Shift Solenoid Valve B
DESCRIPTION
Shift solenoid valves A and B are turned ªONº or ªOFFº 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.

Torque Converter Clutch Solenoid Valve
DESCRIPTION
The torque converter clutch solenoid valve is activated, with the
gear in D

speed and throttle (accelerator) position sensors. Torque converter
clutch piston operation will then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
