This 2001-2014 Chevy / GMC 6.6L Duramax Transmission Cooler is now available! Click here to check it out!
Extreme heat is always the enemy, especially when it comes to vehicles equipped with an automatic transmission. The Allison gearbox mated with your 6.6L Duramax is no exception. With the high temperatures produced by an automatic transmission, it seems almost cruel that the sweltering summer heat comes when most of the towing of campers, boats, and other outdoor toys happens. GM did include some help to keep your gears cool. Unfortunately, it’s a little small.
