"Design of a semi-automatic four-speed transmission for automotive engines with moderate horsepower is described. The basic configuration consists of main and countershafts and five pairs of constant-mesh gears. Engine torque is transmitted through an input gear pair to the countershaft, and finally to the output shaft through a selected output gear pair. Selection is accomplished by engaging one of five hydraulically operated clutches located on the countershaft. Engagement fixes the desired gear to the countershaft and engine torque is then transmitted to the mating gear, which is fixed to the output shaft. Fourth speed is obtained by coupling the input shaft directly to the output shaft through a sixth clutch. Design of clutches, gears, shafts, supply pump and control valves is analyzed in detail. Requirements for a master clutch, for use during acceleration from rest, are summarized"--Abstract, page ii.
