ABSTRACT OF THE DISCLOSURE A transmission that uses a gear set in the form of a pair of gears stacked rigidly together to couple a driving gear to a driven gear has its ratio determined by the relative number of teeth of the stacked gears and the gears with which the stacked gears mesh. If the number of teeth of either or both gears in the stack is varied, the axle of the stack must be moved to a different location in order to keep all of the pairs of gears meshed. The transmission has two or more axle-receiving locations to receive the axles or stacks effecting different ratios. To simplify assembly, the stacks are color-coded according to the ratios they effect. Stacks of the chosen color will only fit in one axle location. The selected stack may be enclosed in the transmission housing so that its color code will not be visible after assembly of the transmission. In order to be able to identify the gear ratio of an assembled transmission, another transmission component, such as an axle, which is installed in the assembly at a location where it may be seen from outside the finished transmission, is also color-coded in the same way as the gear stack.
