A transmission comprises an input shaft, an output shaft assembly, cylinder arm assemblies; and a rod-translation system. The input shaft comprises opposing input shaft ends, a rotation transmissive portion, and an axis of rotation. The transmissive portion extends intermediate the input shaft ends for transferring engine-originated rotational motion to the transmission assembly. The arm assemblies are concentric about the axis of rotation and comprise opposing arm ends, and an inner arm diameter. First arm ends are each independently geared to the transmissive portion via the inner arm diameters. The output shaft assembly comprises a stepped ring and an output shaft. The rod-translation system functions to translate a series of rods intermediate an arm-engaged position and an arm-disengaged position. First rod ends engage an output arm end when in the arm-engaged position for imparting rotational movement from the output arm end to the output shaft via the stepped ring.
