Hello I will help you with your question,

Does it seem to shift normally> (It should)

If it shifts normally there is no problem driving it until you can get the speed sensor repaired,

Let me know what I can do to help you

Thank you

I am sorry, you have a cable drive not a sensor on this vehicle so it is unlikely that the cable has broken unless you hear a noise form the back of the speedometer. It will be likely that the speedometer head will have to be replaced with a used unit.

This should be less than $250 but that depends on where a used unit can be sourced from.

The newer vehicles use a speed sensor to communicate the transmission speed to the speedometer head and this sensor often fails but yours uses a cable.

If you do hear a noise like a broken cable turning then it is a simple matter to pull the cable and install a new one which would be less than $100 if that were the case.

Sorry for the misinformation in my first post, please let me know what I can do to help you

Thank you
