examine the hole carefully. does it look like it was made as part of the design or does it look more like damage of some kind? if it looks like its supposed to be there, is it threaded? if so, then it may be that a plug was there and worked its way out. sounds much like on rear differentials, where the plug hole is located near the top, and you fill with fluid until it starts running out the hole, the replace the plug.
if it is NOT threaded, then the only thing I can of is that it is similar to the weep hole on water pumps (which is a place where they will start leaking right before the pump fails - sort of a warning device).
