Abstract
A torque converter includes a bridging clutch having an annular friction liner for engaging axially against a reaction surface of the clutch. The liner is in the form of an annular ring having a friction surface, an outer perimeter and an inner perimeter, with a network of grooves formed in the friction surface to enable a liquid to flow between the liner and the reaction surface. The network of grooves is not open radially in the outer perimeter of the liner.
