The torque converter clutch solves this by locking the turbine on the converter’s housing, thus creating a direct, slip-free of charge connection amongst the engine and transmission. This “lock-up” substantially enhances gasoline performance and decreases the transmission’s running temperature. A torque converter are not able to attain 100% coupling effectiveness. https://torque-converter-clutch75296.thelateblog.com/34484052/an-unbiased-view-of-torque-converter-clutch
