Transmission Not Go Into Gear problems of the 2016 Chrysler 200

The vehicle will stall while driving causing you to stop, place in park and restart. Upon trying to restart it struggles to turn over. Seems to be happening with the car has sat for awhile and is cold. The temp gauge shows nothing on it. I know the car will stall. If there is a line or more on the temp gauge on the dashboard it doesn't seem to have any issues. The vehicle is also not shifting from gear to gear properly. It seems to not catch when it should go to the next gear. The car will jerk.

Went to a store with a heavily sloped parking lot. Approximately 15 to 20 degrees. Parked car and went in side, returned to the car, started, and placed car in reverse, looked behind me for pedestrians and notice some people down a little ways. . Proceeded to carefully pull out of the slopping parking space in reverse. Applied slight pressure to brake pedal to shifted car into drive. Removed foot from brake to apply foot to gas pedal with a little more pressure than usual due to the slop, to keep car from rolling backwards. . The car keep rolling in reverse due to the declining slop of the parking lot. Car did not engage into drive and the engine revved up to high rpms and if not for a fast reaction from me returning my foot to brake after realizing what was going on, I could of easily ran into the people that I noticed earlier. Not good! when I put my foot on the gas peddle to stop the car, the car went into gear and the car shook violently due to the high rpms. The people in the parking lot were also startled. This is the primary car for my wife and I asked her if the car has not gone into gear before. To my astonishment she said once. This car now sits in the garage awaiting the Chrysler dealer to pick it up 27,997 miles. This kind of problem could easily do harmful bodily injury to a pedestrians or my wife. .
