1 Reverse & 6-7-8-9 Clutch Applies

1 Reverse & 6-7-8-9 Solenoid F 

The 1 reverse & 6-7-8-9 solenoid F de-energizes releasing pressure against the 1 reverse & 6-7-8-9 regulator valve spring force. This allows LINE fluid to enter the 1 REV / 6789 FEED fluid circuit. 1 REV / 6789 FEED fluid is routed thru orifice # 40 to the latch valve and to the clutch selector valve.

Latch Valve 

1 REV / 6789 FEED fluid is directed into the latch valve applying pressure against the latch valve spring force. This blocks DRIVE 2 fluid from entering 1 REV / 6789 LATCH fluid circuit.

Clutch Selector Valve 

1 REV / 6789 FEED fluid is routed thru the clutch selector valve into the 6789 CLUTCH fluid circuit. 6789 CLUTCH fluid is directed thru orifice #42 and to ball check valve #5 and the 6789 clutch assembly.

#5 Ball Check Valve 

6789 clutch fluid seats the #5 ball check valve against the 1 REV / 6789 LATCH fluid circuit allowing 1 REV / 6789 FD fluid to enter the LATCH fluid circuit. LATCH fluid is directed to the clutch selector valve applying pressure with the clutch selector valve spring force.

6-7-8-9 Clutch Assembly 

6789 CLUTCH fluid is forced thru orifice #36 to the 6-7-8-9 clutch assembly. 6789 CLUTCH fluid is directed into the 6-7-8-9 clutch piston spring force which applies holding force to the 6-7-8-9 clutch plates.
