One thing that seemed to help was "resetting" the transmission (there is a feature that recognizes driver preferences and modifies shifting accordingly). When the car is off, turn the ignition so that the car has electrical power, but isn't running. Depress the accelerator all the way to the floor for a count of 30 seconds (you will feel a button under there). That's it. It wasn't exactly a magical fix, but I did notice a change. Adding transmission fluid (I had a slight leak) also helped.
