method is right, way of saying it isn't. 👍 The transmission trick is broken down like this:
Adjusting the final gear ratio (in this case, to shorten) initially and then moving the max speed autoset to get a new set of super-close gearbox ratios and then adjusting the final gear again (this time, to lengthen) so your gearbox stays super close but gives you a better range of speed. 👍 It doesn't always have to be all the way to the right.
