Dude, I was in your shoes yesterday...except I got the drain plug out but could not get the fill plug out. The glory of a steel plug in an housing.

What a guy that was helping me ended up doing it taking a center punch to the outer edge and pounding it until the impact created enough torque to get it moving. Of course, I already have a new plug on order and did not tighten either very tight.
