How frequently should my transmission’s fluid be changed?
Everett Transmission recommends that our customers change their vehicle’s transmission fluid every 3 years / 36,000 miles. If your vehicle is older, or you use it for hauling heavy loads and/or towing it may be required more frequently. To determine if a fluid change is needed, Everett Transmission recommends an external diagnostic service. An external diagnostic service for a transmission includes checking the level and condition of your transmission fluid, a road test, and putting your car on a lift at our shop to check your external transmission controls.
