2014 GMC Yukon XL 1500 Denali 8 Cyl 6.20L


Possible for improved engine/transmission cooling?

First off my Denali has the 6.2 L V8 not a 1.6L thank god. Now to my question. What are my options for improving my engine cooling and transmission cooling. I pull a 26ft travel trailer that is well under my towing capacity but on very hot days my tranny and engine temps still bump up somewhat. If both the engine coolant and transmission fluid/filter have been serviced what are my next options for improvement? Larger transmission cooler? More effective radiator? I really dont know my options. Thanks.
