Oh look I conceptually designed a superior transmission with no moving gears, only moving dog rings, and 6 speeds, 3 shift forks, 3 dog rings, 2 notches in each path of the shift drum. All gears on the dog ring side are floating on the shaft so they spin freely when not engaged, all gears on the other shaft are splined so spin with the shaft.
OH LOOK: You don't need snap rings with this design, you can use shouldered spacers between the shouldered bushes.
Do I win a prize? Why in the hell hasn't this been implemented yet? I cannot possibly be the first person to come up with it....
