To get the vehicle moving from a standstill, the
operator moves the gearshift lever into first. The main
shaft first-reverse speed gear is slid into position,
meshing the gear with the countershaft first-speed
gear. The countershaft first-speed gear and main shaft
first-reverse speed gear transmits power to the main
shaft (fig. 4-20, view B). Gear ratio is approximately
7.55 to 1.
