LINE PRESSURE CONTROL SOLENOID OUTLINE [AW6A-EL, AW6AX-EL]

• Line pressure control solenoid is installed on the front valve body. In accordance with the value decided in the
TCM based on throttle opening signal and engine torque, line hydraulic pressure is controlled by linearly
changing the comparable throttle pressure. Through this, it controls operating hydraulic pressure to the clutch
and brakes for smooth shifting. As a fail-safe function, if any line pressure control solenoid abnormality occurs,
the TCM will disable the current to the line pressure control solenoid. (The line pressure is maximized, if the line
pressure control solenoid current is disabled when any abnormality of line pressure control solenoid other than
valve stick occurs.)
