I need to upgrade my tranny cooler for my tow vehicle. While it was warm last week but not "August in the south hot", my tranny temps reached 200 while towing to CMP last week. That seems a little high for me.

How about your opinions on suppliers, experiences, etc. FWIW, I am towing a 24' enclosed with a 2500 Chevy Crew diesel with Allison Tranny.

I am looking at a Setrab cooler that shoudl be plug and play. A "diesel specialist supplier" retails these for $450 but I have found them for ~ $250 or less.

Ideas?
