Abstract
An automatic transmission comprises a transmission mechanism including plural planetary gear sets, a transmission case storing the transmission mechanism, and an end cover closing an opening at one end of the transmission case. A planetary gear set disposed the closest to the end cover is assembled in such a manner that before the end cover is attached to the transmission case, a sun gear is assembled to the transmission case and a pinion carrier is assembled to the end cover. A thrust washer is disposed between an end face of the sun gear and an end face of an inner peripheral portion of the pinion carrier. The thrust washer is a member for adjusting a gap which is formed in an axial direction in the transmission case, and the member is selected from plural ones which have different axial thicknesses from each other.
