Reverse 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.

Manual Valve 

The manual valve is moved to the Neutral position, where the valve blocks the line pressure from entering the Reverse fluid circuit. The reverse fluid circuit is opened to an exhaust at the manual valve.

Reverse Clutch 

Reverse fluid exhausts from the reverse clutch and the clutch releases. This action shifts the transmission in to Neutral position.

Boost Valve 

Reverse fluid exhausts from the boost valve and line pressure regulation returns to the normal operating range.

A/T Fluid Pressure Manual Valve Position Switch (TFP Val. Position Sw.) Assembly 

Reverse fluid pressure exhausts from the TFP Val. Position Sw. Assembly. This action signals the PCM that the transmission is either in Neutral (N) or Park (P) position.
