if you can feel the AFM kicking in and out on the highway...AFM = Active Fuel Management feature

Background: Both the manual and the auto have AFM, this kills 4 cylinders of the V8 when the car does not need it, mostly up at cruise on a flat surface at interstate speed when it's "coasting". But the manual only uses this feature in the ECO mode, which most people are not using with this car.

But with the auto trans, no matter what driving mode you choose, it is on, unless you are using paddles which again, most people are not using.

The problem on other Chevy cars (like the 6.2 Camaro I own) is the shift in and out of 4/8 mode in very apparent and there is a tug on the car every 30 secs at highway speed. Once you know what it is, it's like the mattress and the pea, you can't forget it.

So far, reports are that the auto Trans C7 software makes it far harder to tell when it kicks in/out...which is GREAT news....

If you have a auto trans, can you tell us what you think?

While I haven't yet received my LMG/2LT - I do have a automatic transmission related question for you all: I've heard many times that the C7 only shares two parts with the C6, but I was just reading this month's Corvette magazine and the C7 feature mentions that the C7's six-speed auto is "the same as the C6." Not that is matters - -my C6 automatic has behaved very well for all these years, but I'm just wondering if anyone out there know's the correct story.

That is odd. I also was under the impression that there were only two carry over parts. I thought I remembered a video where Tadge Juechter talks about the new six speed tranny? Maybe I am wrong about this, but that is what I thought.

 

[glen e]

I took it as a carryover, but with new software for the driving modes...

The C7 uses the venerable 6L80 trans but the calibrations and possibly the gear ratios are new.

In the December, 2013 issue of Vette magazine, there is a detailed technical article on the StingRay's automatic transmission. As noted above, it talks about many software changes. The article describes the following changes from the previous generation auto trans, including its lighter weight, its being shorter, its different torque converter (resulting in a 31% reduction in both primary and secondary inertia), it's significantly shorter time on full throttle shifts (it is faster 0-to-60 than the manual trans), its ability to get much closer to the redline before requiring a shift, and much more. This trans may bear the same 6L80 name as the C6's auto, but this is a much changed unit.

Good to hear. Things only get better, knock on wood. Did you mean Dec 2012 issue?

Thanks for the additional info. Can't wait to get mine- soon!

No doubt but it's still a slush box

Just kidding, it sounds much improved but honestly, the C6 auto really wasn't that bad.

Personally I'm a row your own gear kind of guy but have had the opportunity to drive dual clutch auto/manuals at full chat and absolutely love them. For me, in a sports car, it's either a dual clutch or a stick but the GM and Mercedes slush boxes are pretty darn good these days.

I wondered when I posted originally if I should have added, "it really says December, 2013 on the front cover," but did not, and yes, it really is a December, 2013 issue, just like the latest version of 'Vette magazine also says "December, 2013" on its cover.

I can't tell at all... this vehicle is INCREDIBLE... in every way. I've used the paddle shifters, have driven the car in Weather, Economy, Touring, Sport and Track, have hit it at different speeds (up to 130 today) and NEVER noticed the transition.

Oh cool. I gotta get with the vette mags and such. Maybe it's a quarterly magazine?

Thanks for the update. You managed 130 mph at less than 4000 rpm or have you already finished the break-in miles?

 

[jakesvette]

I would like to know about the paddle shifters. Somewhere on this forum I heard that right hand side was upshift and left was downshift. On my 2007 upshift was on the front of the wheel about the spoke and downshift was the paddle behind the wheel. It was the same for either side. Anybody received a car yet that can let me know?

 

[Micrider]

That is correct right side is up shift and left is downshift. Both paddles are behind the wheel.
