A method for predicting the temperature of automatic transmission fluid, in real time, in an automatic transmission. The method involves determining a constant for thermal inertia of the transmission, determining a torque converter heat flow, determining a transmission heat flow, determining a transmission cooler heat flow and determining an exterior-of-transmission heat flow. From each of the four above-mentioned heat flows and the above-mentioned constant, the transmission fluid temperature is predicted. The predicted temperature is used to modify operational parameters of the transmission such as its shift tables.
