Truck ha 60 miles, v6 with tow package.
In last few weeks maybe every two to three days while sitting stopped at traffic lights the truck "bumps". I thought the car behind tapped me the first couple of times it happened. Have had the transmission and rear end serviced at dealer at 40 miles. Love the truck - stereo volume at head unit goes crazy, researching sound systems.
Anyone expirienced the "bump"?
