How is the torque converter clutch pressure control?
P2757 Toyota Description The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled.
Where is the p2762 code on a torque converter clutch?
If the P2762 code returns, you may want to check the resistance of the TCC pressure control solenoid. With the ignition switch in the off position, disconnect the electrical connector at the pressure control solenoid. Locate the 2 pins that go to the pressure control solenoid.
How many quarts of torque converter clutch solenoid?
You will need between 3 and 5 quarts. A failed transmission solenoid or an open circuit anywhere in the electrical system may cause the transmission to go into Fail Safe (or “limp” mode as it is also called) in order to protect the transmission from internal damage that might be caused by the faulty solenoid or open circuit.
What happens when the torque converter goes bad?
Since the clutch locks the engine and the transmission into a direct drive, as a result, a bad clutch can become unpredictable when locking the transmission and engine. The torque converter clutch solenoid measures the pressure of the transmission fluid.

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 do I need to lock up the torque converter?
The TCC System uses a solenoid-operated valve to couple the engine flywheel to the output shaft of the transmission through the torque converter. Lockup reduces slippage in the converter increasing fuel economy. For the converter clutch to apply, two conditions must be met: Internal transmission fluid pressure must be correct.
What are the conditions for the converter clutch to apply?
For the converter clutch to apply, two conditions must be met: Internal transmission fluid pressure must be correct. The ECM must complete a ground circuit to energize the TCC solenoid that moves a check ball in the fluid line. This allows the converter clutch to apply when hydraulic pressure is correct.
