I'd put in a bigger cooler, personally. The transmission you have (assuming it's a 1/2 ton) is the 4L60E and while it's not awful, it's also not really great for towing. You could put a 2nd cooler in place (i.e. 2 of the same) or one big cooler, the enemy of any automatic transmission is heat. I ran this cooler: https://www.amazon.com/Hayden-Automotive-679-Rapid-Cool-Transmission/dp/B000C3BBKS on my Yukon XL, which has the same drivetrain you do - never had any transmission issues.
Now, the bigger question is whether or not an Avalanche is really adequate for your needs. Is it a 1/2 or 3/4 ton Avalanche, and how big is the trailer (length & loaded weight)?
