P2722 PRESSURE CONTROL SOLENOID E

Description

INFOID:0000000005250109

• The low brake solenoid valve is controlled by the TCM in response to signals transmitted from the transmis-

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

• The low brake solenoid valve controls the low brake control valve in response to a signal transmitted from

the TCM.
