Torque converter having multiple flow passages

A torque converter, comprising:

• a front cover arranged to receive a torque;
• an impeller assembly having an impeller shell non-rotatably connected to the front cover;
• a turbine assembly in fluid communication with the impeller assembly and including a turbine shell;
• a lock-up clutch including a piston and a seal plate disposed axially between the piston and the turbine shell;
• a backing plate non-rotatably connected to the seal plate and sealed to the piston;
• a flow plate disposed axially between the backing plate and the front cover, the flow plate being non-rotatably connected to the backing plate and the front cover;
• and
• a through-bore extending axially through the backing plate and the flow plate, wherein a first chamber is bounded at least in part by the piston, the seal plate, and the backing plate, and a second chamber is bounded at least in part by the front cover, the piston, the backing plate, and the flow plate.
