Transmission Cooler : A transmission cooler is designed to radiate heat from the transmission and is cooled by air or coolant. It usually consists of a radiator like core that contains many small tubes and brass or aluminum fins to help radiate the heat. The transmission pump creates transmission pressure and this circulates the transmission fluid through the transmission cooler.
A air cooled transmission cooler will resemble a mini radiator in appearance. These transmission coolers rely on the air moving rapidly through the fins or the transmission cooler to reduce the heat of the transmission.
A water cooled transmission cooler may be found inside a radiator or on the transmission. Engine coolant flows through the fins to regulate the transmission temperature. If the water cooled transmission cooler is located inside the radiator, the radiator must be replaced to replace the transmission cooler.
A transmission cooler should be flushed or replaced whenever a transmission has been replaced or rebuilt. Metal and other fragments of transmission parts can lodge themselves within the small coils inside the transmission cooler. If not flushed or replaced, the transmission cooler may be stopped up which reduced the cooling capacity if the transmission cooler or the fragments may go back into the transmission causing more problems with the transmission.
Transmission coolers can go bad in other ways that can be catastrophic to the transmission. Coolant leaks within the transmission cooler may cause coolant to get inside the transmission which ruins the clutches inside the transmission. Other times the transmission fluid may get into the engine coolant causing cooling system problems as well. Air cooled transmission coolers can develop external leaks which will ultimately cause a transmission to loose transmission fluid.
