another newbie question

["Oliver" <sumton@sbcglobal.net>]

I'm looking at the shop manuals, and they show a drain hole in the bottom of
the transmission.  no problem there.  they are showing another bolt hole
paritally up the side, which i am assuming is for refilling?  it seems
awfully low.  and, if you don't mind, neither manual shows anything about
the diffy.

thanks!
