Outline
• The TCM drives the pressure control solenoid and adjusts the pressure based on the accelerator pedal depression amount, vehicle speed, ATF temperature, and gear shift signal. As a result, line pressure is controlled finely and with high accuracy according to the engine load condition and vehicle driving conditions.
Construction
Operation
• The TCM adjusts the pressure control solenoid pressure applied to the pressure regulator valve by increasing/decreasing the energization current to the pressure control solenoid. As a result, the ATF amount passing through the pressure regulator valve is adjusted and the line pressure is adjusted.
