Abstract
In a clutch for an automatic transmission having a unilateral clutch disc construction in which outwardly toothed plates are interleaved with inwardly toothed plates, and the plates have friction faces only on one side, the inner peripheries of the outwardly toothed plates and the outer peripheries of the inwardly toothed plates have circumferentially spaced notches. These notches prevent distortion due to thermal expansion occurring when the clutch discs are unevenly engaged.
