If you have to rebuild the tranny, it's not because of towing heavy. It's because of ignoring the tranny sump temp and allowing it to exceed 225. The stock tranny temp gauge on SuperDuty pickups is inadequate because it's an idiot gauge that doesn't show the actual temp. Green means go, but yellow means stop and red means you probably need to replace the tranny and torque convertor. On a Ford, you need to add an aftermarket tranny temp gauge that shows sump temp, then drive by that gauge and never allow more than 225. Heat, not hard work, is the tranny killer.

Actually the extra power when towing at or near max overloads the clutch pack. slippage occurs.

That's the dry hitch weight. Nobody tows a dry trailer. For that size trailer figure at least 17% hitch weight. Trailer GVWR is 15,500 so wet and loaded gross trailer weight will be at least 14,000 pounds, and minimum hitch weight will be will be around 2,380. Load the trailer full of toys and the gross will be around 15k with 2,550 hitch weight.

7060 truck weight
2380 hitch weight
----------
9,440 = overloaded by 240 pounds without a trailer full of toys.
==========
7060 truck weight
2,550 hitch weight
--------------------
9,610 = overloaded over the GVWR by 410 pounds with a trailer full of toys.
==========

7060 truck weight
15,000 gross trailer weight
----------
22,060 GCW
18,500 GCWR
--------
3,560 pounds overloaded over the GCWR of the truck
===========

As I explained in my previous post, your SRW is going to be overloaded with any trailer that grosses more than about 12,000 pounds. You need a newer dually with 23,000 or more GCWR to tow that 5er without being overloaded.
