What is the diagnostic code for torque converter clutch?
P0740 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does it mean when a torque converter is not working?
On most vehicles, it indicates that the control module perceives an electrical fault with the torque converter clutch solenoid or the solenoid’s circuit. However, there are some vehicles for which the code is more indicative of a mechanical problem with the transmission or torque converter.
How does a torque converter clutch solenoid work?
A TCC solenoid converts electrical signals to mechanical ones that prompt the converter clutch to engage and disengage appropriately. The opening and closing of the TCC solenoid valve are controlled by the transmission control module (TCM) and a powertrain control module (PCM).
