I have found a plethora of gearbox designs that use solenoids to shift, but I'm looking for one/some that use a servo to shift. I might be looking in the wrong place, but I can't seem to find any. Could anyone here link me to where I might find some?

I haven't done enough research to be looking for something specific yet, but anything that may apply would be useful to me.

Thanks.
