The most common cause of a automatic transmission jerking, when shifting, is low Transmission Fluid. Fill the transmission to the full mark.
would an automatic transmission car jerk when shifting after having had a transmission flush

Depends. Most likely cases: On a standard: Poor shifting on the driver's part. On an automatic: Transmission problems, get it checked.
The year, make, model, transmission and engine info would help but it is probably the transmission down shifting if the vehicle is an automatic.
If it's an automatic, your transmission may be dying; if you drive a manual, you're probably letting the clutch out too fast.

Its normal for most manual cars the clutch is basically shifting gears in the engine but if you are accelrating shifting gears higher it could jerk a little bit so it can lock the gear and preset the engine to the desired gear Now if this is an automatic here you are not hitting the brake pedal fully Transmission fluid is low or empty Or it can be just old so it can jerk a bit to get into gear... however it is potentially bad for an automatic car because it has more parts and the thing it would do the most harm to is the gearbox.
your transmission wears after time, try getting a fluid change, use fluid made for older cars this should help slow down wear and make the jerk much less noticeable
It definitely is a possible cause of it jerking, if it's not an engine mount, service the transmission
Poor driver or bad transmission.
possible problems: broken engine mounts cause the engine to jerk, or tranmission fluid needs change, and possibly bad transmission.
The "lockup torque converter" could be engaging too soon. Take it to a transmission shop to have it diagnosed.
