Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The P0741 means the torque converter clutch is not locking when commanded.
The solenoid that allows fluid pressure to the converter would be my choice before the converter is replaced unless pressure tests have been performed.
The cost is certainly less than $7000 if you don't need to replace the transmission.
The point of the P0741 is to flag a potential emission issues, if the converter does not lock about 45 mph then it slips a bit and lowers fuel mileage a bit.
If you can get past the emission test then you do not need this repaired but it sounds like you have an emissions test to pass so you can register?
Yes you should have this diagnosed at an independent shop that has a Hyundai scantool. They should be looking at the control circuit for the torque converter lockup. It has 12 volts through a fuse, the solenoid that controls the application of hydraulic pressure to the converter and the ground side which is controlled out of the powertrain computer.
I doubt you need a whole transmission to get the light out and this code to clear.
Please let me know how I can help
