Abstract
A torque converter clutch slip rate monitoring system includes a slip rate calculation module that receives a raw slip speed of a torque converter clutch and that calculates torque converter clutch slip acceleration based on the raw slip speed. A torque converter clutch slip rate monitoring module detects deviation of the slip acceleration from a predetermined range during a pulldown of the torque converter clutch.
