Abstract
A torque converter comprising a front cover, an impeller having an impeller shell connected to the front cover, a turbine having a turbine shell and at least one blade attached thereto, and a lock-up clutch configured to selectively couple the turbine shell to the impeller shell for torque transmission therebetween is provided. In embodiments, the lock-up clutch comprises a clutch plate connected to the turbine shell and extending radially outward therefrom. The clutch plate may include a first end, a second end, and a slot defined between the first and the second ends. The lock-up clutch further may include a piston connected to the front cover, and a piston actuation plate connected to the piston, wherein the piston is configured to actuate the piston actuation plate to close the lock-up clutch to connect the turbine shell to the impeller shell.
