ABSTRACT:
An automatic transmission having a one-way brake in which an outer race is fixed to a rotational member of a planetary gear unit or to a transaxle case and, conversely, an inner race is fixed to the transaxle case or the rotational member of the planetary gear unit, characterized in that the rotational member is provided with an oil infeed plate co-rotatable therewith. Oil dispersed from the input shaft of the transmission is introduced to the one-way brake by pressure produced by the centrifugal force of the rotating oil infeed plate. Thus, burn-out of the one-way clutch is prevented since the clutch is sufficiently lubricated at the time of overrun.
