ABSTRACT OF THE DISCLOSURE A clutch drum for an automatic transmission features a large diameter portion in which a plurality of first slots define castle-like projections or crenelations about one end thereon and a second set of slots which originate in the projections near the tops thereof and which extend to and terminate in an essentially frustro- conical portion which interconnects the large diameter portion and a small diameter portion containing a piston therein. The first slots serve to mount clutch discs within the drum while the second ones mount discs about the drum. The relatively wide castle-like projections allow the production of the drum from relatively light gauge sheet metal, which has adequate structural rigidity and a reduced maximum diameter. -12-
