As a footnote: I was curious (could not recall) if the integrated transmission cooler was part of the GM towing package or not. They don't list it as a component on the website so I have to conclude that it's standard on any truck. I was unhappy to learn when I picked up a Traverse that the trans. cooler is part of the tow package option. Adding the hitch as an accessory leaves you with a limited tow capacity for that reason, so it's only good for a bike or cargo rack.
