I know what you're talking about and mine does that, too. The transmission freaks out for a second and doesn't know whether to up shift, down shift or stay.
The bump is something different, though, I think. Mine bumps no matter how smoothly I feather the gas pedal. Say you're accelerating casually down a straight, level road (that's where it's most noticeable). You reach 45mph and release the pedal to coast. At the point where the transmission disengages to coast, it bumps about one second after you release the pedal. So it's like this: release... one second pause... bump.
Then, you casually apply the gas again and, at the point of the transmission engaging, there's the bump again. It's as if the gears in the transmission don't fit tightly. Like there's space between the teeth or something. Or like you're pulling a trailer that has a 4" receiver with a hitch that has a 2" ball.
It's like the more you try to avoid the bump, the more it bumps.
