I wonder if one could shift a 2 speed with one of these....

I think the GDC is a little more sophisticated than that. I believe they purposely left out the @12v since it is unlikely that you would use a solenoid at 100% duty cycle in a FIRST robot. Solenoids have a wattage rating based on the heat they can dissipate that is independent of the voltage used to power them.

As far as using them to shift a 2sp gear box keep in mind that a solenoid is designed to either push or pull but not both. So using one you would only be able to shift once. Now if you had one where you could link the pintles, IE the pintle of a "pull" solenoid hooked to the back of a "push" solenoid, then you could use them to shift back and forth between gears.
