What does a torque converter code mean?
What does a torque converter code mean?
What the P0740 code means is that the powertrain control module (PCM) has detected something unusual within the torque converter clutch circuit. If the torque converter clutch application is abnormal (usually multiple times) the powertrain control module will trigger a Check Engine Light.
What does the code p0740 mean on a torque converter?
The p0740 code clearly states a problem with the electrical circuit to the torque converter clutch solenoid and not a problem with the torque converter itself. Diagnosing the P0740 is often pretty straightforward. You need to find some measure values for your specific car and transmission model, though.
When do I get the trouble code on my torque converter?

Common symptoms include: The P0740 trouble code can be triggered due to many reasons.
What does the p0740 code on a torque converter mean?
What the P0740 code means. What the P0740 code means is that the powertrain control module (PCM) has detected something unusual within the torque converter clutch circuit. The powertrain control module can vary the application of the torque converter clutch for optimal vehicle performance.
What is the trouble code for a torque converter?
P0740 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Malfunction”.
