When you want to move up and down, there will be a sense of impact, and there will be an obvious setback when changing gear. There will be a strong feeling of frustration when entering gear, and the movement of entering gear is not smooth. When the car is driving, the gearbox will emit abnormal noises.

The failure of the solenoid valve of the automatic transmission is generally manifested as that when the car starts, when the gear selection handle is suspended from p or n to d gear, the vibration of the car becomes larger, and the upshift of the automatic transmission of the car instantly produces violent vibration during the driving process.

The failure of the magnetic valve will lead to many problems, such as transmission shift stop, slip, gear impact, inability to upshift and so on.

The gearbox won't downshift. If the transmission does not downshift, one of the shift solenoid valves may be stuck in the open/closed position, which will prevent oil from entering the transmission body to pressurize the correct gear.

Automatic transmission solenoid valve is broken the following phenomenon: solenoid valve coil short circuit or break: Detection method: First use a multimeter to measure its on and off, the resistance value is close to zero or infinity, it indicates that the coil short circuit or break.

There may be problems with the metal lead of the socket and the cable connection of the plug. It is best to develop the habit of inserting the plug into the socket after screwing in the fastening screw, and the coil behind the valve stem screwing in the fastening nut. If the solenoid valve coil plug has a light emitting diode power indicator, it must be connected immediately when using DC power to drive the solenoid valve.
