Upshift Solenoid

1-2 Shift Valve
Controls the speed at which the 1-2 and 2-1 shifts occur.

2-3 Shift Valve
Controls speeds at which 2-3 and 3-2 shifts occur.

Stator Valve
Used only on transmissions having the variable pitch stator, this valve shifts when line oil is exhausted at end of valve when stator control solenoid is energized. This exhausts oil from the variable pitch stator piston and changes from the low to the high angle. When the stator solenoid is not energized, converter oil is directed to the stator piston and low angle is obtained.
