There is also the possiblitly of the valve body gasket blowing out and causing loss of vacuum in the tranny. That is what happened to mine @ 100,000 miles. Transmission problems are best left to a pro. The basic thing you should concern yourself with is the Transmission Fluid. A higher, or lower level can cause shifting problems. Or of course, if the transmission fluid is dark or burnt, that can mean transmission problems too. But make sure the level is ok. If the fluid is ok, i'd get it inspected at a trusted transmission shop. Usually problems in transmissions start small, and if you catch them they can be remedied. Best of luck.

would an automatic transmission car jerk when shifting after having had a transmission flush
possibly the throttle position sensor the sensor will also change the shifting pattern

If your transmission is not shifting into third gear and overdrive it could be a parking pawl. This prevents the transmission from rotating.
