I haven't replaced the ATF pan in my F150, but I did do so in my 1970 Dodge Charger (440 Six Pack) and noticed a large drop in TFT. There were 2 reasons for this that I can think of:
-More capacity= more surface area of the pan= more heat dissipation
-Switching from a Steel to an Aluminum pan changed the heat transfer rate with the external air
But, I still agree that buying a nice ATF cooler that's similar to a V10 SD and bolting on a couple 6" fans for low speed towing is going to beat a deeper pan any day.
