P2713 PRESSURE CONTROL SOLENOID D

Description

INFOID:0000000005250303

• The high and low reverse clutch solenoid valve is controlled by the TCM in response to signals transmitted

from the transmission range switch, output speed sensor and accelerator pedal position sensor. Gears will
then be shifted to the optimum position.

• The high and low reverse clutch solenoid valve controls the high and low reverse clutch control valve in

response to a signal transmitted from the TCM.
