Agreed, trans cooler fans would be a good choice.

FYI, there's two different sizes of factory trans coolers:

The smaller of the two came with the lighter duty towing package and has about 4 or 5 rows of cooling fins. Factory light duty towing packages have a flat-4 only trailer connector on the rear bumper.

The heavier duty option has a cooler with 8-10 rows of cooling fins and is matched with the dual 7-pin + flat-4 combo trailer connector on the rear bumper.

The heavy-duty (AKA "Super Cooling") was an option on most trim levels and may have been standard on the higher (Lariat/KR) levles.

Upgrading to the larger cooler, if you have the small one, is a simple bolt-on change and the part is about $100 from Tasca Ford Parts or the like.
