When harsh shifting occurs after parking for extended periods, it is most likely due to the shifts solenoids. Remove them to check for stiffness and clean them if dirty.
If the transmission fluid had not been replaced for some time, check its condition and replace if necessary.
Harsh shifting can cause premature wear to components such as engine mounts and clutches so an earlier remedy would be less costly.
Btw if the harsh shifting is only when you shift to D or R after starting up and does not jerk hard when upshifting to other gears, it could mean abad engine mounts. When starting from cold, the idling speed would be higher and when shifting is done during this time, it would jerk if the engine mounts are bad.
