Output Shaft Speed Sensor
WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Output shaft speed sensor may also be referred to as transmission shaft speed sensor or shaft speed sensor.
Output shaft speed sensor is located on the case of overdrive unit attached to rear of transmission. See Fig 1 . Output shaft speed sensor is located above the lugs on the park gear in the overdrive unit. Speed sensor input signals are generated when lugs on the park gear rotate past the face of sensor. Input signals are delivered to TCM. The TCM uses this input signal for controlling transmission operation. The Vehicle Speed Sensor (VSS) also serves as a back-up to the transmission shaft speed sensor. The VSS signal is also shared with the Powertrain Control Module (PCM).
