To select any gear (ie 1st gear) the other two levers (3/4th & reverse) must be in the neutral (center) position. Other sections are added in a similar way: parts are pressed into casings, gears are added, and sections are bolted together in a repetitious manner. The counter shaft has fixed associating gears that are permanently meshed with the loosely connected gears on the output shaft. Thus a 1:1 ratio is achieved. The ST1200 also utilizes aircraft quality bearings where the pure-race CS2 uses aerospace spec components. Adjustment: transmissions, Both transmissions are available in 2,3, 4 or 5 speeds.
