Reverse Clutch Release

Manual Valve 

The manual valve is moved to the Neutral position and blocks drive\reverse regulator (19) fluid feed pressure from entering the reverse (22) fluid circuit. The reverse (22) fluid circuit is opened to an exhaust at the manual valve.

Reverse Clutch 

Reverse (22) fluid exhausts from the reverse clutch thru orifice #44 to the #4 ball check valve allowing the reverse clutch to release.

#4 Ball Check Valve 

Exhausting reverse (22) fluid seats the #4 ball check valve and is forced to pass through orifice #43. Reverse (22) fluid then flows to the manual valve where it exhausts.
