What happens if you disconnect the torque converter clutch?
But often simply disconnecting the clutch solenoid connector solved the shuddering or stalling condition. Here’s the problem with doing this. The torque converter clutch would no longer apply and the vehicle would get extremely poor fuel economy.
What causes the torque converter to lock in gear?
When the TCC solenoid receives a signal from the engine control module (ECM), it opens a passage in the valve body and hydraulic fluid applies the TCC. When the ECM signal stops, the solenoid closes the valve and pressure is vented, causing the TCC to disengage. This lets the torque converter lock in “gear” or unlock out of “gear.”
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.
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
What causes a GM torque converter to lock up?
Most of the time it is a stuck Torque Converter Clutch (TCC) solenoid, but this is not the only cause of this problem. General Motors has issued a few Technical Service Bulletins (TSBs) relating to this problem. There is also a specific diagnostic procedure to determine the exact cause of the TCC problem.
But often simply disconnecting the clutch solenoid connector solved the shuddering or stalling condition. Here’s the problem with doing this. The torque converter clutch would no longer apply and the vehicle would get extremely poor fuel economy.
Can a damaged torque converter cause the car to stay in gear?
However, a damaged torque converter can cause the car to stay in gear even when the driver has come to a stop. This converter also can lock into direct drive especially if the clutch plate’s friction material has worn away. 4. Faulty Needle Bearings
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.
