The performance of automatic transmission oil shortage, how to change automatic transmission oil

Automobile gearboxes are divided into automatic gearboxes and manual gearboxes. Many cars now use automatic gearboxes. The operation of automatic gearboxes is simpler and more convenient to drive. Transmission fluid is the key fluid of the gearbox. Automatic gearboxes need to use special automatic transmission fluid. However, transmission fluid is a consumable and will change over time.

Transmission oil can play the role of cleaning, lubricating and sealing the transmission. It also has a certain heat dissipation function, and it can also provide hydraulic pressure. It can be described as versatile and powerful. After using the car for a long time, some sealing rings will inevitably age and crack, causing oil leakage. The lack of oil in the automatic transmission may be caused by the transmission oil leakage or natural wear. What is the performance of the automatic transmission lack of oil? ?

Automatic transmission oil shortage symptoms

1. The car is jittery, and the gear shift is frustrating and not smooth;

2. Abnormal noise in the gearbox;

3. The car speeds up slowly, the acceleration is weak, and the fuel consumption increases;

The occurrence of the above situation means that the automatic transmission oil is insufficient and needs to be supplemented or replaced in time. IfFindThe color of the automatic transmission oil has become darker and thicker. It is recommended to replace it in time. How to change the automatic transmission oil?

Due to the complicated structure of the automatic transmission and the high precision of internal parts, the requirements on the transmission oil are also higher. Special automatic transmission oil is required, and the quality of the automatic transmission oil is required to be good. Therefore, when replacing it, Drain the old oil cleanly, generally use a circulating machine to change the oil, the oil change rate is high, and the old oil of the original car can basically be drained. The cycle machine uses pressure to push out the old oil with new oil, so that the new and old mixed oil can be extracted while adding new oil. The disadvantage of this method is that it consumes more fuel, and the replacement cost is more expensive and the cost is higher, but the effect is obvious. Suitable for automatic gearboxes.
