J.B. Dlco & Multistate Transmissions recommends changing your vehicle's transmission fluid every 2 years or 30,000 miles. Our technicians recommend you bring your vehicle to our Warren transmission service and repair shop once every two years for a fluid and filter 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, J.B. Dlco & Multistate Transmissions 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 Warren shop to check your external transmission controls and to keep your transmission, and your vehicle, performing properly.
