The temperature of a machine component is controlled by transferring heat generated by a torque converter under restricted conditions to the component. The machine includes a circulating fluid system configured to transfer heat from the torque converter to the remotely positioned machine component. A controller is configured to sense the temperature of the component, and to restrict motion of the torque converter turbine when the sensed temperature is below a desired temperature. Heat generated by the torque converter under the restricted condition is transferred through the circulating fluid system to the remote component, such as the machine power source, to control the temperature thereof.
