CONTROL GP 10R5886 - Caterpillar

Third Speed FORWARD
When the transmission is in third speed FORWARD, No. 2 and No. 3 clutches are engaged. No. 2 clutch (10) holds No. 2 ring gear (11) stationary. No. 3 clutch (12) holds No. 3 ring gear (13) stationary. Input shaft (20) turns No. 2 sun gear (27). No. 2 sun gear turns No. 2 planetary gears (26) .No. 2 ring gear (11) is held stationary by No. 2 clutch (10). This causes No. 2 planetary gears (26) to rotate inside No. 2 ring gear (11). The movement of No. 2 planetary gears (26) causes No. 2 and No. 3 carrier (9) to turn in the same direction as input shaft (20) .No. 3 ring gear (13) is held stationary by No. 3 clutch (12). Then, the movement of No. 2 and No. 3 carrier (9) causes No. 3 planetary gears (25) to rotate inside No. 3 ring gear (13). No. 3 planetary gears (25) turn No. 3 sun gear (24). No. 3 sun gear turns output shaft (21). From the output shaft, power goes through the transfer and bevel gears to the steering differential, the brake unit, the planetary, and the brake unit.First Speed REVERSE

No. 1 clutch (8) holds No. 1 ring gear (7) stationary. No. 5 clutch (18) holds hub (19) stationary.Input shaft (20) turns No. 1 sun gear (30). No. 1 sun gear turns No. 1 planetary gears (29). No. 1 carrier (31) has a direct mechanical connection with No. 1 ring gear (7) .No. 1 ring gear (7) and No. 1 carrier (31) are held stationary by No. 1 clutch (8). The movement of No. 1 planetary gears (29) causes coupling gear (28) to turn in the opposite direction as input shaft (20). Coupling gear (28) has a direct mechanical connection with No. 2 and No. 3 carrier (9). As the No. 2 and No. 3 carrier (9) turns, No. 3 planetary gears (25) turn. The No. 3 planetary gears turn No. 3 ring gear (13) and No. 3 sun gear (24). No. 3 sun gear turns output shaft (21). No. 3 ring gear
