I first have to make my own interpretation of jump, and wonder if it is even a transmission concern. If you try power braking it, with the vehicle in drive, and firm brake pressure, apply some throttle. Do you feel the same sensation at any time? If you do, it sounds like an ignition misfire. Is there a check engine light on, If so I would have the codes read and a diagnostic path may be determined from that.
