Abstract
A transmission includes a torque converter with an impeller, a turbine, a torque converter clutch, a hydraulic torque converter clutch control circuit and a controller that commands a first pressure into the hydraulic torque converter clutch control circuit during a transition period between a torque converter clutch OFF mode to a torque converter clutch ON mode and prior to the torque converter clutch reaching capacity and a second pressure into the hydraulic torque converter clutch control circuit after the torque converter clutch reaches capacity.
