You can go to the parts department at the dealer with your vin# and that can give you the PRO codes and write up to your Sierra's optional ordered. There is also in your glove box is your PRO code sticker, and you can look up what gear ratio is in your Sierra.

hardhitting12, if you would be willing to do so you can direct message me your VIN I would be able to look up the gears that are in your truck. I hope to hear from you soon.
