The Speedometer shows 15 Km to much. Are there any adjustment to do? Or do i need to change Gears in the Transmission. Thanks Goran
What size tires are on it? What size does the door sticker (or other info) say it was built with? How do you know you have an error? Patrick
My Daughter test it with the Phone. Is an App with a Speedometer in. I will see what the book say. Thanks Goran
So the error isn’t from the tire diameter then. Sounds like either the sensor on the transmission is bad or the speedometer (via the PCM) needs to be recalibrated (possibly it was changed for non stock (taller) tires and not changed back?). Here’s another forum’s discussion of the set up. http://67-72chevytrucks.com/vboard/showthread.php?t=651002 Patrick
Iwill take a look on that one. Maybe best is to buy a Bicycle Computer, and put beside the Speedometer. Thank you. Goran
