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.
