Shift Solenoids "A" & "B"

Transmission is shifted up or down by 2 electric solenoids. Both solenoids are located on valve body. See Figure. Ignition power is supplied to each solenoid by the transmission fuse. Solenoid "A" controls hydraulic pressure to 1-2 and 3-4 shift valves (if equipped). Solenoid "B" controls hydraulic pressure to 2-3 shift valve.
