^ The torque converter improves driveability by transmitting the drive force through the use of fluid. However, in certain ranges, a difference in rotation between the pump and the turbine caused by slipping on the fluid, decreases the transmission efficiency of the drive force as well as fuel efficiency.
^ The torque converter clutch mechanism under certain conditions transmits the drive force by automatically connecting the pump impeller with the turbine runner as opposed to using fluid. Therefore it prevents the torque converter from slipping in the manner mentioned above.
