You can extend the life of your vehicle's automatic transmission by having a certified transmission technician perform an automatic transmission service regularly. Also, use your vehicle for its intended design purpose. For example, do not tow a boat with a vehicle that was not designed for towing a boat.

Installing an auxiliary transmission cooler in most late model cars and commercial vehicles will contribute to extending the life of your vehicle's automatic transmission.

Check your transmission fluid level and condition regularly to make sure it is full and in good condition.
