Well, I knew that at some time I had seen Dad working on trannys that had sliding gears, but it could have well been John Deere tractors, for all I knew...
I guess the pertinent thing now is, would it help the Geo Metro trannys that the folks are using that are going clutchless? I know they are having to rpm-match to change gears, similar to the way the truck drivers do...
First gear is pretty useless for some of them, so it could be ground down to save mass, for that matter. Many of them are starting in second and going to third, but I'm guessing those are using a different fork in the Metros...
...and we probably should be posting this in some type of modification thread, now that we're practically done with it...
