Abstract
An engine control system for controlling a displacement on demand engine having a plurality of cylinders includes a torque converter with a torque converter clutch. A control module determines a slip speed of said torque converter clutch, estimates a temperature state of said torque converter clutch based on said slip speed, and selectively activates at least one of said cylinders based on said temperature state.
