I wish I searched this thread before posting mine.
I've not heard the rattle/grinding noise until recently, but it mine makes the same sort of rattle. Only during gear shifts though, not constantly. (of course, there is some trouble accelerating at the same time that's pretty much consistent so I know it's not me...)
