F150 Again

Speedometer does not need to be adjusted for gear change. Needs to be changed for tire size change.
Incorrect. The speedometer sensor is in the transmission, and is counting transmission revolutions, then doing a calculation based on tire size and final gear ratio.
If you change the final gear ratio, you need to change the calculation that the computer does to determine speed.
