Why an External Transmission Cooling System?

External Transmission Cooling Systems help keep your transmission running at optimal temperatures. Cooler flow is a key factor in keeping temperatures in check and the Lubrication Circuit is responsible for over 90% of transmission cooling. Transmission coolers must not restrict flow to and from the transmission and must extract heat efficiently.

How to Choose:

When choosing a transmission cooler, it is critical to choose a self-regulating cooler. A self-regulating cooler allows the transmission fluid to pass through it under cool operating temperatures so as to allow gear train lubrication while still providing maximum cooling efficiency under hot operating conditions. A thermostatically controlled, fan-forced (reversible rotation), low pressure drop unit is the preferred choice when choosing an optimal transmission cooler for your vehicle. From the bone-chilling cold of Northern Alaska to the radiating heat of the Mohave Desert, this it the premier cooler for any diesel application. Utilizing an ATS Diesel Extra Deep Transmission Pan coupled with an External Transmission Cooling System ensures that you have a fool-proof way of beating the heat!
