Does a Flush Machine Oil Change Require Filter Replacement?

[LenaAnn]

The concept of replacing the filter applies only to engine oil changes. However, engine oil changes do not require the use of a flush machine. Only transmission fluid involves replacement via a flush machine, but transmission fluid does not have a filter at all. Additional information: Here are details on automotive transmission fluid replacement: 1. The replacement interval for automatic transmission fluid is every 2 years or 40,000 kilometers. 2. Due to the highly precise internal structure of automatic transmissions and the high cost of repairs, coupled with the fact that the commonly used gravity drain method cannot fully replace the fluid, it is crucial not to delay automatic transmission fluid changes to avoid greater losses. 3. The transmission fluid replacement points are located on the transmission housing with two bolts: the upper bolt serves as the fill port, and the lower bolt is the drain port.
