I don't know about pulling the speedo drive from the transmission to fill it with oil. I have never heard of that....
Should be a square plug on passenger side of main case. Take this plug out, and fill to the bottom of the hole.
If you have a posi-trac, be sure that you use the right oil if you have to put some in....
