Abstract
A drive assembly for a torque converter includes an axially movable turbine defining a piston of a lockup clutch; and a damper assembly including a first component including a plurality of first ramps and a second component including a plurality of second ramps, the first ramps configured for interacting with the second ramps to generate an axial force on the turbine during a coast condition of the torque converter, the damper assembly being arranged and configured to limit the axial force to prevent the piston from self-locking during the coast condition.
