Coast Clutch Applies

Forward clutch fluid seats the #5 ball check valve and passes through orifice #17 into the coast clutch feed circuit. This orifice helps to control coast clutch apply.

Before the first 1-2 shift has occurred, the safety mode valve (34)1 remains in the released position, allowing line fluid pressure to enter the line safety mode fluid circuit.

Line safety mode fluid applies the 4-5 shift valve (374) against 4-5 shift valve spring (373) force. This allows coast clutch feed fluid to enter the coast clutch fluid circuit.

Coast clutch fluid is routed to the coast clutch piston to apply the coast clutch plates.
