What is the code for torque converter clutch?
A P0740 OBD-II code is a generic trouble code that is supported by many cars. But while this diagnostic code can appear on a variety of vehicles, the steps for diagnosis and repair may vary depending on the vehicle’s make and model. The torque converter clutch creates a mechanical connection between the engine and transmission.
Is there a problem with the torque converter clutch solenoid?
The most common mistake of the P0740 is to think there is a problem with the torque converter itself and maybe replace it. 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.
What does lock up clutch do on Honda?
Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
How is the lockup converter clutch assembly controlled?
The lockup converter clutch assembly is controlled by the engine computer or transmission control module depending on the model and the year of the vehicle. The control module energizes the relay which then sends 12 V to the lockup solenoid.
What does a torque converter clutch do on a Honda Accord?
It means that the Accord ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.

What causes a torque converter clutch code p0740?
To fix the P0740 code, you need to diagnose a faulty converter clutch solenoid or a wiring issue causing the problem. To do so, you can follow our diagnosis guide in this article. What causes code P0740?
What are the symptoms of a torque converter problem?
Common symptoms include: Check engine light illuminates. Drop in Fuel Economy. Torque Converter Clutch fails to engage. Trouble when shifting Gears. Transmission overheating.
How does the torque converter work in a car?
The torque converter is a fluid coupling that transfers (and multiplies) rotational force from the engine to the transmission. Also, to prevent stalling when the vehicle is at a standstill, the torque converter acts as a clutch between the engine and transmission.
What’s the diagnostic code for a torque converter clutch?
P0741 OBD-II Trouble Code: Torque Converter Clutch Circuit Performance or Stuck Off. Cost of diagnosing the P0741 code. P0741 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Performance or Stuck Off”.
The torque converter is a fluid coupling that transfers (and multiplies) rotational force from the engine to the transmission. Also, to prevent stalling when the vehicle is at a standstill, the torque converter acts as a clutch between the engine and transmission.
Common symptoms include: Check engine light illuminates. Drop in Fuel Economy. Torque Converter Clutch fails to engage. Trouble when shifting Gears. Transmission overheating.
Where is the torque converter clutch solenoid circuit located?
At certain speeds, the torque converter clutch (located inside the converter) creates a mechanical connection between the engine and transmission. The control module operates the TCC via one or more solenoid valves. Applying the TCC improves fuel economy, reduces engine speed, and lowers the temperature of the transmission fluid.
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 p0740 mean on a VW Jetta?
P0740 is one of the most common transmission trouble codes. It means that the Jetta ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.
Where is the torque converter in a car?
The torque converter is located between the rear of the engine and the front of the automatic transmission. Inside this device is the torque converter clutch (TCC)—a component made up of a friction material that locks the converter shell onto the turbine shaft.
