About 2010-2012 Ram 6.7L Cummins Transmission Coolers
The Ram 6.7L Cummins trucks are known for running pretty hot, even at stock power levels and during fairly light towing. Things get even spicier when your tough Ram truck starts churning out more power and torque, tows at the edge of its GVWR or GCWR, or is getting used hard at the track or off-road. Excessive heat isn't great for a complex piece of machinery like a transmission, and keeping things cool is critical for preserving its lifespan and avoiding going into limp mode on your next adventure. Tier One's selection of 6.7L Cummins performance transmission coolers are here to help. These transmission coolers help your Ram dissipate more heat out of your Ram's transmission fluid than the stock transmission cooler alone, which can help your Ram stay out of trouble with heat, even if it's throwing down more power or towing extremely heavy.2010-2012 Ram 6.7L Cummins Drop-In Transmission Coolers
The easiest to install Ram 6.7L Cummins transmission coolers are drop-in transmission coolers like the Mishimoto 2010-2012 Ram 6.7L Cummins Transmission Cooler. Drop-in transmission coolers replace your factory transmission cooler, but generally feature larger surface areas, thicker cores, and more efficient designs that allow them to dissipate far more heat than the factory transmission cooler to keep your Ram's transmission running much cooler.
2010-2012 Ram 6.7L Cummins Auxiliary Transmission Coolers
Auxiliary transmission coolers tend to be universal or semi-universal units that install in conjunction with your Ram's factory transmission cooler or potentially an aftermarket drop-in transmission cooler to provide awesome levels of transmission cooling capability for your tough Ram truck. While auxiliary transmission coolers are harder to install than drop-in transmission coolers, they do provide a ton of cooling potential for your Ram's transmission and are a great choice for professional towing and racing applications. We're pretty big fans of the BD Diesel Complete Xtrude Series Transmission Cooler Kit is a good choice, since it comes with all the lines, brackets, and most of the fittings you'll need to tie the lines into your transmission cooling system.
