What is the TCC solenoid?
What is the 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.
When does the TCC disengage in a manual transmission?
The TCC is very similar to the clutch in a manual transmission. When engaged, it makes a direct physical connection between the engine and transmission. Generally, the TCC will engage at about 50 mph and disengage at about 45 mph. The TCC solenoid is what actually causes the TCC to engage and disengage.
What causes a TCC solenoid to disengage?
Power to the TCC Solenoid is provided through a switch on the brake pedal that interrupts power when the brakes are applied. This is what causes the lock-up to disengage in the test above. When the brakes are applied, the TCC should not be locked up, because power to the solenoid is removed.
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.
How long does it take to fix TH200-4R transmission?
Introduction: First off, don’t let the cut-away view of the TH200-4R transmission above intimidate you. Everything associated with this repair can be done in your driveway and does not involve removing the transmission from the car. It took me about 4 hours to perform, at a leisurely pace, with intermissions for lunch and parts runs.
Where is the TCC solenoid located on a 4L60E?
In essence, the TCC solenoid is like a computer controlled on and off switch for your 4l60e’s torque converter lock up. Where Is The TCC Solenoid Located The 4l60e TCC Solenoid is located on the front passenger side of the transmission near the valve body. The image below shows the locations of various solenoids.
The TCC is very similar to the clutch in a manual transmission. When engaged, it makes a direct physical connection between the engine and transmission. Generally, the TCC will engage at about 50 mph and disengage at about 45 mph. The TCC solenoid is what actually causes the TCC to engage and disengage.
What are the symptoms of a failed TCC solenoid?
The main symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up you will notice the engine’s RPMs staying higher under load at highway speeds. Another symptom of a failed TCC solenoid is a fault code. Common codes associated with a TCC conditions include:
What does the TCC solenoid do on a toque converter?
What Does The TCC Solenoid Do? The main function of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converter’s clutch allowing it to achieve lock up in 4th gear based on a signal from the engine control module (ECM).
