Have a 2007 Suburban 170k miles and I'm towing a 29ft Travel trailer. My tranny has been hitting 230*. I'm wondering if upgrading to a deeper fined pan https://www.yourcovers.com/transpan_9427.php and changing the fluid and filter would help get the temps down. Also I don't think I have a tranny cooler. Im hopping that the truck can last 2 more years and I can upgrade to a New 2017+ 3500HD Denali dually.
