Hello everyone,
I'm having a problem. I have a 1999 Grand Prix GT (not supercharge) and I get the code P0742 (car shakes also) whenever I drive my car for over 20 min. or go over 50mph, which sucks. I understand that the code means that I have to replace my tcc solenoid but I can't seem to find it. Does anyone know where it is? I've tried looking for pics or anything that can help me but I couldn't find anything. Please help.
