When it comes to installing a transmission cooler on your 2007 Dodge Ram Pickup The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient # D13503 will be a good choice for your vehicle. I recommend using just one cooler. I would use just one large cooler.

Using this cooler will prolong the life of your transmission and improve its overall performance, specifically designed for Dodge Ram Pickups with late-model, electronic overdrive transmissions. The cooler has furnace-brazed aluminum construction and 3/4 inch wide turbulator plates that offer more efficient cooling.

The Derale Insta-dapt radiator adapter fits most vehicles with 5/16 inch transmission lines, but not all. In some cases additional fittings or alteration of the OEM lines or hoses may be required for installation. This radiator-style, plate-and-fin heat exchanger provides increased surface area so that the fluids can spread out along the finned chambers to cool faster.

I attached an installation video link below.
