If you overload the vehicle, no amount of cooling will make it haul or tow more than the maximum specified weight. An auxiliary transmission cooler will not increase the towing or hauling capacity of a vehicle. Towing increases the load and puts additional strain on a vehicle’s transmission, thereby increasing the heat that is generated and the cooling levels required to ensure the transmission doesn’t burn out. A Transmission Cooler Is Not a Substitute for Transmission Repair.Ī vehicle used for towing may sometimes benefit from an additional transmission cooler. Once you know what type of cooler you need, we’ll install it and make sure it’s working properly, keeping the transmission cool and running smoothly. AAMCO Colorado can help you make the right decision for your car, based on your driving habits, requirements, and a transmission Vehicle Courtesy Check. Whichever transmission cooler design you choose, rest assured that it will extend the life of your transmission by preventing heat-related failures and improving shifting performance. The small, flat plates allow more fluid to contact the surface inside the cooler, which maximizes heat transfer and minimizes pressure drop. It forces fluid through smaller plates that cause agitation of the fluid. The plate-and-fin style of transmission cooler works on the same principle as the tube-and-fin but is more efficient. The tube-and-fin style of cooler works well but is not the most efficient kind. The heat is carried away by air flowing all around the fins on the outside of the cooler. The heat is absorbed by the aluminum and is transferred to aluminum fins attached to the outside of the tube, which quickly dissipates the heat. It has what is called “turbulators”, which agitate the fluid, which causes it to cool more thoroughly by washing up against the inside walls of the aluminum tube. The tube-and-fin type consists of a tube that carries transmission fluid through the cooling unit.
