The engine oil is a much better gear lubricant, the reason that it n= ormally runs in ATF is for the clutch & brake operation in an automat= ic transmission, heavier oil would limped engagement & disengagement.=

Tracy,
 
   Ian brough up a point that could also apply to the
re-drive.  Since the planet ass'y was originally designed<= /DIV>
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 mat= ter,
but I thought I'd ask.
 
Dale
(to whom the thought just occurred that this may have already
been discussed - some years ago - and could be in the
archives.)
