Second Speed Forward
When the transmission is in SECOND SPEED FORWARD, No. 4 clutch (16) and No. 2 clutch (12) are engaged. The No. 2 clutch holds ring gear (13) stationary.No. 4 clutch (16) holds ring gear (17) for No. 4 clutch stationary. Input shaft (22) turns No. 2 sun gear (29). No. 2 sun gear turns No. 2 planetary gears (28).Since ring gear (13) for No. 2 clutch is held stationary by the No. 2 clutch (12), No. 2 planetary gears (28) move around the inside of the ring gear. The movement of No. 2 planetary gears (28) causes No. 2 and No. 3 carrier (11) to turn in the same direction as input shaft (22).As the No. 2 and No. 3 carrier (11) turns, No. 3 planetary gears (27) turn. The No. 3 planetary gears turn ring gear (15) for the No. 3 clutch and No. 3 sun gear (26).No. 3 sun gear (26) turns output shaft (23). Ring gear (15) for No. 3 clutch turns No. 4 carrier (20).Since ring gear (17) for No. 4 clutch is held stationary by No. 4 clutch (16), No. 4 planetary gears (25) move around the inside of the ring gear.The movement of No. 4 planetary gears (25) causes No. 4 sun gear (21) to turn. The No. 4 sun gear turns output shaft (23).As a result, torque to output shaft (23) is divided through No. 3 sun gear (26) and No. 4 sun gear (21). From the output shaft, power goes to the transfer and bevel gears.Third Speed Forward
When the transmission is in THIRD SPEED FORWARD, No. 3 clutch (14) and No. 2 clutch (12) are engaged. The No. 2 clutch holds ring gear (13) for No. 2 clutch stationary.No. 3 clutch (14) holds ring gear (15) for No. 3 clutch stationary. Input shaft (22) turns No. 2 sun gear (29). No. 2 sun gear turns No. 2 planetary gears (28).Since ring gear (13) for No. 2 clutch is held stationary by the No. 2 clutch (12), No. 2 planetary gears (28) move around the inside of the ring gear. The movement of No. 2 planetary gears (28) causes No. 2 and No. 3 carrier (11) to turn in the same direction as input shaft (22).Since ring gear (15) for No. 3 clutch is held stationary by No. 3 clutch (14), No. 3 planetary gears (27) move around the inside of the ring gear.The movement of No. 3 planetary gears (27) causes No. 3 sun gear (26) to turn. No. 3 sun gear turns output shaft (23).From the output shaft, power goes to the transfer and bevel gears.First Speed Reverse
