Abstract
A shaft (W) for a motor vehicle transmission (G) may have axial bore holes positioned within the shaft and configured to guide fluid within the shaft. The shaft may have first, second, and third axial sections (W, W, W), the second axial section being axially between the first and third axial sections. Fluid enters the axial bore holes in the second axial section and exits the axial bore holes in the first and third axial sections. One of the axial bore holes (B; B, B) is arranged, at least partially, in the first axial section and is radially spaced from an axis of rotation (WA) of the shaft. Another of the axial bore holes (BRS; B_SE, B) is arranged, at least partially, in the third axial section. The one of the axial bore holes (B; B, B) is coaxial with the other of the axial bore holes (BRS; B_SE, B).
