I accidentally jacked up my honda pilot by the trans cover and I think I may
 

have damaged something.? I didnt know where to jack up the honda pilot so I used a cover which covers the transmission and it bent into the trans. After this I heard like a purrr whenever I turned or sometimes when I gave it gas. It is a quite purrr but it worries me. The part of the trans that atually made contact with the cover is the part were a universal connects to a long shaft that turns when you you drive. I wonder if I bent anything or smashed something. Could this be what is causing this noise? Any ideas would be helpful.
