Just wondering what kind of gears i have (2.73 or 3.23 i think). The engine's at 2000 rpms when im cruising at 60mph in overdrive (a4). Also, what would the rpms be at when cruising at 60 with 3.73s? 4.10s?

thanks

 

Here is what you need to do, open the driver side door, look for a tag that has alot of codes

GU2 Axle, Rear 2.73 Ratio
GU4 Axle, Rear 3.08 Ratio
GU5 Axle, Rear 3.23 Ratio
GU6 Axle, Rear 3.42 Ratio

find which code matches the odeon the door sticker
