Walker Transmission recommends changing your vehicle's transmission fluid every 3years/36,000 miles. Our technicians recommend you bring your vehicle to our Wheat Ridge ~ Denver transmission service and repair shop once a year for a fluid change. 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, Walker Transmission recommends an external diagnostic service. This includes checking the level and condition of your transmission fluid, a road test, and putting your car on a lift at our Wheat Ridge ~ Denver shop to check your external transmission controls and to keep your transmission, and your vehicle, performing properly.
