2 - 3 - 4 - 6 - 8 Clutch Applies
CB26 Pressure Control Solenoid 4
The 2-3-4-6-8 control solenoid energizes allowing line fluid to enter the S4 VFS SIG fluid circuit which applies pressure against the S4 vfs accumulator spring-force and against the 23468 control valve spring force. This allows 13567 CL/23468 CL FD fluid to enter the 23468 CLU fluid circuit. 13567 CL/23468 CL FD fluid also passes thru the 23468 control valve orifice #39 into FDBK. 23468 CLUTCH fluid is directed to the #10 ball check valve and thru orifice #44 to the 23468 clutch assembly housing.
#10 Ball Check Valve
The 23468 CLU fluid seats the #10 ball check valve against the 45678R CLU fluid circuit. 23468 CLU fluid is also directed to the #1 ball check valve.
#1 Ball Check Valve
23468 CLU fluid seats the #1 ball check valve against the REV fluid circuit. This allows 23468 CLU fluid to enter the 23468 C/REV fluid circuit which is directed to the default override valve.
#3 Ball Check Valve
Default Latch fluid seats the #3 ball check valve against the S8 ON/OFF SIG fluid circuit. Allowing DEFAULT LATCH fluid to enter the DFLT LATCH/S8 ON/OFF SIG fluid circuit. DFLT LATCH/S8 ON/OFF SIG fluid passes thru orifice #23 to enter the default override valve applying pressure against the default override valve spring force. This allows DRIVE fluid to enter the 45678R CL DR FD circuit which seats the #2 ball check valve against the REV circuit.
2 - 3 - 4 - 6 - 8 Clutch Assembly
The 23468 CLU fluid passes thru orifice #44 continuing to the 2-3-4-6-8 clutch assembly housing. 23468 CLUTCH fluid applies pressure against the 23468 clutch piston which applies holding pressure to the 2-3-4-6-8 clutch plates.
