So, I only had the truck for a couple months and didn't have the chance to spend quality time under, around it, like I did my 98 TRD. I am assuming the Towing Package uses a different radiator. Or is the tranny cooler a seperate unit? I don't have the truck here to check. This would be a good one to nail Progressive on, if they are trying to replace my "towing package" radiator with a non-towing variety. Any thoughts out there. Thanks.
