Second Clutch Applies

WARNING: This page is about a different variant/trim than selected.
1-2 Shift Solenoid (SS) Valve

The 1-2 SS valve is energized, allowing feed limit fluid to enter the 1-2 signal fluid circuit. 1-2 signal fluid, together with 1-2 shift control valve spring (367) force, overcomes 2-3 signal fluid pressure and moves the 1-2 shift control valve (366) to the released position. This blocks feed limit fluid from entering the FDL fluid circuit.

1-2 Shift Valve

FDL fluid is exhausted from the 1-2 shift valve (387) and 1-2 shift valve spring (388) force moves the valve to the released position to allow D13 fluid to enter the second clutch and 2345 fluid circuits.

Second Clutch

Second clutch fluid is directed to the second clutch piston to apply the second clutch plates and achieve Second gear.
