How to repair a torque converter clutch circuit?
1 Replacing the torque converter lockup solenoid 2 Replacing the TCC solenoid 3 Repairing damaged wiring to TCC solenoid 4 Replacing the valve body 5 Replacing the TCM 6 Repairing damaged wiring to the transmission wiring harness 7 Replacing ECT sensor 8 In some cases, the transmission itself will need to be replaced or rebuilt
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.
Can a faulty torque converter cause rough acceleration?
If the torque converter is locked in the drive or idling gear and does not release the transmission, you most likely have a problem with the converter clutch. A faulty torque converter clutch can also cause other symptoms such as slipping and rough acceleration. 4. Faulty Torque Converter Clutch Solenoid
Where is the clutch solenoid valve on an automatic transmission?
The torque converter on an automatic transmission transmits engine torque and power to the transmission. To prevent slippage a lockup clutch is located inside the converter. Simplistically, the clutch solenoid valve controls fluid pressure that is applied and released to the lockup clutch.
What is the code for torque converter clutch solenoid?
Code P0740 indicates that the control module detects an electrical problem with the torque converter clutch solenoid or the solenoid’s circuit. Note: Although code P0740 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may vary depending on the vehicle manufacturer.
Is it possible to repair a torque converter clutch?
Some customers would try to avoid the repair which includes replacing the torque converter clutch solenoid. This part mounts in the valve body. However, after several months of receiving very poor fuel economy they would usually come back and have the operation performed.
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.
The torque converter on an automatic transmission transmits engine torque and power to the transmission. To prevent slippage a lockup clutch is located inside the converter. Simplistically, the clutch solenoid valve controls fluid pressure that is applied and released to the lockup clutch.
