Rotor Transmission Planetary (1) Number one clutch (second gear) (2) Number two clutch (first gear) (3) Number three clutch (third gear) (4) Output housing (5) Planetary carrier (6) Output shaft (7) Front ring gear (8) Relief (9) Hub (10) Front planetary pinion gears (11) Sun gear (one piece with two sets of gear teeth) (12) Rear planetary pinion gears (13) Input ring gearPower from the engine goes through the flywheel to the rotor transmission. The transmission is coupled to the flywheel and there is not a torque converter. The connection is made with a spring coupling.The transmission contains three speeds. The transmission also has two sets of planetary gears (10) and (12). Only one clutch is engaged per rotor speed.Power Flow in First Speed

(4) Output housing (7) Front ring gear (10) Front planetary pinion gears (11) Sun gear (one piece with two sets of gear teeth) (12) Rear planetary pinion gears (13) Input ring gear (14) Input shaftPower enters the transmission through input shaft (14). Input shaft (14) is splined to input ring gear (13). Power is transferred to sun gear (11) and through front planetary pinion gears (10). Number two clutch is pressurized. Number two clutch holds front ring gear (7) in place. Front planetary pinion gears walk around the inside of front ring gear (7), which is being held. Power is transferred out through housing (4). Number three clutch housing (4) is splined to output shaft (6). Power is transferred from the transmission through output shaft (6) .Power Flow in Second Speed

(4) Output housing (6) Output shaft (9) Hub (10) Front planetary pinion gears (11) Sun gear (one piece with two sets of gear teeth) (12) Rear planetary pinion gears (13) Input ring gear (14) Input shaftPower enters the transmission through input shaft (14). Input shaft (14) is splined to input ring gear (13). Power is transferred to planetary pinion gears (12) and front planetary gears (10) will run. Number one clutch is pressurized. Number one clutch holds hub (9) of sun gear. The sun gear has splines that hold sun gear (11). Front planetary pinion gears (10) walk around sun gear (11) and power is transferred out through clutch housing (4). Number three housing (4) is splined to output shaft (6). Power is transferred from the transmission through output shaft (6) .Power Flow in Third Speed

(4) Output housing (6) Output shaft (13) Input ring gear (14) Input shaftPower enters the transmission through input shaft (14). Input shaft (14) is splined to input ring gear (13). Number three clutch (4) is pressurized. Number three clutch holds ring gear (13) to output housing (4) of the number three clutch. Number three clutch housing (4) is splined to output shaft (6). Power is transferred out of the transmission through output shaft (6).
