Solved the jerk with a KUNFINE Car Electronic Throttle Controller, ($80) or you could use another brand (Pedal Commander $350) or another $80 brand. The controller ends the problem when set on ECO 3 or higher, or F1-2. Take a picture of the connector on your gas pedal and send it to the seller so they send you the correct connector. Adaptive memory reset only worked for a few days.
1) Turn the start switch to run, but do not start the car. All trouble lights are on and the fans in the heating and cooling systems are on if that was the position they were left in. Wait for chimes to stop.
2) Push the gas pedal all the way to the floor and hold it there for 10 seconds.
3) Turn the start switch to off with your foot still on the gas pedal.
4) Release the gas pedal, but do not put your foot on the brake pedal
5) Wait for 2 minutes before starting, or exiting your car.
IMO the problem is a bug in Chrysler's programming of the ZF 9HP48 transmission to respond to the gas pedal, but a controller will compensate for it. I never had to take it to the dealer. After three months I begin to occasionally feel hesitation so I plan to reset the transmission again.
