All you need to do is remove the case and then the variator, you will need an impact driver to remove the nut for the variator. The gear you are looking for is right behind it. To cover the hole in the case go to home depot and get a small piece of 1/4 aluminum and cut it to the shape of the hole and then use JB Weld and glue it on. I run a bead all around the outside. It looks good and you can never tell their was a hole. You can also take some sandpaper and sand it to match the texture of your case. Also while you have the variator off check your rollers for flat spots.
