Abstract
A torque converter comprising a cover arranged to receive torque, an impeller having an impeller shell non-rotatably connected to the cover, and a turbine in fluid communication with the impeller and including a turbine shell is provided. In embodiments, the torque converter includes a lock-up clutch including a piston plate, an output hub connected to the turbine shell and arranged to non-rotatably connect to a transmission input shaft, and a seal plate disposed, at least partially, axially between the piston plate and the turbine shell. A connector is arranged to connect the cover, the piston plate and the seal plate to each other, wherein a first chamber is formed at least in part by the piston plate and the seal plate and a second chamber is formed at least in part by the cover, the seal plate, and the piston plate.
