Transmission jerks like you have been rear ended when accelerating. Also right before coming to stop, clunks into gear. I have done the following: new transmission fluid, software update, disconnected and reconnected the battery. No solution found.

My car has 74000 miles.
My car has an automatic transmission.

Below is a process to follow after reprogramming transmission module or disconnecting battery so the TCM can relearn shift points. If after following the below service then seek a mechanic like one from Your Mechanic to continue further diagnosis of problem to see if it is internal transmission or module problem.
