Low and Reverse Servo

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Low band fluid pressure is routed to the inner area of the Low and Reverse servo in order to apply the Low and Reverse band. The Low and Reverse band provides engine compression braking when the throttle is released in Manual First - First Gear. 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.
