    Took a look underneath once again,I wasn't going that route because of too much rust.Was able to get to it from the back of the motor.It took a bit of patience but worth the trouble.Thanks for your help and information,but it can be done if you have the right tools,telescoping mirror,and once again patience.

No , you have to lift the vehicle and Y-pipe to the converter has to be taken off, for VSS replacement.
The VSS removing procedure:-------- 1) Raise /lift the vehicle.Give proper support to the vehicle. 2) Remove dual converter Y-pipe from exhaust system. 3) Disconnect Vehicle speed sensor (VSS) electrical connector. 4) Remove VSS shield from VSS. Remove VSS retaining bolt and VSS from transaxle. 5) Remove retainer clip and speedometer gear from VSS. The VSS is out now. FOR INSTALLATION :------- Follow removal procedure in reverse order. Tighten VSS retaining bolt to 4-6 Nm (36-53 in lb). ----------- For exact location of the VSS sensor.Please click on the link below:---- http://s3.amazonaws.com/2cp-images/question_images/7047/large.gif?1300513396 -------------- Link number 2:---- http://s3.amazonaws.com/2cp-images/question_images/7046/large.gif?1300513396 -------------- The VSS - Located - Rear center of engine compartment - mounted on transaxle. The transaxle is located on the driver side. if you look down under the air intake tube tou will see it or look for your Transmission Fluid Dipstick and look down there and there the VSS is located. ---------------- The converters on a V6 is part is the Y-pipe, so remove the pipe and the clamp at the extension pipe, be careful with the flex part! Too much flexing and it will break.---------- This should help.Keep updated.Thanks.Helpmech.

For 1998 Mercury Sable 3.0L EFI 6cyl the Vehicle Speed Sensor is located mounted on transmission.

There are 2 VSS - One is called a Turbine Shaft Speed Sensor - Located - Left rear lower side of engine compartment, on rear side of transaxle. The is the VSS - Located - Rear center of engine compartment - mounted on transaxle. The transaxle is located on the driver side. if you look down under the air intake tube tou will see it or look for your Transmission Fluid Dipstick and look down there.

I have found that if you buy and look at the part you will find it...

    P0500 - Vehicle Speed Sensor Malfunction

    Basically this means that the vehicle's speed as read by the Vehicle Speed Sensor (VSS) is not working properly.

    Symptoms of a P0500 DTC may include:
    * loss of anti-lock brakes
    * the "anti-lock" or "brake" warning lamps on the dash may be lit
    * the speedometer or odometer may not work properly (or at all)
    * your vehicle's RPM limiter may be decreased
    * the shifting of an automatic transmission may become erratic
    * other symptoms may also be present

    Causes: A code P0500 may mean that one or more of the following has happened:

    * The Vehicle Speed Sensor (VSS) is not reading (functioning) properly
    * There is a broken/frayed wire leading to the vehicle speed sensor
    * The vehicle's PCM is not correctly configured for the actual tire size on the vehicle

    Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.

    Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly.

    If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure wil depend on your make and model of vehicle.

    If everything looks OK, replace the sensor.

    Good luck.

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.

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.

netvan

I'm trying to locate the 02 sensor up and down stream on my 1998 mercury 3.0 dohc could i please have a picture or diagram.


You will, in all probability have to get under the car to see it-you have one in front of the catalytic converter (each side) and one behind the cat (it doesn't really affect how the car runs, it only monitors the car efficency)-the O2 sensors are perpendicular to the exhaust pipe and have a 4-wire harness connected to it. they look like this:

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?
