Power goes through the No. 1 clutch (FOR-
WARD) or the No. 2 clutch (REVERSE) to the
No. 3 and No. 4 carrier (1). Because the No. 4
clutch (5) is engaged and holding the ring gear (6)
for the No. 4 clutch, the planet gears (4) (turned
by the No. 3 and No. 4 carrier) make sun gear (23)
turn shaft (20).
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.
