Shift Solenoid: Description and Operation
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 five 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 each range and also control the strength and weakness of oil pressure to reduce shock when shifting.
