Abstract
Automatic transmission 1 includes second friction plates 17 connecting a second drum 27 to a second hub 37, a second engagement hydraulic chamber 67, a second centrifugal balance chamber 77, and a second piston 47 engaging and disengaging the second friction plates 17. The second centrifugal balance chamber 77 overlaps the second friction plates 17 in the axial direction in the automatic transmission 1. The automatic transmission 1 further includes a second oil passage 9 for discharging hydraulic oil in the second centrifugal balance chamber 77 to a position not overlapping the second friction plates 17 in the axial direction.
