Direct Clutch Applies

The 1-2 SS valve is de-energised, blocking feed limit fluid from entering the 1-2 signal fluid circuit and 1-2 signal fluid pressure exhausts through the 1-2 SS valve.

When 1-2 signal fluid pressure exhausts from the 3-4 shift valve (345), the 3-4 shift valve spring (344) moves the valve to the released position. 345 fluid from the 2-3 shift valve flows through the 3-4 shift valve and enters the direct clutch circuit.

Direct clutch fluid is routed to the direct clutch piston to apply the direct clutch plates and obtain Fourth gear.
