2-3 Accumulator
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
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.
