Abstract

A shaft (W) for a motor vehicle transmission (G) includes four axial bore holes (B1, B2, B3, B4) for conducting fluid within the shaft (W). A central axis of each of the four bore holes (B1, B2, B3, B4) is spaced apart from an axis of rotation (WA) of the shaft (W). A radial distance (r1) between the central axis of at least two of the four bore holes (B1, B2, B3, B4) and the axis of rotation (WA) differs from a radial distance (r2) between the central axis of one of the remaining bore holes and the axis of rotation (WA). A transmission (G) for a motor vehicle with a shaft (W) is also provided.
