A torque converter assembly comprises: a cover for driving engagement with a prime mover; a piston plate including an annular surface for engaging a clutch; and, a sealing plate comprising a substantially radial wall arranged between the cover and the piston plate and disposed radially inward of the annular surface, wherein: in a lockup mode for the torque converter, the sealing plate blocks fluid flow between the cover and the piston plate; and, in a release mode for the torque converter, the sealing plate is deflectable to enable a fluid flow between the cover and the piston plate via a pathway between the cover and the sealing plate.
