What’s the matter with the automatic transmission not being able to shift gears?

When the automatic transmission of the car cannot shift gears, it means that the oil pressure is abnormal. It is necessary to check the oil pressure of the car engine to see if there is a phenomenon of high or low oil pressure. The failure of the automatic transmission of the car will cause the car to start weakly. block delay.

　　

The transmission is composed of a variable speed transmission mechanism and an operating mechanism. The transmission can be divided into a manual transmission and an automatic transmission. The gearbox can change the rotation ratio of the car, expanding the drive wheel speed and rotation speed. The continuous development of science and technology has changed the transmission from the manual transmission in the past to the current stepless transmission, which makes the fuel consumption of the engine lower when the power is higher. When the rotation direction of the engine is kept unchanged through the gearbox, the car can still run backwards, and the power transmission of the car can be reduced when the car is in neutral, and the engine can start to change gears.
