1997 Neon trouble code P0743???

Does anyone know what the trouble code P0743-Tourque converter circuit electrical means and what are the common problelms that couse this?

Thank you

I am guessing: I think it means the PCM (the brain) doesnt sense any current in the circuit for 'torque converter lockup'. This 'lockup' would happen when you are in high gear and going above about 45 mph. It could be a connector is loose, a wire broken, or shorted. Its not easy to poke around in the wiring harnesses going to the transmission - but if you can, wiggle and reseat each connector. Also wiggle and push in on the connectors going into the PCM next to the battery. Make sure they are fully 'clipped on'. There is probably a connector inside the transmission too - but its not reachable without dismantling things, and its unlikely it would come fail. There is a computer controlled solenoid inside the tranny, which is what causes the torque conveter to lockup.
On the bright side, if your torque converter is not locking up - you can drive the car indefinitely that way. Your MPG will suffer a few percent - maybe 5%-7%. But it wont hurt the car.
