Abstract
A method of adapting a pressurized fluid supply to a torque converter clutch is provided. The method includes: learning a first pressure point related to an average of ramp pressure and an average of engine torque over a first time period; learning a second pressure point related to a second average of ramp pressure and a second average of engine torque over a second time period; determining a plurality of adapt values based on at least one of an extrapolation and an interpolation between the first pressure point and the second pressure point; and adapting the pressurized fluid to the torque converter clutch based on the plurality of adapt values.
