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 D432 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.
