VALVE GP-SOLENOID 2441743 - Caterpillar

Third Speed FORWARD
When the transmission is in third speed FORWARD, No. 2 and No. 3 clutches are engaged. The No. 2 clutch holds ring gear (5) for the No. 2 clutch stationary. The No. 3 clutch holds ring gear (7) for the No. 3 clutch stationary. Input shaft (14) turns No. 2 sun gear. No. 2 sun gear turns No. 2 planetary gears (20) .Ring gear (5) is held stationary by the No. 2 clutch. This causes planetary gears (20) to rotate inside the ring gear. The movement of planetary gears (20) causes No. 2 and No. 3 carrier (3) to turn in the same direction as input shaft (14) .Ring gear (7) is held stationary by the No. 3 clutch. Then, the movement of No. 2 and No. 3 carrier (3) causes No. 3 planetary gears (19) to rotate inside the ring gear. The No. 3 planetary gears turn No. 3 sun gear (18). No. 3 sun gear (18) turns output shaft (15). From the output shaft, power goes through the transfer and bevel gears to the steering clutches and brakes.First Speed REVERSE

The No. 1 clutch holds ring gear (1) for the No. 1 clutch stationary. The No. 5 clutch holds rotating hub (11) stationary.Input shaft (14) turns No. 1 sun gear (24). No. 1 sun gear turns No. 1 planetary gear (23). No. 1 carrier (25) has a direct mechanical connection with ring gear (1) .Ring gear (1) and No. 1 carrier (12) are held stationary by the No. 1 clutch. The movement of No. 1 planetary gears (23) causes coupling gear (22) to turn in the opposite direction as input shaft (14). Coupling gear (22) has a direct mechanical connection with No. 2 and No. 3 carrier (3). As the No. 2 and No. 3 carrier turns, No. 3 planetary gears (19) turn. The No. 3 planetary gears turn ring gear (7) for the No. 3 clutch and No. 3 sun gear (18). No. 3 sun gear turns output shaft (15). Ring gear (7) turns No. 4 carrier (12). As the No. 4 carrier turns, No. 4 planetary gears (17) turn. The No. 4 planetary gears turn ring gear (9) for the No. 4 clutch, which is connected to housing
