For Subaru 2.5L 31825AA050 TR580 TR690 torque converter locking solenoid valve

The role of the automotive transmission solenoid valve is:
 

        The control mechanical valve completes the oil circuit switching and the pressure regulation of the oil circuit flow, which is controlled by the transmission electronic control module TCU. Transmission refers to the transmission, is used to change the speed and torque from the engine mechanism, can fix or shift change the output shaft and input shaft transmission ratio, which is composed of variable speed transmission mechanism and control mechanism. The types of transmission are: 1, according to the change of transmission ratio can be divided into: stepwise transmission, stepless transmission, comprehensive transmission; 2, according to the control mode can be divided into: forced control type transmission, automatic control type transmission, semi-automatic control type.

When the car started, all the failure lights on the dashboard were on. It was caused by the solenoid valve.

Causes of transmission solenoid valve failure:

The valve body is damaged, the pressure is insufficient, the pressure cylinder clamp is not tight chain, and the pressure cylinder is seriously worn.

Transmission solenoid valve failure solution:

Timely go to the professional regular store to check and add transmission oil, so that the transmission gear is better lubricated, and the automatic transmission oil leakage is seriously short of oil

The oil inlet filter is blocked, the main oil circuit is seriously leaked, the oil pump is damaged, and the connecting rod between the shift lever and the manual valve rocker arm is kept in the neutral or stop gear position.
