You can actually just cut out a section of the transmission, and then attach to a stage with less torque and more speed. It's rather easy to do.
If you are a rookie team and do not have old FP transmissions to play with (so that you can open one up and poke around without worrying about destroying anything important), I am *certain* that a team in your area will have one that they can give you. If you can't find one locally, 1551 will happily mail you one.
