I answered your question over in the other post - which you can disregard since you have the 45RFE. Certainly the better of the two trannies installed in the Liberty.
You're in better shape than those running the 42RLE with the standalone trans cooler - your in-rad cooler stabilizes the trans fluid temps much more than the standalone so you don't need an additional cooler. Besides the fact the 45 is a more sturdy unit to begin with. And since you'll be on the highway with air moving over the radiator - and you're adding the HD cooling - you're in great shape.
The biggest issue with towing a trailer - with ANY tow vehicle - is stopping. We can pull a locomotive with our KJ but ain't no way we're gonna stop it. You've CYA with the brake controller you're installing - as long as you drive like you're towing something rather than attempting sports car maneuvers!
