I've had an odd and disturbing thing happen twice now with my 2004 coupe with Steptronic. While cruising on the interstate at 60 mph or so in moderate traffic, I've floored the accelerator to pass. After an initial downshift, the transmission shifted up again to the original gear while the accelerator was still floored. It's only happened twice in about a year, but this could be quite dangerous if you're aiming for a hole in traffic and the car responds in this unpredictable way.

Has anyone else had this happen? Anyone have a clue as to the cause?
