Another thing is try cleaning the Idle air bypass system. A sticking IAC can cause exact problems you describe.
I have the E4OD Transmission. The truck engine would rev up a bit when I would put it into Reverse, but the truck didn't lurch-jump when put into gear. Hmm.
I think I'm going to check the transmission fluid level and attempt to clean the IAC before I drive into the Torque Converter possibility. Crossing fingers...
