Honestly, I have both a 6.0 cooler and a Mag-hytec pan-w/a guage stabbed into it. Two gauges for the trans one in the test port and pan. I have no heating issues at all.
Dave, just wanted to get your opinion.

When my money's spent for additional cooling (and then, only if I actually need it) it won't be on a "finned tranny pan".
Added case rigidity? I suppose, but I suspect if Ford had a big problem with cases flexing under "normal" circumstances, they would have cast a more stout case. Saaaay.... There's a business opportunity! Supply a new, more rigid, casting for those making mega-power.

OK, "anything" is an absolute term. All "absolutes" are false, as there's always an exception somewhere. So yes, fins will make a "difference", albeit ALMOST nil. There's a case to be made, too, for touting that deeper pans, without fins, will dissipate more heat due only to the greater surface area. But nobody does, unless they're selling deeper pans without fins.

Thanks for your comments, I am sure someone will appreciate them, but I got better things to do than split hairs on cooling fins...

Not that it matters, but I broke 3 bellhousings out of a GMC 3500hd before I figured out the problem. It was with the 4L80E tranny, and with new motor mounts and tranny mounts, I managed to break 3 of them before I figured it out. Turning on to my road, the road goes up at a sharp angle, and I was always in the turn. It would twist the truck in a bad way. I would hear a popping noise and could never figure it out until on the 3rd tranny. That was an expensive lesson.

So, is case-cracking a problem for 4R100's in SuperDuty's, especially at the power levels most of our members turn out??
Seems we would have heard a little something about it around here over the past few years, and some of our members make considerable power. There are usually other internals that'll snap first, and we know about the fixes for them.
Remember, most of us guys aren't exactly the thousand-horsepower, sled-pulling crowd.
When I start hearing of a lot of problems with cracked or distorted cases, when towing appropriate loads, I'll rethink my position about adding a finned aluminum tranny pan.
Until then, it just seems like bling.
Of course, that's not bad, if you're into that sorta' thing.....
