The best transmission cooler for your 2019 Ram 3500 with a 6.7L Diesel Engine is the Derale Series 8000 Transmission Cooler # D13504 because it is the most efficient cooler available for your Ram 3500.

This transmission cooler is a plate-and-fin cooler, which means it uses smaller plates that cover more area than other coolers in order to agitate transmission fluid. Because you cannot overcool fluids, the rule of thumb with transmission coolers is you want the largest one that will fit, which makes the 11" Wide x 12" tall x 7/8" deep Series 8000 your best option.

Adding a transmission cooler such as the Derale Series 8000 # D13504 is one of the best things you can do for your truck if you are towing because no matter what type of engine is in your truck, towing is a stressor and additional cooling keeps temperatures down and helps prolong the lifespan of your transmission.
