A torque converter includes an impeller and a cover rotationally fixed to the impeller. The cover has opposing inner and outer surfaces and a through hole extending from the inner surface to the outer surface. A stud is attached to the cover. The stud has a head and a shank extending from the head. The head defines an annular projection circumscribing the shank and raised from the head. The stud is disposed on the cover with the shank extending through the hole to project from the outer surface and with the head being connected to the cover by coalescence between the annular projection and the inner surface creating a hermetic seal around the hole.

A torque converter includes a cover, an impeller including an impeller engagement section, an axially movable turbine piston including a turbine engagement section configured for engaging the impeller engagement section to form a lockup clutch and a coast engagement structure configured for contacting the cover to limit axial movement of the turbine piston away from the impeller in a coast condition.
