gears jumping??

my wife has a 96 accord with an auto tranny...when we come to a stop sign and make a full stop..it feels like the car goes on gears by itself. it's also hard to take off at first.{it slags} but after it picks up it drives fine.

What do you mean 'goes on gears'
And how many miles are on the car...
Have you ever flushed the tranny? If so, when?

car has 100,000 miles on her..tranny fluid was flushed about a month ago..if i'm driving and come to a complete stop. i can feel the tranny jerking like it's jumping from gear to gear..it's weird..it just wants to go when it's fully stopped...by the way, idle is fine so i know it's not the idle.
