Default ‘18 A8 rear gears

Found a ‘18 SS I’m thinking about buying. Dealer sent me the spec sheet & it says it has 2.77 gears.

i looked up the A8 ratios & it first few gears are pretty deep. I asked the dealer if that was a common ratio & they told me it was.

Just seems high, so wondering wha gears A8 owners usually get?

There are no other gear options...A8 get 2.77's and the M6 gets 3.73's. The gearing on the auto is actually far better then the M6 due to the trans ratios.

Thanks. Upon more looking that is what I concluded.

BTW, I bought it last night. So stoked!

Started researching stuff to do to it before I bought it, LOL, so I sure will.

Thanks!

I’ll actually be in South Bend in the end of Sept.

Welcome. If you aren't experiencing the A8 shudder, get ready to. If you already are, most guys are experiencing a nightmare at the dealerships.

Mine is actually at the dealer right now for the flush. Once I get it back I will just do a new converter and tune myself, I just wanted the new fluid in it.

They are going to make aftermarket 3.27 gears for those rear ends. Motive and yukon has plans and 4:10s for the M6 guys. PRI is coming up
