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.
What are the symptoms of a p0740 DTC?
If any additional transmission related DTC’s appear in addition to the P0740, an electrical failure is likely. Symptoms of a P0740 trouble code may include: Malfunction Indicator Lamp (MIL) illuminated (a.k.a. Check Engine Light) Minimal decrease in fuel economy, this will not affect engine performance Causes of this DTC may include:
What happens when the p0740 code is stored?
If the circuit to this solenoid fails, the p0740 code may be stored. The most common problem you will notice when the P0740 appears is a check engine light or gearbox light on your dashboard. You will most often not have any shifting or drivability problems, but it can be noticeable in some cases.
What does the DTC code p0740 stand for?
What Does the P0740 Code Mean? Diagnostic trouble code (DTC) P0740 stands for “Torque Converter Clutch Solenoid Circuit/Open Circuit Malfunction.” On most vehicles, it indicates that the control module perceives an electrical fault with the torque converter clutch solenoid or the solenoid’s circuit.
What happens when torque converter code p0740 is triggered?
You may experience shifting problems when code P0740 is triggered. If the TCC is stuck on, it may cause the vehicle to stall when coming to a stop. A TCC that isn’t engaging/disengaging properly can cause a shudder that’s felt at certain speeds. Failing to engage the torque converter clutch results in slippage that reduces fuel mileage.
When does the solenoid set the p0740 code?
On most vehicles, the module will set a P0740 code when it detects an electrical fault with the TCC solenoid or the TCC control circuit. Also, as was mentioned, on some vehicles, the code may set when the TCC’s performance is out of range due to a mechanical problem.

Why does the p0740 have a torque converter clutch?
The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine. In effect, this allows an automatic transmission to function like a manual transmission at certain speeds and engine loads, and eliminates all slipping from the transmission. The symptoms of P0740 vary greatly.
What does code p0740 indicate?
