31939-AA191 Automotive transmission control solenoid for Subaru

The transmission solenoid valve plays a key role in the transmission control system, which mainly includes regulating the mechanical valve to realize the oil circuit switching and the pressure adjustment of the oil circuit flow. ‌ These operations are precisely controlled by the transmission electronic control module (TCU) to ensure that the transmission provides the right driving force and shift function according to the road conditions and driving conditions. ‌

As a basic component of automation, solenoid valves are not limited to hydraulic or pneumatic systems, but can also adjust the direction, flow and speed of the medium in industrial control systems to achieve accurate and flexible control with different circuits. In the transmission control system, the solenoid valve drives the actuator by controlling the hydraulic signal to realize the shift and clutch operation. ‌

In addition, the main control parameters of solenoid valve selection include diameter, design nominal pressure, medium allowable temperature range and interface size. Its sealing performance is an important index to evaluate the quality, including the detection of internal leakage and external leakage.
