How Frequently Should My Transmission's Fluid Be Changed?

Arnold's Transmission & Gear recommends that our customers in the greater Denver area change their vehicle's transmission fluid every 3 years / 36,000 miles. The transmission technicians at Arnold's Transmission & Gear recommend bringing your vehicle to our Denver auto repair shop once a year for a transmission fluid change. If your vehicle is older, or you use it for hauling heavy loads and/or towing around the Denver area, it may be required more frequently. To determine if a fluid change is needed, Arnold's Transmission & Gear 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 around Denver, and putting your car on a lift at our shop to check your external transmission controls and to keep your transmission, and your vehicle, performing properly.
