The Transmission Control Module (TCM) monitors the friction loss of the torque converter clutch while it is in slipping mode. The TCM calculates friction loss using CAN communication signals such as, engine speed and engine torque, as well as the torque converter turbine speed computed by the TCM. Depending on the friction loss calculated in each program cycle, a corresponding value is added to a factor as long as the torque converter clutch is in slipping mode. The factor is set to 0 when the clutch is opened. If the factor reaches a specified value, a DTC is set.
