Automatic transmission, also known as automatic transmission, Taiwan is called self-propelled transmission, Hong Kong is called automatic wave. Usually, it is a kind of automobile transmission that can automatically change the gear ratio in the course of driving, so that drivers do not have to shift gears manually. It is also used in large equipment railway locomotives.
Many automobile enthusiasts like to learn some knowledge about automobile maintenance and repair by themselves. They solve a minor problem by themselves. They can change tires, oil and filter everything, but they don't necessarily know enough about some new things. For example, now more and more popular automatic transmission, in the replacement of its transmission fluid can not be used in the original simple method.
In the eyes of most drivers, changing the transmission fluid (atf fluid) in the automatic transmission is the same as changing the engine oil. As long as you find a place to put the old oil, tighten the plug, pour the new oil into it and check the fuel ruler, you will be all right.
Modern automotive automatic transmission is a highly precise power transmission device, which is controlled by computer. It is equipped with many precise components: hydraulic torque converter, solar wheel, planetary wheel and complex and small oil passage. They are very sensitive to pollutants and temperature changes. If the necessary maintenance is lacking, the automatic transmission will have some malfunctions, such as rough work, difficult shifting and so on. According to statistics, 90% of the automatic transmission failures are caused by the deterioration of transmission fluid pollution.
Traditional regular discharge and filling of transmission fluids will leave more than 75% of the old transmission fluids in the cooling pipes of hydraulic torque converters and transmission. When new transmission fluids are added, they will be immediately polluted by the old transmission fluids in the system, and the unexploded sediments will seriously affect the performance of the system.
