Abstract
A 16-speed drop box transmission is provided in a particularly compact double-diamond arrangement. Most of the shafts in the transmission, as well as many of the gears and clutches, are identical and interchangeable. This significantly reduces the number of different parts needed to make the transmission. Most of the gears which do the actual power modification to produce the various gear ratios are rotatably mounted about these interchangeable shafts. The basic design is highly flexible, since different gears may easily be substituted for one or more of these rotatably mounted gears to produce a transmission with different gear ratios.
