Abstract
A wet-running multi-disk clutch (B) for a motor vehicle transmission (G) includes a piston (K) provided at a first side of the multi-disk clutch (B), by which a force acting in an axial direction is applicable onto inner and outer clutch disks (IL, AL) in order to engage the multi-disk clutch (B). The multi-disk clutch (B) is supported against an abutting surface (AF) via an end disk (ALE) of the outer clutch disks (AL) at a second side, which is opposite the first side. Grooves (N) are provided at one or both of the abutting surface (AF) and the end disk (ALE). The grooves (N) are configured and arranged such that cooling fluid (O) routed to the multi-disk clutch (B) is flowable out of the multi-disk clutch (B) through the grooves (N).
