P0743 code


Code 743 is for the torque converter circuit.
The problem could be the torque converter itself or the wiring-solenoid going to it.

Code 743 means the computer did a volt drop test on the circuit and found the solenoid to be open or shorted to ground. It could be the solenoid valve, or the wiring.

Code 743 is for a problem with the torque converter clutch or circuit, and code 745 is for a problem with the pressure control solenoid.
Those two components are inside the transmission and would need to be tested by someone with the necessary tools and repair procedures.

I have a error code reading of PO 743, Torque converter clutch, what does that mean?


It sounds like the convertor in the exhaust system is partly blocked. You will need to have this checked at a shop. Frankster016
