What does the TCC do?

The (TCC) torque converter clutch creates a one-to-one connection between the engine and the transmission that increases fuel mileage and reduces transmission fluid temperatures. When the clutch is disengaged, the torque converter allows the engine to rotate without stalling.

What is a TCC circuit malfunction?

P0740: Torque Converter Clutch Circuit Malfunction OBD-II Trouble Code. The presence of a P0740 DTC means that the ECU has detected a problem in the circuit that controls the torque convertor clutch solenoid. A torque converter clutch (TCC) circuit malfunction is what triggers trouble code P0740.

What does TCC out of range mean?

Which means that the Torque Converter Clutch (TCC) is disengaged or the EPC pressure is at the minimum. The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.

What is a TCC circuit?

The torque converter is located between the rear of the engine and the front of the 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.

What is the purpose of a TCC solenoid?

There is a solenoid in your GM converter that causes the the torque convertor clutch (TCC) to engage and disengage. 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.

What is a TCC solenoid?

Transmission Torque Converter Clutch (TCC) Solenoid: DESCRIPTION. Positioned between the rear of the engine and the front of the transmission is the torque converter. The torque converter is responsible for transmitting the engine’s torque and power to the transmission.

How do you test for TCC?

Placement tests are free, and you can take them on any TCC campus. Tests are currently administered by appointment only. Appointments must be made 48 hours in advance. Email [email protected] or call 757-822-2194.
