I've got an 03 Bravada with about 15K miles.
Upon moderate acceleration (pedal 1/2 the way down) there is a very regular "hesitation" at regular intervals. It also comes with a sound, which sounds like going over expansion joints on a concrete road, although the road in all cases has been asphalt.
Dealer says this is "normal backpressure" in the transmission and there is a TSB out on it indicating it is normal.
Anyone have this experience?
TIA.
