Hmmm But sometimes, like I said when its cold and Rpm is about 900 don't get that jerk. Trans shift smooth though. I was thinking more of the slack on the rear-end; between the pinion and Ring. Maybe if they make it tighter then it doesn't have so much slack on it. Just my opinionbradleyg said:Its normal....any auto trans could do this because when you shift you are changing the flow of the trans fluid in the valve body. In other words, taking the car out of drive and into park will change the oil flow from the drive circuit to a neutral circuit so you will feel a slight movement. You see the oil is pumped through the trans by the engine spinning the torque converter, which inturn attaches to the transmission's oil pump. When you rev the engine or when it is cold it idles faster so you get increased oil flow. So when you switch gears you get that "jerk" feeling. Do a search on google for the operating principles of auto trannys. All basically work the same reagarless of manufacturer.
