I got the code that was given when my trans was shifting erratically. The code was PO742. Anyone know what that code is? Thanks

Thank you very much. I appreciate the help.

I took my HHR to a Chevy dealer today with the results of having the code read. The tech said it wasn’t the torque converter clutch solenoid, it was actually the converter itself. He called it torque converter shutter. Is he blowing smoke up my butt or is he right?

You can find additives to help with shudder.

Hmm, I don’t se torque converter listed in probable causes, I do see TCC solenoid , change the shift solenoids while you’re in there
