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).
Shaft (20) turns hub (16) for the No. 7 clutch.
The No. 7 clutch (18) is engaged and makes the
ring gear (15) for the parking brake turn with hub
(16). The ring gear (15) for the parking brake is
