SOURCE: Speedometer - 40MPH

the speedo is electronic, not cable, this problem is caused by a sticking stepper motor that moves the needle, a stepper motor is a miniature electric motor that can move and hold one position, this was a common problem at the dealer I worked at, u will need to pull the speedo and send it out for repair, I use the following link for this service.

REplace fan control module, purchase car repair book on your model and locate it. Common problem, fan could also oscillate in speed at times.

SOURCE: speedometer drops to zero while moving and then

The Vehicle Speed Sensor located on the Transmission is malfunctioning or the connection is malfunctioning.
It is very easily removed and replaced.
The Vehicle Speed Sensor sends vital information for the Transmission to properly Shift. Because yours is malfunctioning, this lack of information is causing shifting problems.
I do not know if you have a Mechanical or Electrical (Gauges or Digital) Instrument Display. I also do not know if you have a 17 or 19 bolt transmission pan, nor what type of transmission you have (AX4N or AX4S) Nor if you have a Speedometer Cable (Mechanical Instrument will have Gauges=Cable).
The best thing to do is to check the connections of the Vehicle Speed Sensor. Unplug and check both sides of the connection for corrosion/oxidation. You can also take this sensor out of the transmission and clean the interior end; reinstall and recheck operation.
If this does not fix the problem, then remove and replace this snsor.
Take the Sensor with you to the auto parts store to compare the part you receive. You should know what tansmission you have and the number of bolts on the transmission pan, and whether you have an Electronic (Digital) Instrument Panel or Mechanical (Gauges) Instrument Panel on your dash.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

It is time for struts (Shock absorbers) or more, have it checked by a suspension specialist, cars get dangerous when they have worn front end parts, not something to mess around with, and your car it at an age,,, Hope this helps, stay safe!
