Keeping your automatic transmission fluid at its optimum temperature, whether you're racing, towing, or off-roading, is an often overlooked area of performance and reliability. Protect your investment with a Be Cool external automatic transmission cooler module. This insurance policy for your transmission includes an aluminum, dual pass cooler and an electric fan (puller or pusher) with aluminum mounting brackets. A remote electric fan gives you many options on where to mount the fan on your vehicle with no need to block the radiator anymore. That's just cool.
