ABSTRACT:
A lockup clutch assembly and fabrication method for a hydrokinetic torque converter having a clutch assembly located within the cover of the torque converter. The clutch assembly comprises a first friction disc drivably connected to the torque input member of a multiple ratio geared transmission and a second friction disc connected to the torque converter cover. The driving connection between the clutch and the cover is achieved by interlocking spline teeth which permit torque transfer through the clutch assembly while accommodating relative axial displacement therebetween. The cover includes a radial wall and a cold formed peripheral portion extending generally axially from said radial wall. The peripheral portion of the cover as formed has a surface with a substantially smooth circumference at an end distal from said radial wall.
