A carrier assembly for a planetary gearset of a transmission includes a pinion carrier, a one-way brake having a rocker ring integral with the carrier and having multiple pockets mutually spaced about an axis and located on an outer radial surface of the carrier. A cam ring includes multiple notches angularly spaced about the axis and facing the rocker ring. A rocker, located in each pocket, pivots about a pivot center to engage the cam ring, and a spring urges each rocker to pivot toward engagement with the cam ring. A hydraulically actuated friction brake secured to the carrier alternately holds the carrier against rotation relative to a housing and permits the carrier to rotate.
