PLANETARY TRANSMISSION TM 5-3805-263-14&P-2 SYSTEMS OPERATION Power goes through the No. 1 clutch (FOR- WARD) or the No. 2 clutch (REVERSE) to the No. 3 and No. 4 carrier (1). The planet gears (4) are turned by the No. 3 and No. 4 carrier (1). The planet gears (4) are engaged with the ring gear (6) for the No. 4 clutch and make it turn. The No. 4 clutch (5) is not engaged but the ring gear (6) for the No. 4 clutch is connected to the No. 5 carrier (7) with a spline. Because the No. 5 clutch (9) is engaged and holding the ring gear (8) for the No. 5 clutch, the planet gears (25) (turned by the No. 5 carrier) make the sun gear (24) turn shaft (20). As the sun gear (24) turns shaft (20), it gives resistance to the planet gears (25) and to the No. 5 carrier (7). The ring gear (6) for the No. 4 clutch is connected to and has resistance to turning by the No. 5 carrier (7). Because the ring gear (6) for the No. 4 clutch has a resistance to turning, the plant gears (4) (turned by the No. 3 and No. 4 carrier) make the sun gear (23) turn the shaft (20). Power is divided between the sun gear (23) and the ring gear (6) for the No. 4 clutch. Sun gear (12) turns with shaft (20) and makes planet gears (27) turn. Because the No. 6 clutch (11) is engaged and holding the ring gear (10) for the No. 6 clutch, the planet gears (27) (turned by the shaft and the sun gear) make the No. 6 carrier (13) turn. The No. 6 carrier is connected to the ring gear (15) for the parking brake which is connected to the output flange (17) and power is sent to the differential. 2-6
