Rob,
I started to respond to the first of your posts, but then had the good
sense to look ahead and see if John L. or someone hadn't already posted a
response. John had and it was, of course, a good one. I usually try to find
some little thing in John's posts to quibble about, but in this case
couldn't find even one.
My son, who is something of a 727 expert, says that running low on fluid is
the single most destructive thing you can do to an auto tranny. In your
case, you can't, at this point, do anything about whatever happened, but it
still sounds like information you should have for future reference. Your
external cooler, as John said, is a good thing. If you put that screen or
whatever in, put it out at the inside of the grill, not against the fins of
the cooler, or the condenser or the radiator.
Daniel, I suspect getting the fluid up to operating temperature as an
important factor, varies as to where you live. Not much of a problem here
in California, but in Montana this time of year, I suspect the fluid looks
and feels and circulates more like butter on cold mornings. You're forgiven
for the triple post, and that from one who frequently apologizes for
screwing up posts by not putting in the subject or whatever.

A thought about 727 trannies in general. I made a post a year or more ago
about fluid leaking out of where the shifting shaft goes into the case and
said that the labor was extensive, but the seal was a hardware store
o-ring. Other peoples responses about dealing with this problem  sounded
like they were talking about something entirely different. Last weekend, we
changed the seal on my 79 Terra, and it was an external seal entirely
different than the one I had done before, and fit the descriptions
previously posted exactly. Unlike somebody described at the time, I had to
drop the valve body and put in the new seal rather than being able to do
the whole job from outside the tranny case, but maybe that was just me.
