If you know that the torque converter is actually working correctly, I would unhook the battery which will then erase the memory on your computer diagnostic codes and re-check. If the code does not pop back up again when you try to diagnose any engine problems, you have reset the computer, it will also indicate that the torque converter is fine and all you did was pull up a faulty code.

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.
