ABSTRACT:
In a planetary gear train of automatic transmission, there are disposed two one-way devices which are parallelly but reversedly arranged between the input shaft and a sun gear. Due to the flow-cut function of one of the one-way devices, the high speed rotation of the sun gear caused under a certain speed condition of the transmission is not transmitted to a clutch drum of the associated clutch device thereby to prevent the clutch device from malfunctioning.
