Quick Ship SKU #: DD-67L-1116-TCOOL Driven Diesel Transmission Cooler Kit 11-16 Ford 6.7L Powerstroke

Have you ever watched the transmission temperatures start to rise and begin wondering whether you need to let the truck cool down to avoid burning up your expensive transmission? If so, you're not alone. Avoid this by upgrading your truck with this transmission cooler kit which adds an inline liquid to air heat exchanger for rapid heat reduction.

This cooler was tested for thousands of miles in the Arizona heat, both heavily loaded and unloaded, driving at highway speeds and in stop-and-go traffic. Long gone are the 210°F+ (unloaded) and 240°F+ (loaded) temps. Hammering on the truck while pulling an 18,000#, 48' triple axle race trailer across the Arizona desert in August, the highest temperature seen on the test vehicle was 220°F...and the temperature dropped noticeably as soon as the abuse let up! Simply put, the temperature drops are fantastic!

This kit retains the OEM cooler, adding this liquid to air heat exchanger after the liquid to liquid unit. The cooler adds approximately 1-1.5 quarts of fluid capacity to the system. Installation will take the average DIYer 3-6 hours, depending on experience.

IMPORTANT NOTE: Unless already modified, 2011-2016 trucks have a thermal bypass valve in the transmission cooler passage in the valve body. This valve controls fluid flow to the cooler(s). With an unmodified valve body and the Driven Diesel cooler, you may not see temperatures significantly below 200°F, as the valve will bypass the cooler if the fluid temperature drops too much. Using the Driven Diesel cooler with the factory thermal bypass valve in place should still result in a very noticable temperature drop, and overall transmission temperatures hovering right around the openeing temperature of the bypass valve. If you have a modified valve body or aftermarket transmission, and your builder has either modified or eliminated the thermal bypass valve, you will likely seeeven lower temps.
