" When the throttle is open wide, as during accelera-
tion in the low-speed range, the forward clutch,
one-way clutch (3-4) and one-way clutch (1-2) oper-
ate to prevent the rear internal gear from turning in
the reverse direction .
While coasting, the rear internal gear turns normally
and the one-way clutch (3-4) is released and idles .
Therefore, no power is transmitted and the engine
does not provide braking action .
During deceleration, the overrunning clutch is ap-
plied and the one-way clutch (3-4) is prevented from
idling ; however, since the one-way clutch (1-2) is
released and is idling, reverse power is not transmit-
ted and engine braking is not performed.
