A component surrounding an axis for directing fluid along a flow path in a transmission for a motor vehicle. The component includes a first wall having a thickness formed with an inner surface facing the axis, and a hole spaced about the axis and extending through the thickness of the wall, and a channel formed in the wall, communicating with the hole and the inner surface, including a base having a length that extends angularly about the axis, and having a depth that increases along the length as distance from the hole decreases.

What is claimed is: 1. A ring for a one-way clutch, comprising: a wall including an inner surface facing an axis, an outer surface formed with cam surfaces, and radial holes extending through the wall to the cam surfaces; and channels formed in the wall, each channel having a length that extends angularly about the axis, a depth that increases along the length as distance from one of the holes decreases, and including a base that is open to the axis along the entire length of the channel, an axial surface extending from the base toward the axis and along the entire length, and a terminal surface extending from the base and the axial surface and located at an end of the length at the one of the holes. 2. The ring of claim 1, wherein the base is located to block fluid thrown radially outward as the ring rotates. 3. The ring of claim 1, wherein the depth of the channel is a maximum at the hole. 4. The ring of claim 1, wherein the length of the channel extends on opposite angular sides of the hole, and the depth of the channel is a maximum at the hole. 5. The ring of claim 1 wherein the ring is supported for rotation about the axis. 6. A ring for a one-way clutch, comprising: a wall including an inner surface facing an axis, an outer surface formed with cam surfaces, and radial holes extending through the wall to the cam surfaces; and channels formed in the wall, each channel having a length comprising first and second lengths that extend angularly about the axis on opposite angular sides of one of the holes, a depth that increases along the first and second lengths as distance from the one of the holes decreases, and including a base that is open to the axis along the entire first and second lengths, and an axial surface extending from the base toward the axis and along the entire first and second lengths. 7. The ring of claim 6, wherein the base is located to block fluid thrown radially outward as the ring rotates. 8. The ring of claim 6, wherein the outer surface formed with spline teeth. 9. The ring of claim 6, wherein the depth of each channel is a maximum at the hole. 10. The ring of claim 6 wherein the ring is supported for rotation about the axis. 11. A hub comprising: a wall including an inner surface facing an axis, an outer surface formed with cam surfaces, spline teeth, and radial holes extending through the wall to the spline teeth and cam surfaces; and channels formed in the wall and extending along an entire length of the inner surface, each channel having a length that extends angularly about the axis, a depth that increases along the length as distance from one of the holes decreases, and including a base that is open to the axis along the entire length of the channel for blocking fluid thrown radially outward as the ring rotates, and an axial surface extending from the base toward the axis and along the entire length. 12. The hub of claim 11 wherein: each channel further comprises a terminal surface extending from the base and the axial surface and located at an end of the length at the one of the holes. 13. The hub of claim 11 wherein the length of the channel extends on opposite angular sides of the hole, and the depth of the channel is a maximum at the hole. 14. The hub of claim 11 wherein: each channel has a length further comprising first and second lengths that extend angularly about the axis on opposite angular sides of the one of the holes; the depth increases along the first and second lengths as distance from the one of the holes decreases; the base is open to the axis along the entire first and second lengths; and the axial surface extends from the base toward the axis along the entire first and second lengths.
