Autobox Problem

[bigwil1947]

Hi i have a problem with my galaxy mk 3 autobox 08 tdci.When you come to stop, it is still in continous drive, like if you need to press the clutch in.Which you cant do as its a auto,You have to knock it out of drive to stop it,as braking causes the car to judder and stall as the car is still in drive.I had to drive the car home for some 130 miles ,it drove perfect until i was coming to a stop i can then  select drive and away it goes again, Any ideas??????
