Methods of shifting gears

[Michael Hill]

I'd be interested if it were possible to use a linear electric solenoid to shift instead of a servo or pneumatics. The bad part is that they have maximum "on" times (duration the plunger can be "out"), which can be between 1 and 2 minutes or shorter (which is a problem in our application) because they need to cool down. It would be useful for teams who don't want to deal with pneumatics, especially if shifting would be their only use, and want to have fast shifting, because servos are sloooooow (in comparison)
