How Do I Tell Which Gears My Z28 Has Out Back?
#2
go look at the code list on the end of the door. get the GUx code (code will be GU then a single digit).
i *think* the following codes mean the following gears (not sure, but i'm sure someone will correct me if i'm wrong):
GU2: 2.something
GU3: 3.23
GU5: 3.42

Thanks, I'll go check right now. Also a good question, which are the more desirable ones to have?

A4's didn't come from the factory with 3.42 gear ratio. Only 2.73 or 3.23. The 3.42 was in the m6.

Ok we were ALL wrong. I just called the local Chevy dealer. I have the 3.23 rear end. The code for that is GU5, the 3.42 gears are actually GU6.
Oh, and the Positrack option is designated by the G80 code. I have that too.
