Stock shifts (non power mode) with the 4EAT aren't the quickest and I'm sure they must last at least 0.5 seconds. I wonder what happens to the 3 cyclinders that are shut down during that period of time???

All the DoD engines from GM and Chrysler use oil pressure to push out a pin and colapse half the hyrdallic lifters... the lifters then don't transfer any of the cam motion to the pushrods/valves. Also of course... they cut fuel/spark. Colapsing the lifters helps prevent pumping loses.
