hello, i recently purchased my 02 gmc dmax zf6, and i have been noticing a odd noise after shutoff. i do realize most diesels make noise specially when they have higher milage (220,000kms in mine), but this sound is starting to worry me. its kind of a clunking slapping sound, lasts about 2 seconds and it only does it once and a while, but it seems to be getting more frequent. and wondering if anyone has any ideas

Well actualy it made this sound before i did the aftermarket exhaust, but today I found out that it seems to be coming from the tranny. Because if I hold in the clutchwhen I shut it off I never does it
