"...If you want to install an oil cooler for the transfer case, instead of
drilling holes in the case itself (which could potentially introduce
stress-related problems), why don't you just modify the filler and drain
plugs? "
---------------------snip-------------------------------------------------

Thanks to all who replied--I can't believe I was considering drilling
holes in my transfer case when there are two incredibly obvious holes in it
already. Home Depot probably sells suitable fittings for it as well.

"....automotive electric pumps (that I know
about) are meant for fuel and gear oil is much too thick for them to live
long."
-----------------------snip-----------------------------------------------

As far as the electric oil pump goes, there will be an on/off switch for
the oil pump inside the cab of the truck. You only need to operate it when
the oil is hot, and therefore thinner. Hopefully the consumer-grade oil
pumps sold by JC Whitney will be up to the task.

-----------------------snip------------------------------------------------
"...You might also want to consider using a synthetic gear lube, which
should reduce the operating temperatures somewhat."
-----------------------snip------------------------------------------------

As for synthetic oils, I would tend to avoid it for the time being.
It's not that it isn't suitable (or ideal for that matter). Its just that
my input and output shaft seals leak a little---OK, quite a bit---and
synthetic oil tends to slide past the worn selas with much less effort than
petroleum-based oil.

Again, thanks to all for the great ideas!
