What does a clutch solenoid do?
The solenoid moves a valve that sends pressurized fluid to the clutch circuit, engaging the TCC. When the clutch is disengaged, the torque converter allows the engine to rotate without stalling.
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.
Where is the solenoid valve on a torque converter?
Today we’ll be dealing with a Torque Converter Clutch Solenoid Valve. You will see how to locate, remove and test this solenoid valve. 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.
Where is the clutch located in a torque converter?
The clutch is inside the torque converter case; it contains a friction material that locks the turbine shaft to the inside of the torque converter’s shell. It’s controlled by the TCM. It sends a pulsed voltage signal to the TCC solenoid. The solenoid moves a valve that sends pressurized fluid to the clutch circuit, engaging the TCC.
Where do you replace a transmission shift solenoid?
To replace a shift solenoid, you have to remove the transmission fluid pan to reach the faulty solenoid. It is located in the valve body. Warning: In some vehicles, you can’t replace just one solenoid, you have to replace the whole solenoid pack.
How is the torque converter clutch solenoid controlled?
The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the torque converter clutch solenoid. The opening and closing of the TCC solenoid valve is controlled by the transmission control module (TCM) or powertrain control module (PCM), depending on the vehicle.
What happens when the solenoid is disengaged from the clutch?
The solenoid moves a valve that sends pressurized fluid to the clutch circuit, engaging the TCC. When the clutch is disengaged, the torque converter operates normally, allowing the engine to rotate without stalling while the vehicle is slowing and coming to a stop.
Where is the lockup clutch in a transmission converter?
To prevent slipping at certain speeds (normally speeds exceeding 37 mph) a lockup clutch located inside the converter locks the engine’s output drive to the transmission’s input shaft to achieve a 1:1 ratio – meaning 100% of the engine’s power is now reaching the transmission.
Where can I Test my GM GM solenoid convertor?
Most quick methods of testing can be done at the ALDL, which is the plug interface that your factory-like diagnostic tool plugs into. Barring that, the info is still accessible using leads from your test light. This will allow you to do most of the electrical checks from the driver’s seat and save much valuable diagnostic time.
