Question about 2001 Pontiac Grand Prix
It says gear ratio is incorrect, but it is the original motor. Any suggestions?
Have you changed tires and wheels to a different size? If so, that will cause a code to come up. The gear ratio is set as a value in your computer. If you change tire sizes that will cause this problem. You can have this recalibrated at your Pontiac dealer. Good luck! Phil
