The best transmission cooler kit for your 2018 Ram 3500 Dually with the 6.7 Cummins Turbo Diesel engine is going to be the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets item # D13611. This plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously. I have linked a review video as well as attached a picture so you can see what this transmission cooler looks like installed.
