The "autostick" that the crossfire comes with is a true automatic transmission. This does not work as well as a tiptronic and no where like a sequential gearbox and definely not like anything like a Ricardo 7 speed, double wet-clutch transmission (shifts gears in 200 miliseconds).
When you hit the plus or minus there is a short delay before the shift. It even managed to shift on me in a low torque situation durning my test drive (wonder if it reverts to automode if there is not manual change over a given time).... It is the same as having a D 4 3 2 L but has a fancy +/-
It is much easier then trying to force your tranny into the traditional 4 3 2 L but shifts just as slow. It does allow you to have some more control over the shift points which would be good in some situations like autocrossing.
