Shakes or Wobbles problem
2007 Pontiac Grand Prix 6 cyl Automatic 82000 miles

my car jerks so hard it feels as if someone has hit me from behind. it is starting to occur more often and the jerking is much harder everytime. I took it to a repair shop and asked to have this checked and they stated they did not get the same reaction. could this be the transmission or what is this?

It does sound like something in the drivetrain, transmission axleshafts, differential bearing.
