Not sure what's happening, but my speedometer is about 5 mpg slow or more going over 20 mph. It was changed from auto to a 3 speed by another person... but it also has 195/70/15 on the back. Or is that my problem?
Oh dang! So I'll have to open up the transmission and diff to figure that out right?you need to match the speedo gear in transmission to the rear axle ratio and tire height.
