I'm getting a weird sound in mine too. But I think its the exhaust rattling because all the hangers have broken except for its connection to my catalyitic and the final hanger before the muffler. So I don't know, but at the same time, when I accelerate through corners it sort of feels like a fast shaking, or strong grinding coming from under my right foot. I don't think its in the transmission, because it seems fine as far as shifting and whatnot, but I dunno. You know? Blah. I think it might be my car just flexing under shifting weight, but I hope not... ugh, I don't wanna have to touch up the seams or anything. I've been driving it gently since I started noticing that noise, but damnit, I wish it wasn't there. :-/ Oh well.
