Shift Solenoid Valve B

DESCRIPTION

Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the park/neutral position switch,
vehicle speed and throttle (accelerator) position sensors. Gears will
then be shifted to the optimum position.

Overrun Clutch Solenoid Valve

DESCRIPTION

The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the park/neutral position switch, over-
drive control switch, vehicle speed and throttle (accelerator) posi-
tion sensors. The overrun clutch operation will then be controlled.
