Hmmm you might be onto something there...because it does seem it just opens and closes solenoids on its own (notice that it works even when TCU dies?)...now this for the 604 might be good or bad depending your perspective...arent 1-2 shift and 3-4 suposed to have a modulation between shifts to make em smooth? yes performancewise the slip might be bad but dont know how good it is for our trans...

BTW the Auto is still faster than Stick (even in auto stick mode...once you shift stick a lot you should be shifting really fast though...but watch out with missed shifts) cause your brain still dosent need to do the following: accelerator release and modulate, clutch depress, gear select, clutch drop/modulate, accel....while auto stick is....press button......thats it (yah its not triptronic but oh well)
