Didn't read it fully that happens. Check for a broken motor mount or trans mount it may be the engine rocking when torque is applied to move the truck or when it's shut off. To check hold foot on brake and put in drive, give some fuel and if motor lifts way up themount on left side is broken do the same for reverse, do this where there are no other vehicles/people around incase something happens. If the motor lifts more than an inch or so the mount on that side is broken for trans mount see if trans can be lifted at rear while still in vehicle.
