Which transmission came in the 06 SS? 4t65-e-HD, yes but I am seeing so many different RPO codes. I think the 06 SS was MN7 version?

I am mainly interested in knowing the final drive ratio on the stock transmission. Does anyone know? I am seeing so many different things online and cannot confirm.

Also, was the transmission that came in the Pontiac GXP Comp G package a different final drive ratio than the 06 MC SS? If so that could be why I am seeing so much varying information.

Somebody here on this forum has got to know the answer.
