I monitor transmission temps when toeing and will tell you that in 5 or 6 while towing, the temps go up. I usually lock out 5 and 6 and tow in 4th at all times since it's as close to a 1 to 1 ratio as possible. Hills need 3rd or even 2nd if it's a 7 percent grade.

Wow, that surprises me. We tow a 5,500 pound RV trailer with our 2012 F150. It pulls in 6th gear 97% (or so ) of the time. Rarely does it need 4th gear; takes quite a significant climb; and I've never seen 3rd or 2nd. 3.73s; 62 mph; 1,700 RPM 6th gear.
Our transmission temperature stays right at 195 regardless of the gear we are in. Might see 200 degrees on a long, hard climb on a hot day. We must have the same transmission. Do you have trailer tow or max tow package with a transmission cooler?
