So I have a question. My truck (2005 F-150 with the 4.6L V8 ) didn't come with the factory tow package, and thus the auxiliary Trans-oil cooler. Limiting the towing capacity to 5k. Looking at Fordparts.com to see if I could buy the auxiliary one, the part and picture provided looks like the one already in my truck. It's the smaller radiator looking thing in front of the regular radiator. My question is, was it possible to purchase the truck with just the auxiliary Trans-oils cooler and not the tow package (I'm the second owner BTW), or is there another larger oil cooler that replaces the one already in my truck? I'll post a pic of what I'm talking about later when I get off of work.
