So I will be taking it back in next week for further diagnosis. Will follow up with the findings...

My guess is an internal problem with the transmission, possibly the torque converter going bad.

Not sure if torque converter is going bad in your case,but from majority of the forum members who experienced lurching including myself (not as severe as some stated) it is internal design and operation of this particular ZF transmission and its software. Try to adapt your driving style especially during start/stop intervals. Please, keep us posted!
