If you look at the top of the picture you can see what we call "dogs" between the gears. The dog in the middle is attached to the shaft which is moved by the pneumatic cylinder. The cool thing is that the dog is made so it will engage every time. It would all make much more sense if we had video.
Yeah, I was looking at this, it looks pretty neat actually. What do you use to allow the "dog" to interface with the shaft?

This system would be the easiest to create a 4 speed with, because you'd have the motors going to the 1st shifting stage, then I'd put a 1:1 gear ratio on the outside of the 1st shifting stage to another shaft. This shaft would have the 2nd shifting stage which is geared to the final output shaft.
