Re: Speedo drive gear

You could also have a good speedo repair shop have a got at it and get both the odometer 
and speedometer back in calibration:

I had a calibration gear box built for my 4x4 many years ago and that shop just got it so 
the speedo was back in spec, the odo reading was whatever it was.

>>> OK, I finally have a working speedometer in my Jetta again.  Now, I would really like to fine tune the speedo as it is just a bit off according to the GPS.  It measures about 4 mph fast and the odometer is high by about .16 miles.  So…..I currently have the red speedo drive gear  in my ACH transmission because that is “the one you are supposed to use”.  Would changing to the white drive gear speed up my measurement or slow it down?  Obviously I need to slow the thing down a bit.   So what say the gurus?  Hayden
