If your asking for your own gear ratio's, do you have your RPO sticker still? If so, it will be on that. I luckily have all my RPO codes for the car and found my 2.41 ratio on it. Hope I was helpful. 🙂

Sounds like maybe you don't have the car yet? Yeah, 2.41 is by far the most likely I think, but it could have an optional one. Without counting teeth, spinning the driveshaft is the best way to figure it out.

RPO sticker is normally on the inside of the trunk on the trunk or deck lid. Maybe do a search on here for RPO codes and match it to find your gear. But the results are almost all the same.. bad. 2.29, 2.41, 2.56. The best but unlikely would be a special ordered 3.08 which is a pretty ideal compromise gear if you are stuck with a 3 speed transmission.

Compromise being good acceleration but still a nice driver reasonable hwy rpms and decent gas mileage. If you want your cake and eat it to that requires the overdrive.
