Hello everyone new here..Got a question hoping for some answers.i have a 95 Dodge neon SOHC with Auto trans.We just got finished with a motor Swap in it and im noticing the Check engine light on with the Error Code P0743 (Torque Converter electrical Circuit Malfunction) i do have a problem with the car i am trying to solve in the meantime..(I think the Cat is Clogged) But im trying to get Everything Solved..Is there a Solution to this..Where would i start looking?this code wasnt on before the Swap..even tho the Car runs like **** with the Cat being Clogged.(lack of power) it doesnt seem to be Slipping or anything.Anyone got any Suggestions for me to get this Light to go off?lol thanks guys

 

maybe doing the swapp, you cut a wire! check out the wiring!

 

that is not the case.We installed a Brand new Harness while doing the Swap so i know there are No cut Wires and all the plugs to the Tranny appear to be Clean..Is there a Sensor to replace?im just trying to solve this Check engine light...haven't found any Details things about this issue..

My best advise is to check the Torque Converter Clutch (TCC) Solenoid, if you want more in depth detail go to Mitchell 1, it only cost $25. for a year less for a few months. Good luck
