If it's stock, you can check the glove box for the codes. GU2= 2.73:1 GU5= 3.23:1. Also if you have a selectable 1st gear on the console you have 3.23.

What do you mean a selectable 1st gear??? Like OD, D and 1 and 2 on the shift console??? Cause i know that i have 2.73s just by how the rpm's are when i drive.
