A new idea I have been toying with for shifting is totally inspired by a local Transmission builder-Liberty's Gears- in Taylor Mi. They build custom Drag Racing Trannys that you can shift effortlessly under full throttle accelleration. Their design has a synchronized 1st gear, the rest are unsynchro'd. The way it works is very simple. The "slider" has only 12 teeth with a .500 gap in between each tooth. On the face of the gear upon which the slider grabs, there are 12 matching teeth with the same gap. The front edge of the teeth have a lead in angle cut into them to help "grab" the slider. I had this modification done to my Ford Toploader that I ran in my Camaro 10 years ago. They call it "Pro Shifting" and let me tell you, I could shift the trans under full power @ 7800 rpm!! I'm sure if I apply that same technology to our planetary, we'll be shifting even smoother than we do now. With the amount of play that is inherent in that design, having the slider only partially engaging in low should go away. Sometimes ours will not go fully into low because there is a neutral position between the 2 planet sections abd the slider is "floating" momentarily. This has to be, since you cannot be simultaniously in high and low. Pneumatics, to me are a better way to shift. It requires less code, and is virtually trouble free. I suppose you could shift usig a Globe motor. You'd have plenty of power, but still need more code than pneumatics. Just my 2 sense...
