Hello,

I don't know which oil type use to do my oil replacement.

And I don't know the size tool to remove the drain screw.

Thank you

Most drains are either three eights square drive or a Torx. The first step is to clean around the fill plug and break it free. That will be on the side of the housing. Then the best option is to pull the rear cover, that lets you go in and inspect the gears and bearings and wipe out the case.
