Well, tooling is cool but you don't need it to make pins like those. Cut the shank off a 5/16" bolt, drill through the center, tap it for a 1/4" bolt. You can install the bolt from the outside of the cover.

I believe the pins are 1/4" in the trans cover and 5/16" on the inside. You'd have to drill the cover to 5/16" to use a roll pin.
