Answer
Omar,
You may need to have your transmission flushed and filled with clean fluid and have your transmission filter replaced.  An erratic speedometer needle may be an indication of a bad speedometer unit.  The gears may have worn down; causing it to bounce around.  When you get your fluid and filter replaced, have your mechanic inspect and replace the speedometer cable if necessary.
Good luck!
