Direct 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.

Direct Clutch 

The direct clutch fluid exhausts and the direct clutch releases.

#6 Checkball (Direct Clutch Release) 

Exhausting direct clutch fluid seats the #6 checkball. This fluid is forced through the #25 orifice in order to help to control the direct clutch release.

2-3 Accumulator 

Direct clutch feed fluid exhausts from the 2-3 accumulator, unseats the #5 checkball, and exhausts past the 2-3 shift valve. The 2-3 accumulator feed fluid fills the 2-3 accumulator as the direct clutch feed fluid exhausts.
