ABSTRACT:
An engagement structure for coupling a connecting shell to a clutch drum of an automatic transmission includes protrusions on the connecting shell that engage with grooves of the clutch drum. Edges of the grooves and edges of the protrusions are rendered by plastic deformation upon press-stamping to be formed thicker than other portions of the connecting shell and clutch drum. The resulting increased area of abutment between the connecting shell and the clutch drum transmits the same torque with less surface pressure, such that reduction in weight and size of the overall transmission components can be realized.
