Jerky transmission

Hey guys, I drive the car listed above it is the Wolfsburg edition to be exact.

Lately my car, out of no where just started to jerk from a complete stop and it does not always happen but it happens often. It happens usually when I accelerate from a complete stop to kind of rapidly. Once it happens time to time the car just jerks back a little bit and you here a metal clunk noise as soon as you accelerate on the car then it goes away. When I am driving at high speeds the car is fine. I do not think that is it a.

Oxygen sensor.
Catalytic converter.
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor.
Bad TPS (throttle position) sensor.
Bad or dirty MAF (mass airflow) sensor.
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump).
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve).
Bad gasoline (fuel contaminated with water or too much alcohol).
Dirty or worn spark plugs.
Bad plug wires.
Weak ignition coil.

Problem I think that it has to do with the transmission for sure. I am hoping that its just bad transmission fluids that need a flush. I do not remember when the transmission fluids where changed. Car has been on two big mileage trips, and has been running fine until now? Please help me out.
