Slight Roughness Each Morning

[OldGuy]

Each morning when I first drive the car out of the driveway and up the hill (I let it warm up for a moment or two first), there is a rough feeling as the car shifts. It is less noticeable if I accelarate a bit harder, which I would rather not do until the car has fully warmed up. It feels like the shifting is hesitant----I don't think it's in the engine. Other posts have also mentioned this. I've now passed 5,000 mi. on my '09 automatic and, although the problem hasn't worsened, it hasn't gone away either. Is this a permanent characteristic of the 7 speed automatic transmission? Has anyone had a dealership check it out on his car? By the time I arrive at my dealership, the car is fully warmed up and the problem is gone.
