Abstract: A method of evaluating a thermal effect of torque converter clutch slip speed calibration settings on a torque converter includes estimating values of a plurality of vehicle operating parameters with a drive simulation model on a computer. The drive simulation model uses drive cycle inputs of a test drive cycle, and a slip speed calibration table to estimate values of the plurality of vehicle operating parameters over a pre-defined period of time for the test drive cycle. The temperature of each of a plurality of discrete regions of the torque converter are estimated with a temperature model on the computer. The temperature model uses the estimated values of the vehicle operating parameters to estimate the temperature of each discrete region of the torque converter at different times during the pre-defined period of time of the test drive cycle.
