Reverse Clutch Applies

IMPORTANT: Remember that the function of an orifice is to control the flow rate of fluid and rate of apply or release of a clutch.
#1 Ball Check Valve:

Located in the bottom channel plate, reverse lockout fluid seats the #1 ball check valve and is forced through orifice #13 in the control valve body spacer plate into the reverse clutch fluid passage.

Reverse Clutch:

Reverse clutch fluid enters the reverse clutch housing and acts on the reverse clutch piston to apply the reverse clutch plates.
