Torque converter having controllable dual clutches

A torque converter, comprising:

• an axis of rotation;
• a cover arranged to receive torque;
• an impeller including an impeller shell non-rotatably connected to the cover;
• a turbine in fluid communication with the impeller and including a turbine shell;
• a first clutch axially displaceable to engage the cover;
• a second clutch axially displaceable to engage the impeller shell;
• and,
• a vibration damper including:
• a first input component non-rotatably connected to a component of the first clutch;
• a second input component non-rotatably connected to a component of the second clutch;
• first and second cover plates, wherein the first or second cover plate includes a radially outermost distal end;
• a seal element fixed to the radially outermost end and sealing the first and second input components against the first or second cover plate;
• and
• an output flange arranged to non-rotatably connect to an input shaft for a transmission,
• wherein for a first lock-up mode, the first and second input components are arranged to transmit torque from the cover to the output flange;
• and,
• wherein:
• the component for the second clutch s the turbine shell;
• or,
• the second clutch includes a piston separate from the turbine shell, and the component for the second clutch is the piston.
