3 speed transmission with odd hole in case

Hey guys, I bought this transmission (with a receipt that it was rebuilt at a machine shop) and once it was filled, we noticed oil on the floor. Tracked it back to coming out of this tiny hole. The hole is below the fill plug level.

Is it supposed to be there?
Can/should/how I plug it?
Will plugging it cause the case to build pressure and blow out elsewhere?

I appreciate any help on this.

So when is this "Old enough to know better" supposed to kick in?
