sort of, if I stand on either passenger side of the truck I can hear the rattle pretty good. Drivability is fine, and the sound goes away after a while. I notice that when idliing the sound comes and goes as well. Maybe it is by pure coincidence that this happend during the jump ?ntech wrote:is it a rattle coming from the transmission area? (lay underneath and listen near the trans oil pan) If so, You may have put the trans into a perm. fail safe. I seen one not too long ago. Any lights on or driving problems?
