When the 1st gear is selected, the underdrive clutch, 
the one-way clutch (OWC-L), the low-reverse brake*, 
the reduction brake and the one-way clutch (OWC-
D) are participating. The driving force from the input 
shaft is transmitted to the underdrive sun gear via the 
underdrive clutch. The driving force transmitted to 
the underdrive sun gear via the output pinion turns 
the low reverse annulus gear clockwise and at the 
same time turns the output planetary carrier anti-
clockwise with the fashion that the output pinion 
revolves around the underdrive sun gear. However, 
since the one-way clutch (OWC-L) and the low-
reverse brake* are engaged at this time, the low-
reverse annulus gear is locked and the output plane-
tary carrier only rotates anti-clockwise. This driving 
force turns the direct pinion anti-clockwise via the 
direct annulus gear. Since the direct sun gear is 

locked by the one-way clutch, the direct planetary 
carrier rotates anti-clockwise with the fashion that the 
direct pinion revolves around the direct sun gear to 
obtain reduction ratio of the first gear. Since the out-
put planetary carrier is connected to the output annu-
lus gear, the overdrive pinion gear is driven at the 
same time. However, since the overdrive planetary 
carrier is locked by the one-way clutch (OWC-L) and 
the reverse sun gear is free to rotate, it runs idle and 
has no effect on the rotation of the output planetary 
carrier.
NOTE: *: The low-reverse brake is activated only 
when the vehicle is stationary (10 km/h or less) and 
in the sport mode.

When the 2nd gear is selected, the underdrive 
clutch, the second brake, the reduction brake and the 
one-way clutch (OWC-D) are participating. The sec-
ond brake is operated under the first gear condition, 
the reverse sun gear is locked and the driving force 
from the output annulus gear turns the overdrive 
planetary carrier anti-clockwise with the fashion that 
the overdrive pinion revolves around the reverse sun 
gear. Since the overdrive planetary carrier is con-
nected with the low-reverse annulus gear, the low-

reverse annulus gear also rotates anti-clockwise. 
This rotation of the low-reverse annulus gear is 
transmitted to the direct annulus gear via the output 
pinion, however, since the elements of the direct 
planetary gear are the same as that of the first gear, 
rotation amount of the low-reverse annulus gear is 
added to the rotation of the output planetary carrier to 
obtain the reduction ratio of the second gear.

When the 3rd gear is selected, the underdrive clutch, 
the overdrive clutch, the reduction brake and the 
one-way clutch (OWC-D) are participating. Since the 
overdrive clutch connects the input shaft with the 
overdrive planetary carrier and the low reverse annu-
lus gear, the rotation speed of the underdrive sun 
gear that is connected with the input shaft by the 
underdrive clutch and the rotation speed of the low-
reverse annulus gear become equal. Under this con-

dition, the planetary gear set is locked and rotates as 
one body to transmit the driving force to the direct 
annulus gear. The operation of the direct planetary 
carrier elements is the same as the first gear, there-
fore, the reduction ratio of the third gear is obtained 
by the configuration that the planetary gear set 
rotates as one body under locked condition.

When the 4th gear is selected, the underdrive clutch, 
the overdrive clutch and the direct clutch are partici-
pating. The operating condition of input shaft ele-
ments is the same as that of the third gear, where the 
planetary gear set is locked to rotate as one body. 
The driving force input to the output planetary carrier 
is transmitted from the direct annulus gear con-

nected with the output planetary carrier, via the direct 
pinion, to the direct sun gear and turns it clockwise. 
On the other hand, since the direct sun gear is con-
nected with the direct planetary carrier by the direct 
clutch, they rotate anti-clockwise as one body to 
obtain the reduction ratio of the fourth gear.

When the 5th gear is selected, the overdrive clutch, 
the direct clutch and the second brake are participat-
ing. The driving force of the input shaft is transmitted 
to the overdrive planetary carrier via the reverse 
clutch. On the other hand, since the reverse sun gear 
is locked by the second brake, rotation amount of the 
overdrive pinion that revolves around the reverse 
sun gear is added to the rotation of the overdrive 
planetary carrier and the resultant rotation is trans-

mitted to the output annulus gear. This driving force 
is then transmitted to the output planetary carrier that 
is connected to the overdrive planetary carrier and 
the direct annulus gear. Since the operating ele-
ments of the direct planetary carrier are the same as 
that of the fourth gear, the reduction ratio of the fifth 
gear is obtained by the revolution of the overdrive 
pinion.

When the reverse gear is selected, the reverse 
clutch, the low-reverse brake and the reduction 
brake are participation. The driving force of the input 
shaft is transmitted to the reverse sun gear via the 
reverse clutch. On the other hand, since the over-
drive planetary carrier is locked by the low-reverse 
brake, the driving force of the reverse sun gear is 
transmitted to the output annulus gear via the over-
drive pinion as the clockwise rotating force. This driv-
ing force is then transmitted to the direct annulus 
gear via the output planetary carrier. Since the direct 

sun gear is locked by the reduction brake, rotation 
amount of the direct pinion that revolves around the 
direct sun gear is added to rotate the direct planetary 
carrier clockwise. Thus the reduction ratio of reverse 
gear is obtained. At this time, the output pinion is 
driven by the output planetary carrier, however, since 
the underdrive sun gear is free to rotate, it runs idle 
and has no effect on the rotation of the output plane-
tary carrier.

In parking and neutral, all of the clutches are disen-
gaged and driving force from the input shaft is not 
transmitted to the planetary carrier. To enable a quick 
shift to 1st gear or reverse, the low-reverse brake 
and reduction brake is operational.
