#7 Accumulator Check Valve Assembly
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Reverse (22) fluid pressure is routed to the #7 accumulator check valve assembly where it passes into the reverse clutch (23) circuit. Reverse (22) fluid pressure moves the check valve against spring force in order to cushion the apply of the low and reverse clutch.
