This truck has an electronic speedometer. There is no speedometer drive cable, and therefore no drive gear to change to adjust the ratio.
You can buy a box for around $170 that is inserted into the sensor circuit to adjust the speedometer readout.
You can figure out how to reprogram the speedometer.
Those are the options I have found. I am dealing with this issue on my girlfriend's son's S-10.
Further research found this reference, which looks good to me. This weekend, I'm going to find the DRAC module and modify it according to the directions.
The electronic module is very specific. Is it worth spending the money just to "calibrate" the speedometer. What are the symptoms of the uncalibrated speedometer. Wheel size change. Tire size change. It would be cheaper and faster to just have a dealer do it then you wouldn't have an expensive piece of useless equipment taking up space
