Automatic does not start

Automatic does not start
After a jock at the drive, my car hardly goes:
It's the Autom. on 2.3 or D and you give from the stand gas to drive, the engine turns normally high around but nothing else happens,
After 15 sec there is a jerk and the automatic indicator lights up "to the right" and the emergency program runs (third gear).

If I change the automatic but on 1 the car drives completely normal and I can then switch to D, the vehicle drives normally incl. power etc.
The game starts from the beginning until the next start.

Lt Audi has been refilled insignificantly ATF, the problem persists and you don't know what that might be about right now. Lt error memory gives a permanent message from the "Schieberkasten" (the valve of the Autom. Audi tries to cancel the power plans, but also asked me for help.

Björn H. I don't know the outcome.
Please help me
