2 liters of automatic transmission fluid is added, what will happen if the automatic transmission fluid is added too much

The amount of the automatic transmission oil depends on the model and the replacement method. If the oil is changed by gravity, about 4 liters of oil is required, and about 9-12 liters of oil is required to change the oil with a circulating machine. But what happens if the automatic transmission fluid is added 2 liters more?

What happens if the automatic transmission fluid is added?

1. If the automatic gearbox oil is added too much, more air will enter the gearbox, causing air blockage in the oil drain hole on the control valve, resulting in poor oil drain and shift shock;

2. If the automatic gearbox oil is added too much, the liquid level will be too high. During the driving process of the car, it is easy to contact the rotating parts. When the rotating parts stir the oil, bubbles will appear. After the oil with bubbles enters the oil pump, it will cause oil pressure. unusual;

3. If the automatic gearbox oil is added too much, the resistance of the gear rotation will increase, which will affect the transmission efficiency of the gearbox and reduce the heat dissipation function.

The automatic transmission oil needs to be filled in an appropriate amount, and it cannot be added too much or less. You can check the liquid level through the transmission oil dipstick, and the liquid level is just above the middle. Moreover, it is necessary to replace the special oil for automatic transmission specified by the manufacturer. This is because the internal structure, friction components and sealing components of different automatic transmissions will be different. The original oil is specially formulated according to the structure and material of the transmission. , No matter how good the quality of other types of oil is, it may not be suitable.
