[AT] Gear case oil: If a little is good, a lot is better?

[Dean Vinson]

Time to pull the PTO housing off my 1950 M Farmall and see if I can figure
out why the engagement lever won't move.  Operator's manual says the
capacity of the transmission and differential case is 13 gallons.  I just
drained 18 out of there... had to scramble around to find something to put
it all in.  I can see there being a little more than the book number, but
five gallons more??
