Expert Reply:
Regardless of whether you are towing anything or not you will want the transmission temperature to be between 160 to 200 degrees F. Towing a trailer or carrying more weight in the truck will increase the temperature. Since transmission fluid cannot be over cooled I do recommend adding one to your 2010 Chevy Avalanche. Keeping the temperature as cool as possible will extend the life of the transmission.
You can use cooler # D13504 that you have referenced. To avoid having to cut and flare lines I also recommend the hose fitting # D13035.
I have included a link to our FAQ article on transmission coolers and a link to a video showing a typical installation for you.
