The noise is definatly more than "average".
Fluid and filter was changed about 1 year / 2,000 miles ago. Perhaps I screwed that up when I did it then? Not sure how I could screw it up. Pretty easy to pull pan on this car, so I may do it just for a check.
Where is the Governor located? is it inside the pan area (something to do when pan is off), or on the exterior case?
