1. A computer-implemented method that, when executed by data processing hardware of a vehicle having a torque converter, causes the data processing hardware to perform operations comprising:
receiving a torque converter temperature associated with the torque converter;
obtaining a torque converter protection schedule including a plurality of torque converter protective action initiation threshold temperatures each having a unique associated torque converter protective action;
determining whether the torque converter temperature exceeds a first torque converter protective action initiation threshold temperature;
when the torque converter temperature exceeds the first torque converter protective action initiation threshold temperature, initiating a first torque converter protective action associated with the exceeded first torque converter protective action initiation threshold temperature;
determining whether the torque converter temperature exceeds a second one of the torque converter protective action initiation threshold temperatures that is greater than the first torque converter protective action initiation threshold temperature; and
when the torque converter temperature exceeds the second one of the torque converter protective action initiation threshold temperatures, requesting a second torque converter protective action different than the first torque converter protective action.
