It reads the transmission output shaft speed and sends that data to the electronic control module (ECM) to regulate shift timing, hydraulic pressure, and driveline function. You typically replace this sensor when the transmission displays erratic shifting, logs a speed sensor circuit fault code, or when the sensor is physically damaged or leaking.
