I have a 93 xlt auto. Just bought it last week. This is difficult to explain but ill give it a shot. As I am driving along, the gear in which the truck is in doesn't seem to matter, it will suddenly start vibrating and humming loud. It seems to happen when it is nearing a shift in gear and stops if I hit the gas good enough to romp on it. It will do it again if I merely press the gas.
