ok, theres something under my car that vibrated really bad and its worryin the u kno what outta me. Its coming from the mid front, probally the trans area, but it only happens between 2300 and 2500 rpm's then goes away...any ideas?

can you make the sound sitting still by reving to the rpm range or is just under load you hear the sound?
