Ok, I was just looking at my window sticker for my 2000 Camaro and it says that I had the optional Performance Rear Ratio for $300. What was the ratio for that option for an Automatic Transmission? I am trying to compare it to the one I have now.

 

Your Service Parts label should have "GU5" for the 3.23:1 rear axle. The base, without the performance axle ratio was 2.73:1 (GU2). I think with the 3.23 rear, you also got a "1" for 1st gear on the console shift lever indicator. Otherwise, there was no "1", and the lever was blocked from moving into 1st gear by a plastic tab (which was easily removed).

The performance axle ratio was only available with the 4L60E. All T56 6-speed manuals from 1994-2002 came with the GU6 3.42:1 (GU6) ratio.

Useful 4th Gen info... most of it is correct.

4th Generation (1993 - Present)

 

Thank you very much. I found it when I changed my search words. So I have the same rear end in my 2002 Camaro but it does not have the same get up and go. Back to the fuel filter.

 

Just got my Window sticker from the web and it does reflect what the door sticker says. Says I have a 3.23 posi rear end which is the exact same as my old car had.
