I have a 1997 Dodge Stratus Es (Automatic) and I'm having some problems in the cold mornings. I drive out of the drive way in reverse put it in drive then my car doens't move. Ill press the gas and the rpms will go up and my car wont move. Ill switch it through park neutral and drive then ill press the gas it makes a jerking motion then it goes and runs like normal. What could the problem be?
