1. A multi-speed transmission, comprising:
an input section comprising a plurality of input speed reduction gearsets;
an intermediate section comprising a plurality of clutches and gears configured to generate different speeds; and
an output section comprising a high clutch and an eighth gear arranged on a fifth shaft, a low clutch arranged on a fourth shaft, and an output gear arranged on an output shaft, wherein operation of the high clutch and the low clutch is coordinated such that, when the high clutch is active, the low clutch is inactive and, when the low clutch is active, the high clutch is inactive, wherein
each of the sections is arranged in a transmission housing, wherein a layout of the sections arranged in the transmission housing is in a short drop layout with a first distance between an input shaft of the input section and the output shaft of the output section or in a long drop layout with a second distance between the input shaft and the output shaft, and wherein the second distance is greater than the first distance.
