i might be able to tell u what it is i had the same problem till i pulled it out and i had a broken piece of presure plate casting that was rattling around probably my driving the shit out of her not only that the pressure plate almost seperated from the other piece where the clutch grabs. then . I still drove around and i found pieces of casting from tranny case in there as well and a pice of the starter casing . I know I know I couldn't belive what i was seeing coming out of there . My gears are fu**ed anyways i'm getting a rebuild or a jdm tranny .
