OPERATION

See Figure 1


0900c152802600d5.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: VSS with connector and driven gear
The Vehicle Speed Sensor (VSS) is a magnetic pick-up sensor that sends a signal to the Powertrain Control Module (PCM) and the speedometer. The sensor measures the rotation of the output shaft on the transaxle and sends an AC voltage signal to the PCM which determines the corresponding vehicle speed.


TESTING

  1. Disconnect the negative battery cable.
  2. Disengage the wiring harness connector from the VSS.
  3. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190-250 ohms, the sensor is okay.


REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle.
  3. Remove the catalytic converter Y-pipe.
  4. Unplug the VSS electrical connector.
  5. Remove the VSS protective heat shield.
  6. Remove the retaining bolt from the VSS.
  7. Lift the VSS out of the transaxle.
  8. Remove the driven gear retainer and the drive gear.

To install:
  1. Inspect the O-ring on the sensor and replace if necessary.
  2. Install the driven gear and the retainer.
  3. Place the VSS into the transaxle.
  4. Tighten the retaining bolt to 36-53 inch lbs. (4-6 Nm).
  5. Install the VSS protective heat shield.
  6. Attach the VSS electrical connector.
  7. Install the catalytic converter Y-pipe.
  8. Lower the vehicle.
  9. Connect the negative battery cable.
  10. ehichle speed sensor.

2001 sable oil pan


Sounds like he is just going to reseal the pan it is very labor intensive and the price id about right as the exhaust has to be dropped down to access the pan and bolts plus the clean up of the mating services if you get it done demand he install the FELPO OS30717R they fixed the problem with the oem gaskets it cost a little more but well worth the money and no future headaches

My transmision slips and the speedo quits working at the same time in my 1998 mercury sable


Hello wsarah03,

There is a Vehicle Speed Sensor (VSS) mounted on the transaxle, that is a good place to start. The VSS tells the powertrain management system when and how to shift the transmission and also gives the speedometer it's signal.

From your description that the speedometer quit working at the same time I would suspect the a faulty VSS.

Regards,
netvan

Check the transmission fluid first. it sounds like one of the clutch plates is sticking.

If you shift into second after you've stopped, can you get the car moving?
