What does the feature "specific manual transmission gear ratios" means for the GS? Does one have a choice of a final rear gear ratio 3.42 vs. say 3.70? I cannot find any info on this and am curious as to what this GS feature is.

It means that they are different compared to the base car for a little extra performance. I don't think you have a choice with the gear set as they are model dependent.

The gearing inside of the transmissions is different regarding the manual/auto versions, so they match up the rear end gears to the respective transmission.

gearing same as base models/ Z51...its different from Z06 & Zr1..just steeper ratios to give our "little" ls3's more grunt...


Application:stdz06 GS/z51 Auto Zr1

First: 2.66 2.97 4.03 2.29
Second: 1.78 2.07 2.36 1.61
Third: 1.30 1.43 1.53 1.21
Fourth: 1.00 1.00 1.15 1.00
Fifth: 0.74 0.71 0.85 0.81
Sixth: 0.50 0.57 0.67 0.67

Final drive ratio: 3.42 3.42 2.56 3.42

hope dat helps

To clarify, the gearing is NOT the same as the base models. It IS the same as the pre-2010 base models equipped with the Z51 option.

It depends what you are asking.
Rear end choices are 2.56, 2.73, and 3.42.
Base auto, GS auto, manual .

Jim, you need to update your chart as there are two transmissions avalible for the ZR1. A "close ratio" and a "wide ratio".

Okay, thanks. It was a combined effort. I'll have to flag down the main contributor to that effort.
