1-2-3-4-6-7-8-10 Reverse Clutch Applied

1-2-3-4-6-7-8-10 Reverse Clutch Regulator Valve 

Shift solenoid valve D is energized and applying low pressure against the 1-2-3-4-6-7-8-10 reverse clutch regulator valve allowing LINE (2) fluid to enter the 1234678-10R CLUTCH (30) fluid circuit. 1234678-10R CLUTCH (30) fluid is also directed through orifice #21 into the 1234678-10R CLUTCH FEEDBACK (31) fluid passage to the 1-2-3-4-6-7-8-10 reverse clutch regulator valve.

1-2-3-4-6-7-8-10 Reverse Clutch Assembly 

1234678-10R CLUTCH (3o) fluid is directed through orifice # 24 into the 1-2-3-4-6-7-8-10 reverse clutch assembly but not with line pressure. It only has enough pressure to prevent the 1-2-3-4-6-7-8-10 Reverse Clutch from slip.
