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.

With our pneumatics, we can only go all the way out all the way in or no air presssure and ram the wedge at a 90 degree angle to push the the cylinder into 2nd. It only gives us three postitions, therefore eleminating the possibility of a neutral. If we used other methods like a lead screw or what you atre describing, yes, we could have neutral position. Our original plan was for a leadscrew and a pto actuall, we scrapped it to geta faster lighter shifter.

Brad will post an inventor soon I think.

Thanks for the comments, questions, and suggestions. We are always eager to answer more.
