A transmission cooler is designed to keep fluids at a nominal temperature during periods of heavy use, or high heat. If yours is leaking, replace it now to prevent fluid loss and catastrophic failure.
The transmission oil cooler allows fluid to pass through the core, dropping the temperature of the fluid before it returns to the transmission. This prolongs fluid life and viscosity, as well as providing a cooler fluid to drop transmission temperatures which can be vital to the life of a transmission.
