The best option for a transmission cooler for your 2015 GMC Sierra 1500 with a 6.2L engine is the 8000 Series from Derale:

- Derale Series 8000 Plate-Fin Transmission Cooler # D13504

The reason I like this cooler the most for your truck is due to how efficient it is; the # D13504 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 over-cool fluids, the rule of thumb with transmission coolers is that size matters so the large 11" wide x 12" tall x 7/8" deep cooler is going to allow for the best cooling efficiency.

Adding the # D13504 is definitely one of the best things you can do for your Sierra because whether you are using your truck for towing or just live in a very warm area, the additional cooling helps prolong the lifespan of your transmission.
