7A1-14 CONSTRUCTION AND FUNCTION CONTROL VALVE • Employing the direct electronic control (Direct Electronic Shift Control: DESC) for the clutch pressure has simplified the oil pressure circuit, reduced the number of functional components and made the control • The control valve body is divided into the upper body and lower body. All solenoids, oil pressure switch and ATF thermo sensor are installed to the lower body. • Three-way valve type solenoids providing high responsibility are employed. Some of the solenoids are switched between ON and OFF and others repeat ON and OFF at 50Hz (duty cycle system). • When the solenoid is driven based on the signal from the TCM, the oil pressure is changed. The valve is operated by the difference of the oil pressure.
