What are the symptoms when the automatic gearbox is broken?

Compared with manual gearbox, automatic gearbox is a transmission device that can automatically shift gears according to vehicle speed and engine speed. AT present, there are four types of automobile automatic transmission, namely hydraulic automatic transmission (AT), mechanical continuously variable automatic transmission (CVT), electromechanical automatic transmission (AMT) and dual clutch automatic transmission. Later, the car editor patiently introduced the symptoms of automatic gearbox failure to friends.

Encounter such a situation may be:

1, automatic transmission has serious oil leakage and serious oil shortage.

2. The oil inlet screen is blocked.

3. The main oil circuit is seriously leaking oil.

The oil pump is damaged.

5. The connecting rod or cable between the gear lever and the rocker arm of the manual valve is lifted, and the manual valve is kept in the empty position or the parking position.

The reasons for the failure may be:

1. Engine idle speed is too high.

3. Improper adjustment of throttle cable or throttle position sensor leads to high oil pressure in the main oil circuit.

4. The main oil pressure regulating valve fails, resulting in high oil pressure in the main oil circuit.

5. The shift actuator slips.

6. The oil pressure solenoid valve does not work.

There is something wrong with this computer.
