Is it necessary to replace the filter when changing AT transmission fluid?

[SabrinaRose]

Replacing AT transmission fluid does not require changing the filter. The relevant information about transmission fluid is as follows: Transmission fluid replacement interval: Among car maintenance items, transmission fluid replacement is also a very important one. Generally, transmission fluid needs to be replaced every two years or after driving approximately 40,000-60,000 kilometers. However, there is a filter inside the transmission fluid tank, and often when changing the transmission fluid, the transmission fluid filter element is not replaced. Function of transmission fluid: During the use of a car, friction occurs between the mechanical metal components inside the transmission, generating some impurities and metal debris. The function of the transmission fluid filter element is to filter out iron filings, sediment, and other impurities from the transmission fluid, supplying clean transmission fluid to various components, thereby providing lubrication and cleaning effects.
