What happens when you put the TCC on a car?
What happens when you put the TCC on a car?
While the vehicle is slowing and approaching a stop, the TCC’s application is undesirable. Like the clutch on a manual transmission, it causes the vehicle to stall. The clutch plate contains a spring and hydraulically controlled pistons.
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.
When does the TCM disengage the torque converter?
The TCM delays the engagement of the TCC until the engine reaches a preset temperature. The MAF sensor monitors the volume of air passing through the air tube. The TCM disengages the TCC while the engine is accelerating. Most transmissions disengage the TCC during deceleration to prevent high emissions.
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.

When does the converter disengage in a car?
This allows the converter clutch to apply when hydraulic pressure is correct. 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.
