MN6 vs M12

NurkVinny · 03-02-2006, 09:48 PM

I am looking for info into which GM cars came with MN6 vs M12 6 speeds. I will reveal the reason for my question after I get a few answers.

I can't find a complete list anywhere on-line.

Thanks in advance.

This is not a comprehensive answer, but I know the 01-04 Corvette Z06 came with the M12 and the 97-04 C5 Coupes and Convertibles came with the MN6. Only difference between them is the gear ratios.

The GTO and all C6's have the M12. The F-Bodies have the MN6. The MN6 was not rated to handle same HP as the M12, in addition to the gear ratio changes. I believe there were difference in the internals, but I'm not sure what.
