[R-390] ATF for lube

Hi,

I've used Dexron ATF for lubing the gears and
bushings.  Seems to work fine, stays put, and makes
things turn very smoothly.  BTW I'm told that ATF is
synthetic.  But as far as synthetic goes, it just
means that the molecules are more uniform.  That
uniformity isn't needed for our low rpm geartrains.

Regards,

Bob
