i have a 93 4.0 v6 xlt super cab and at start up with or without clutch engaged there's an awful rattle that sounds like its coming from the trans. it goes away after a few minutes at idle, but comes back with acceleration or going up a hill.

everything shifts nice and the clutch feels fine. to me it sounds like a heat shield or something rattling but everything seems tight...i tried to let it rattle while running by myself and went to run under real quick and it stopped....can't stand the noise. anyone had this issue with this model?
