Second Clutch Releases

WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Second Clutch

The Second clutch fluid exhausts from the clutch piston and through the 2-3 drive fluid circuit. This releases the Second clutch, and the transmission operates in First gear.

1-2 Accumulator

Second clutch feed fluid exhausts from the 1-2 accumulator, and the fluid exhausts past the #2 checkball and through the 2-3 drive fluid circuit. The 1-2 accumulator feed fluid fills the 1-2 accumulator as the second clutch fluid exhausts.

1-2/3-4 Accumulator Valve

The accumulator valve regulates the line pressure into the 1-2/3-4 accumulator fluid circuit in order to fill the 1-2 accumulator. Torque signal fluid pressure controls this regulation. Accumulator fluid pressure is regulated to a higher pressure with greater torque signal fluid pressure.

TCC Control Solenoid Valve

Filtered 2-3 drive fluid exhausts from the solenoid and through the 2-3 drive fluid circuit.
