I just got my first BMW, had it checked out and everything was fine. Now that the winter has finally rolled around the Automatic Transmission Warning light is coming on. This does not happen when I start it or when it is running, but once I get to my destination I shut off the car and try to pull the key out and it is stuck, then the light comes on, then my key will come out. The light will remain on until I lock the car and then gone until the next time I reach my destination. So far this has only happened 3 of the last 5 times I've parked, it was around 33 degrees and the destination was short enough that the engine didn't heat up enough to register on the temp gauge. The car only has just over 65k on it so this seems odd to me... Any advice?
