OK, jack up one side of the car and put it in nuetral. Put a chalk mark on the driveshaft (put jackstands under the car before getting under it and put blocks on the front tire that's on the ground so it will not roll!). Now, turn the tire that is in the air, 20 times while counting the number of turns of the driveshaft. Now take the number of turns that the driveshaft had and divide by 10. That will be your gear ratio.

just open your center console and look at the rpo codes

This only works if you assume that the previous owner did not put gears in it.
