Low and Reverse Servo

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.

Reverse fluid is routed to the outer area of the servo in order to increase the servo apply pressure in the Reverse position. The low band fluid is routed to the 3-4 shift valve. The pressure moves the 3-4 shift valve against the 1-2 signal fluid.
