Exclamation Why no LS3 Auto?

I'd prefer the LS3 rather than an L99, but I don't really want stick... the tap shift is cool, I like that...but I'd like to be in auto sometimes... so cal traffic sucks balls and I had a stick once....

as a DD, stick isn't what I personally want... but I don't care for AFM either... I think it's a hassle to go through a tune to disable AFM as well.

what's the deal?

... because I just don't. I'd prefer the LS3, but I don't want stick. Also AFM imo is a marketing gimick for the most part... I think the gain in MPG is really minor. .. personally that's my thought. Besides, I'm buying a V8 Camaro, I'm not buying this car because I'm worried about MPG to much. I realize that a V8 will never get the mpg that a 4-cylinder does...

3 words...gas guzzler tax. AFM helps enough to avoid it.

it's basically the same motor...get a tune and disable the AFM if you really don't want it.

nope. it really is basically the same motor...with the right tune, the auto can be made fun and the L99 can make up the little HP difference.

Most cost-effective (and rational?) solution seems to be to buy an "LS3" sticker and then go see a hypnotist to plant the idea that you have a ultra-rare COPO LS3/MX0 option...

Is there a difference on models? LS3 or the L99 other than the HP

Sorry if my first post sounds ignorant

welcome to the site.

only big difference is the LS3 is a manual and L99 is an auto...and the rear-end gears are slightly different because of the different gearing in the trans. The auto gets a 3.27, and manual gets 3.45.

If you think AFM is a marketing gimmick, you need to think again and try it out.

AFM out of the box will return 10-15% better MPG in real world conditions.
By virtue of a tune, it can also be cranked up to return even better MPG.

Why is it in the auto?
Automatic transmissions are less fuel efficient than manuals.
It has to do with gear ratios, manuals have that low-geared 6th gear for optimum MPG.
Without AFM, the automatic may have had a gas guzzler tax.... the EPA ratings would've came in around 14 city / 22 hwy (my "guesstimate").

It would not shock me in the least to see a tuned L99-equipped Camaro get 28-29MPG highway... with no other modifications other than a tune.

Is the tune necessary? Absolutely not.
Even out of the box it's rated at 25MPG, which is darn impressive!

Additionally, the operation of AFM is seamless and silent.
You won't even notice it turning on or off.
