hey guys. been doing a lot of reading on here since i got this expedition. had it for almost a year now and still dont have it on the road. on problem after the next haha. a little back info - doing alot of body work... the rockers where gone. so bad that the inner rocker and parts of the floor had pretty bad holes. only a couple small ones between the seats and rockers. well last fall when i was welding in patch pieces i went to move it and it stalls in all the forward gears but reverse is fine. im assuming the problem stems from the welding. but besides following all the harnesses and wires how can i check the TCC (without dropping the pan) just dont have the money right yet to start throwing parts it. i checked this monring and im having a hard time finding the trans harness. couldnt find much info on pin outs or anything for the expedition. and the haynes manual doesnt say anything about it. OD Off light is on solid (not flashing) and im getting one code P0743 - Torque Convertor Clutch Circuit Electrical

any help is much appreciated!
