摘要： An engageable coupling assembly having reduced spin losses and method of assembling such assembly within an automotive transmission to reduce such losses are provided. The assembly is adapted for use with pressurized fluid. The assembly includes first and second coupling members that are supported with respect to each other for relative rotation about a common rotational axis. The coupling members have a first pair of annular faces that oppose each other and define an annular space therebetween. A first face of the first pair has a set of pockets spaced about the rotational axis. A second face of the first pair has a set of locking formations. The coupling members have a second pair of annular faces that oppose each other. A first face of the second pair defines a first set of fluid grooves fluidly communicating the annular space with an exterior surface of the assembly. The fluid grooves are configured to conduct the pressurized fluid from the annular space and out of the assembly in an axial direction during an overrun condition of the assembly, thereby reducing spin losses when the assembly is disengaged.
