Two speed sensors, one I replaced behind transmission and axle, but second sensor is for speedometer cable VSS. I can't locate that one. I have the part picture I sent you. Where is it located and can you show me diagram?

Welcome to 2CarPros.

The VSS is located at the rear of the engine/trans-axle. See the attached picture and let me know if that helps. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hi:
The input speed sensor on this vehicle is located internally. You will need to remove the pan. In all honesty, if I recall correctly, the transmission needs to be removed.

If you look at pic 3in, it shows the location of the sensor.

Here are the directions for removal. The attached pic correlates with the directions.

Important:
The tab on the sensor housing (46) fits into the recess on the case boss.
For drive sprockets with 35 teeth, use a black sensor housing. For drive sprockets with 32 or 33 teeth, use a natural colored sensor housing.
