Abstract
A carrier assembly for an automatic transmission includes a first plate, a second plate spaced along an axis from the first plate, a third plate spaced axially from the first plate and the second plate by angularly spaced legs, the third plate being formed with angularly spaced recesses. Short pinions, supported on the first plate and the third plate, each has a major diameter sized to move between at least two of the legs along a chordal path into one of the recesses during installation in the carrier. Long pinions, supported on the first plate and the second plate, each has a major diameter sized to move between at least two of the legs along a radial path into one of the recesses during installation in the carrier.
