mkingan Posted September 3, 2013 Report Share Posted September 3, 2013 Hi, i'm getting the P0742 code and it has all the general symptoms of a bad solenoid. i just want to make sure its no a wireing issue before i start tearing this apart since it seems to be a huge job. Anyone know what pin on the wiring harness that goes into the transmission is the TCC? best way to check to make sure its not a wire cut? resistance or ohms ? any help would be great. I was thinking checking the actual pins on the round harness that goes into the transmission. Quote Link to comment Share on other sites More sharing options...
