Input shaft.olutch.clutch.When the transmission is in FOURTH SPEEDFORWARD, No. 2 and No. 3 clutches are engaged.The No. 2 clutch holds ring gear (6) for the No. 2clutch stationary. The No. 3 clutch holds ring gear(9) for the No. 3 clutch stationary. Input shaft (23)turns No. 2 sun gear (4). No. 2 sun gear turns No. 2planetary gears (25).Since ring gear (6) is held stationary by the No. 2clutch, planetary gears (25 ) move around the insideof the ring gear. The movement of planetary gears(25) causes No. 2 and No. 3 carrier (7) to turn in thesame direction as input shaft (23).Since ring gear (9) is held stationary by the No. 3clutch, the movement of No. 2 and No. 3 carrier (7)causes No. 3 planetary gears (26) to move around theinside of the ring gear. The No. 3 planetary gearsturn output shaft (22). From the output shaft, powergoes through the output transfer gears to thedifferentials.3-34
