I\'m gonna shoot this thing....... I just got done putting in a rebuilt tranny cuz the old one was vibrating real bad, and making an ugly noise. No sweat, so I get the new one in, and everything seems okay. So I get on the highway today for a few miles, and the same TYPE of thing happens, the transfer case shifter all of a sudden will start to shake violently, then it stops, then it starts. WTF? I know the suspension is shot, but as far as I can tell, no driveshaft weights fell off or anything like that. Could a whipped suspension on a 3/4 ton truck do this? BTW, I'm running a 350/350/203, with a BRAND new converter (TCI).
