ABSTRACT:
In a transmission, an input set of rotatable gears is meshed with an input gear that is fixed to an input shaft which receives input. Through an arrangement of shafts and gears, any selected rotatable gear of the input set can be fixed to its shaft and drivingly connected to any selected one of a set of gear ratio combinations that are formed using a plurality of the gears in order to provide speeds at an output end of an output shaft for output. A gear ratio sequence, formed by drivingly connecting a plurality of the gears, provides a decrease in speed for at least one of the gear ratio combinations and an increase in speed for at least one other of the gear ratio combinations. A middle range of speeds for the output includes at least one speed that is lower than at least one of a low range of speeds for the output and at least one other speed that is higher than at least one of a high range of speeds for the output.
