Abstract: A transmission gear unit includes a carrier including a first disc formed with a first chamfer, and a second disc, a one-way clutch including a first ring contacting the second disc, and a second ring, located radially outboard of and surrounding the first ring, and formed with a second chamfer, and pinion shafts, each shaft supported on the first disc and first ring, engaging the first and second chamfers and supporting a pinion thereon.

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.

Abstract: A planetary gear unit for an automatic transmission includes a pinion carrier including a first disc formed with first holes located radially from an axis joined to a second disc spaced axially from the first disc and formed with second holes, each second hole being aligned with a first hole, a clutch ring contacting the second disc and pinion shafts, each pinion shaft extending axially through one of the first holes and one of the second holes and supporting a pinion thereon.

Abstract: A planetary gear set includes a sun gear including a first set of gear teeth having a helix angle and second set of gear teeth formed as a single unit with the first set of gear teeth and having a second helix angle of opposite hand relative to the first helix angle. A ring gear includes a third set of gear teeth having a third helix angle, and fourth set of gear teeth and having a fourth helix angle of opposite hand relative to the third helix angle. Planet pinions, each include a fifth set of gear teeth having a fifth helix angle, and sixth set of gear teeth formed as a single unit with the fifth set of gear teeth and having a sixth helix angle of opposite hand relative to the fifth helix angle.
