Tracy,

   Ian brough up a point that could also apply to the
re-drive.  Since the planet ass'y was originally designed
for lubrication with ATF, is there any particular reason
why it couldn't be run as a closed system with a "scavage"
pump circulating ATF, instead of using engine oil?

   Dunno if there's any advantage to the ATF, for that matter,
but I thought I'd ask.

(to whom the thought just occurred that this may have already
been discussed - some years ago - and could be in the
archives.)
