.
Good luck

Need to know what the trouble code numbers are


P0743 is the Torque Converter Circuit Solenoid.The solenoid plug is on the front of the transmission and has a dark green/white and orange/black wire. The dark green/white should have 12V on it from fuse #10 when the ignition is on. The orange/black is a grounding wire from pin 79 of the powertrain controller which should only be grounded when the car is going over 45 mph or so. You could check that the wire is patent between the plug and the powertrain plug (near 0 ohms). The solenoid is a coil or wire so it would have a low, but non-0 resistance, maybe less than an ohm, but still not 0. To really test it you would need an impedence meter, but a good digital ohmmeter should show it to be slightly more resistance than is shown when you test the resistance of the meter leads themselves.If the resistance, the patency, and the 12V supply is all shown to be OK, then I would suspect the solenoid is not functing properly. If you are getting torque converter lock up when you accelerate slowly from 40 to 50 mph then it is working and the code is false. P1899 Park or neutral position switch stuck in park or gear. Recap: P0743 Torque converter clutch circuit faulty, P1899 Position switch to park and nutral stuck. Check the wire harness and look for any clips may be lose or disconnected and wires condition. Good luck and keep me posted. be glad to help
