speedo problem

["John Di Fede"<difejo@consumer.org>]

     David, there is another gear on the output shaft of the overdrive.  
     This gear rotates with the output shaft and turns the speedo drive 
     gear which connects to the speedo cable. 
     
     It wears out over time.  The only way to change it is during a 
     transmission overhall
     
     
     John.
