| 5 speed auto vs 6 speed auto 2006, 2007 Hi all-I need some advise.. I am looking to pick up a certifited used STS v8 and I am confused about which one to look at the 2006 or the 2007. I see the only real difference between the two is the transmission. Was there something not good about the 5 speed and thats why it was only in the 05 & 06 models? Does anyone have an opinon on the transmisson? thanks |
