ABSTRACT:
A torque converter has an end cover or input shell which is stamped from a sheet metal plate and has a stiffening fluid portion and an outer flow formed annular rim. The impeller, turbine and stator are assembled along with a torque converter clutch after which the rim portion of the end cover is welded to the impeller. The impeller and the cover have a flange or radially extending portion that is selectively trimmed to control the dynamic balance of the assembly. The turbine member is cast with the outer core and blade portions integral and an inner core member is welded thereto. This is completed prior to assembly within the torque converter.
