I too would love to see a more detailed drawing of the inner slider that pushes the balls up.

It seems that it should be possible to design this slider so that there is a neutral in between each gear, where all the balls are retracted. This would make it easier to synchronize the rpm of the input and output shaft for smooth shifts, as described in my earlier post.

It should also be possible to design an electromechanical, sequential shifter using an electric solenoid. This would likely be lighter and faster than a pneumatic shifter. I'll see if I can some up with something.
