A control system for monitoring a torque converter in a machine is disclosed. The control system includes a first speed sensor associated with a driving shaft of the torque converter. The first sensor is configured to measure an input speed of the torque converter. The control system further includes a second speed sensor associated with an output shaft of the torque converter. The second sensor is configured to measure an output speed of the torque converter. The control system further includes a processing module adapted to calculate a speed ratio based on the signals received from the first speed sensor and the second speed sensor. The control system further includes an output module adapted to provide indication for a seized condition of a one way clutch in the torque converter based on the speed ratio.
