Transmission oil coolers are engineered to generate the ideal transmission fluid temperature for optimal performance and an extensive transmission lifespan. By effectively keeping transmission fluids at the operating temperature level, they reliably produce the hydraulic pressure need by your transmission to operate while lubricating and cooling essential internal transmission parts to prevent transmission failure and costly repairs. Various applications such as hauling heavy equipment, off-roading, or driving in traffic can bring forth an elevated fluid operating temperature. If the fluid reaches a certain level, it can break down and produce deposits that decrease transmission operation and bring forth internal component failure.

During transmission operation, the transmission fluid efficiently takes in the heat from internal transmission components before dissipating it through the transmission cooler.
