Shift Solenoid: Description and Operation
SOLENOID VALVE
DESCRIPTION
TCM calculates the best condition using the information from all kinds of sensors. If the solenoid valve receives the information on the oil pressure,
the solenoid valve actuates according to the driving signal. All kinds of regulators in the valve body are controlled to change the oil passage and also
the line pressure is controlled by TCM.
PWM (Pulse Width Modulation) SOLENOID VALVE
Structure and functions
PWM solenoid valve is composed of six solenoid valves and the oil capacity in the solenoid valve is changed by the electric duty value of TCM. The
oil pressure of the valve body and the torque converter engages or disengages the damper clutch. The solenoid valves send the operating oil pressure
to the clutches and brakes at the each range and also control the strength and weakness of oil pressure to reduce the shock when shifting the range.
