1.On Volkswagen models the Atm is shifted by reading the different values from various sensors.If any one of the sensor is malfunction the shift jerk can occur.
2. The other possible cause is the ATM oil is not changed for a prolonged time, if it is so don't change the ATM Oil at once , keep the Old Oil and replace it little by little, otherwise your ATM will not shift.
3. Worn out or damaged ATM Parts,like solenoid valves,valve body etc... If so need overhaul for ATM.
