Another setup that I've heard of is using a window motor coupled to both transmissions with a spring setup to engage the gear if it is not lined up during the initial gear change request. I do not know what team had this setup, but it is definitely worth researching some more as it could offset the weight of a pneumatics system, even those with pvc air reservoirs.
Force = Pressure * Area. Much smaller force there.
