Thanks so much for the useful info, this is exactly what I needed. So, does this tell me that the 3.91 gears have more torque in the MM6 transmission or the M10 transmission??? I still can't seem to understand the theory behind the numbers. Like on the MM6 above, for 1st gear, isn't it, for every one turn of the driveshaft, the rear wheels turn 10.42 times?? Or is that backwards???

Both the standard Corvette and the high-performance Z06 use the TR6060 designated as MM6, which is validated to 500 lb-ft of torque, while the TR6060 with the Z51 option features higher ratios and is designated as MZ6. It is validated to 430 lb-ft of torque. The ultra high performance ZR1 uses the TR6060 designated as the MH3, which is validated to 650 lb-ft of torque. The CTSv uses the MG9 version of the TR6060 validated to 560 lb-ft of torque. The Camaro uses the M10 gear set validated to 430 lb-ft of torque

Does this mean that our regular ol' M10 transmissions could start breaking stuff at around 430 ft-lbs. of torque???
