Thank you for choosing Just Answer! all of the above codes except for the T072 are for when the PCM/engine control module has lost power. These codes generally appear if the battery has been unhooked or replaced recently. (have you disconnected the battery recently?) Also the T072 code is the major culprit. That code on sets if there is an internal fault to the engine control module and the fix for that is to replace the ECM. A faulty module can certainly cause an issue with a jerking feeling as it controls the engine operation as well as provide information to the transmission. Under what conditions does the jerking occur as in what speeds, only when it shifts, just at cruising speed? I suspect the jerking is caused by the faulty ECM but was curious about the exact details of the jerking.
