Abstract

A torque converter, including: a cover; a first through bore for receiving a transmission input shaft; a clutch including a piston plate; a plurality of fasteners connected to the cover; and a plate connected to the cover. The plate includes a radially aligned wall including a plurality of openings in which the plurality of fasteners is disposed; a second through bore at least partially aligned, in an axial direction, with the first through bore; and a plurality fins extending from the radially aligned wall in the axial direction. Each fin includes a first end aligned with the first and second through bores in the axial direction. Each fin includes a second end disposed radially within the plurality of openings. A space, aligned with an axis of rotation for the torque converter and the second through bore, is formed between the respective first ends.
