Manual Valve
The manual valve is moved to the drive position and allows line fluid pressure to enter the drive fluid circuit. Drive fluid is then routed to the default override valve.
#2 Ball Check Valve
Drive fluid is directed through orifice #59 into the 45678R CL DR FD fluid circuit which seats the #2 ball check valve against the reverse circuit allowing fluid to enter the 45678R CLUTCH FEED circuit. 45678R CLU FEED fluid is directed through orifice #35 then to the 45678R control valve.
