Gee, I guess I finally have to post for the record that I WAS KIDDING.
It was funnier while people were still in suspense, but there you have it.
It was just an off-handed smart-aleck remark that made me laugh inside, and I had to post it.

Since the engine is turning the opposite direction, I'd also assume that the coolant flow is not optimized, allowing the heads to get too hot.
Laugh, but I did have a in-line 6 cyclinder Mercury outboard that ran backwards in reverse. It had two sets on contacts in the throttle and a push button start. When you pulled the throttle to reverse the engine would stop. Push the start button and the distributer rotated 180 degrees and the engine ran backwards.

Herb,
I suppose if you were setting a land speed record for backing a trailer, you might have issues with the wind blowing the opposite direction from the fan...
What I really think is happening is that the torque converter is slipping constantly at low speeds and high torque, which can generate a ton of heat and produce extreme transmission fluid temps.
If you are in 4x4 anyway, try sticking it in low range, and I bet the problem goes away.
I would imagine the ATF could have hit temps that could break it (the oil) down if it got hot enough to drive the engine temp gauge up that high, so an early filter change/ fluid flush on the transmission might be a worth while investment...

Herb, the engine is overheating when you back up because the fan is trying to push air out the front of the truck.
Since the engine is turning the opposite direction, I'd also assume that the coolant flow is not optimized, allowing the heads to get too hot.
Maybe they can come up with a way to keep the engine spinning the same direction all the time someday?

Hohn, I wonder how many people went outside to have their wives hold the brakes with the tranny in reverse, pop the hood up and try to figure out if the engine is turning backwards.
That was a good one! Knowing you though from your other posts I don;t usually take them seriously even when you are serious

I'm surprised no one mentioned the Ram Air effect of the hot exhaust gasses re-entering the system. I am positive that that would have a detrimental effect on the thermal dissipation properties of the transmission.
