ATS 01-05 6.6L Duramax External Transmission Cooling System

External Transmission Cooling Systems will help to keep your transmission running at optimal temperatures. Cooler flow is a key factor in keeping temperatures in check. The Lubrication Circuit is responsible for over 90% of transmission cooling. Transmission coolers must not restrict flow from and to the transmission, and must extract heat efficiently. When choosing a transmission cooler, it is critical to choose the one that is a self-regulating style 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 extremely hot operating conditions as well. 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 is the premier transmission 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.
