I take a 9/16" paddle bit, place it in the corolla selector shaft hole inside the transmission, and drill from the inside out. This completes the selector shaft hole to the outside of the tranny. It's best to do this with the tranny upside down so that shavings don't fall into the bottom.

I then place the selector shaft in the newly opened 9/16" hole. This nice thing about the mr2's selector shaft is that it has a little dimple at the end. I use this to center a 1" paddle bit to drill the oil seal hole.

So, with the tip of the bit in the dimple, I bring the drill down onto the transmission perfectly centered. Now, 1" is slightly too small for the seal, so I then take my dremel and widen the hole slightly until the seal can be tapped in with a hammer.

Pretty easy.
