Abstract
A torque converter is provided. The torque converter includes a turbine including a turbine shell including a radially extending turbine shell wall, an impeller including an impeller shell including a radially extending impeller shell wall, a diaphragm spring rotationally fixed to one of the turbine and the impeller, and a friction material fixed to the diaphragm spring. The radially extending turbine shell wall and the radially extending impeller shell wall are engageable via the friction material and the diaphragm spring to form a lockup clutch. A method of forming a torque converter is also provided.
