The guys around here have grooves cut in the case inboard of the lock pin in both bores at the rear of the case and the one in the front. I have 3 transmissions that are O ringed and they don't leak a drop. I don't know the size of the groove or the o ring but the machinist who does the work would figure that out.
Some people groove the shaft but I don't like that idea.
