Does the transmission fluid need to be changed regularly? What happens if you never change it?

When buying a car, we have been emphasizing the importance of the three major components, but after buying back the car, some car owners tend to ignore the importance of the transmission. Let's take the automatic transmission as an example, the automatic transmission itself is a more complex mechanical structure, there are countless clutch plates and brakes need to be cooled, it not only has to withstand the impact of shifting gears, but also needs to withstand high torque.

Some car owners react to the transmission will often be stuttering, shift is not smooth, dragging gears and so on, these in addition to its own mechanical institutions, mechanical matching, in fact, transmission fluid is also a key element. It's no exaggeration to say that of all the fluids in a car, transmission fluid has the highest requirements and can be understood as one of the most expensive. So, it is necessary to change the transmission fluid regularly, so what happens if you never change the transmission fluid?

It is mentioned above that the clutch plate in the transmission is driven by the transmission oil, the transmission oil will also take away some worn metal debris, if you do not change the oil for a long time, these metal debris is more and more, imagine how it will be if it is the engine oil? Cylinder pulling! In fact, the transmission a reason, although it will not be as bad as the engine, but it will affect the performance of the transmission itself.

For example, after the transmission oil is dirty, it will block the oil circuit, resulting in the transmission valve body work abnormally, so in the past, heavier rattling, shift delay, can not hang up the gears and so on came. Imagine what it would be like to drive in the middle of the road and suddenly not be able to hang up the gears....... What kind of mood is it to be in a hurry and suddenly not be able to hang up the gears?......

This is also why we should regularly replace the reason for the transmission fluid, previously encountered a lot of similar failures, when the owner realizes that after the change of transmission fluid, it is already too late to diagnose the results have been biased in favor of other parts of the body, such as transmission valve body, that spend more money than the oil change.

How much time to change the transmission fluid?

Generally speaking, the replacement cycle of the transmission fluid for 50,000-60,000 kilometers to replace once, specific should refer to the vehicle manual above the specific requirements. The sales mouth of the life-long maintenance-free transmission fluid can not be completely believe, because the mechanical components in the operation process will have wear and tear, and different use of the environment also need different treatment, so there is no "life-long maintenance-free" said!
