Thank you for the photo of your sturdy F-350 that is in need of a little TLC in the form of a transmission cooler to help it when pulling those heavy loads.

For your heavy-duty application you'll want a high-efficiency cooler that will give your transmission the most temperature reduction possible. This means using the largest Class IV cooler that you can fit in the area in front of the radiator and A/C condenser (if present). The cooler I recommend is the Derale # D13105 that you referenced. This large cooler (better than 16 x 12-inches) will take full advantage of air flow into the engine compartment to cool your transmission fluid. You will also need the hose fitting kit # D13025. The linked video shows installation in your exact model truck.

You may also have an option in a pan type cooler. If your transmission model is an E4OD, 4R100, 5R100, or 5R100W you can use Derale pan cooler # D14208. The advantage of pan coolers is that they actually increase your transmission's fluid capacity by over 7 quarts. For the most extreme conditions you could use both coolers at once.
