While second gear is in use and the odd shaft's clutch is open, shift to third for the next shift. Continue on up to top gear.

If wet clutches are used the only penalty is the oil pump. If dry clutches are used you have identical losses (small) to a manual trans, over 95% efficiency. Give the driver shift paddles if he wants to be in charge, but override for engine overspeed.

All that complexity and expense and for what? Gimme a plain ol' 5-speed.
