In automatic transmissions/transaxles, the recommended service interval is about every 30,000 miles or 30 months. Nothing prolongs vehicle life more than regular fluid changes. That’s why some auto shops use machines that perform a transmission fluid flush, ensuring that more of this debris is removed before any new transmission fluid is poured into the vehicle. If you're lucky, this debris will settle on the bottom of the pan or housing and not circulate through the system. As the fluid circulates through the parts, it gathers the dirt and metal shavings that can accumulate over time. Vehicles' vital fluids normally perform two important functions: lubricating and cleaning.
