For that matter, if you're asking that question this late, chances are you're pretty screwed.

We have a Continuously Variable Transmission up and running nicely. Our drivetrain consists of 6 motors (3 compose each left / right assembly.) with many custom made gears and belts. We get a very nice and well balanced blend of speed AND torque without the need to "change gears" so to speak, since it's continuously variable.
I don't believe that we "live" in a machine shop any more than most teams with shop access, but the point is that a decent transmission certainly is possible. Could we produce a CVT without shop access? Probably not. However, last year we did put a block of HDPE on two pins. The HDPE fit over the drill transmission switch and it was very easy to actuate with a small servo. Teams can and do produce transmissions such as this without shop access every year.
Why not push, zoom AND hope to do it better than everyone else? (Not that we will of course... Just *hope*)
