engine code is reading P0743

please epost only part of your question made it through. thenks

I Have An 01 F 350 7.3 L That Reconnected The Wire Harness Under Driver Side Valve Cover. When Started Up Everything ran fine. when i went to drive it, it stalled out pulling the code P0743. there is a big harness connection above the valve cover that i did not take apart but moved around a lot to get the cover off. i do not see any bare wires but i cannot get it apart to look for corrosion inside the connection. am i on the right track and how do i get the connection appart

P0743 – Torque Converter Clutch Circuit Electrical
normally the prob is the harness inside the valve cover.trying to find harness connector no luck yet .i will send as soon as i locate .

i reconnected the the harness connector on the gasket of the valve cover. are you thinking the tcc is tied into that as well

well i really ca't see where it would be connected.but if you reconnected plug and ran ok then stopped running possibly plug has come off or harness inside v/c is bad this is a common prob. however should have a misfire code as well.

the engine runs fine sitting there in park. when i go to shift into gear it stalls and i cannot move it. i believe this is because of the P0743 code i just don't know if the tcc electrical is tied into the main harness connection above the valve cover
