I have always looked up to team 222 for the way they build their transmission. Specially the shifter.

Just like Henry pointed out before me, that you can shift with globe motors. Team 233, The Pink Team used globe motor to shift or I was told. Take a look at their machine if you get a chance. Or get in touch with someone from their team.

I got it. Don't bother with rubber cement or anything. Just put wide rubberbands on your polycarb/acryllic gear-wheels. Make sure you get your center to center distance right though for good contact between the rubber bands. Enough contact to hold, but not excessive friction/binding.
