PLANETARY TRANSMISSION

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.
