1) Is a seamless shift gearbox the same as a CVT (continously variable transmission? SEQUENTIAL

2) Do drivers have to shift gears themself. YES, right paddle UPshift, Left Paddle downshift

3) How many gears do these transmission have? 6 for road cars, 7 for F1 cars

4) Do they have discreet ratios? Road cars, yes, for the most part. Race cars the gear ratio is depended on the race circuit.

The above statement is not correct AU N EGL is only talking about a sequential gearbox the Zeroshift is explained by Monstrobolaxm correctly. Basically 2 gears are selected together then I would think there are various way of changing to the second gear. There was talk of fitting 2 clutches in the gear box to select each engaged gear not sure if this was banned. Basically the Zeroshift means zero time that the gearbox is not driving the car. What has changed is the time it used to take for the selector ring to disengage from one gear and engage in the next gear.
