Synchronizer assembly (22) Cup (23) Shifter fork (24) Sliding collar (25) Blocker pin (26) Split pin (27) ConeThe torque converter turbine drives input shaft assembly (1). The operator moves the direction control lever that is mounted on the steering wheel column to the reverse position, engages the reverse clutch. The oil pressure is sent through input shaft assembly (1) to pressurized reverse clutch piston (7). The reverse clutch pack (8) engages and the clutch pack sends power to the reverse input gear.Reverse input gear (10) transmits the power to reverse idler driven gear (9), which turns reverse idler shaft (6) and reverse idler input gear (3). Reverse idler input gear (3) transmits the power to driven gear (19), which turns countershaft (20), which is constantly engaged with the speed range gears. The countershaft will rotate in the reverse direction.The countershaft is in constant mesh with speed range gears that are mounted on output shaft (18). The neutralizer button that is located on the shift lever must be activated in order to neutralize the solenoid control valve of the transmission. This engages first speed gear (12) or second speed gear (14) with output shaft (18). Activating the neutralizer button releases a direction clutch and the button places the transmission NEUTRAL. The shift lever can now be moved into first gear or second gear. Shifter fork (23) slides synchronizer collar (24) to the right so first speed gear (12) engages with output shaft (18). Also, the shifter fork (23) can slide the synchronized collar to the left so second speed gear (14) engages with output shaft (18) .If there is no torsional load or mismatch of speeds between the speed gear and the output shaft, synchronizer assembly (13) will engage the speed gear with the output shaft. Once the shift is complete the
