I saw a post some weeks ago about someone who couldn't move thier car from a stop! I discovered that when your auto trans has a problem it goes into a "safe" mode and registers the issue for the Techs to check later. Although the car still runs, it will not move. Apparantely, you should shut off the engine, put it in park for at least 10 seconds and then restart the engine. You should now have use of reverse and second gear so that you can limp home or to a DC dealer. Sorry, I didn't see this earlier. Maybe it will help someone in a fix.
