.....A10.....A8

.....0.69.....
.....0.64.....0.65

Yes, that added gear may help on the top end a smidge, which is where I think it'll help add .05-.10sec / 0.5-1mph on the top end. But as for basic acceleration 0-100 or so, the difference in gearing is the same as going from 2.77 rear gears to ~2.85 = zero difference in the real world.

Nah, I just pasted part of it for the wording. Better than having to re-type it. As for the rest, it's going to help a lot more than you realize. If there was only that smidge of an improvement, GM wouldn't have even bothered to consider doing this for the Camaro. They also wouldn't have done it just for a minor 1/2 mile per gallon pick up.

They put a completely brand new, untested A10 in their halo muscle car for a reason. It works, and it works well. We've seen the results in the new GT's as well. The transmission produces results, is pretty stout from a reliability standpoint (thus far), and is good on fuel economy to boot.

The real truth is that extra gear will continue to help the Camaro charging down the strip where the previous one was starting to shut down. There's legitimately not much difference between a current Camaro and a current GT. They're roughly the same dimensions, the Camaro is a hair lighter, the GT a hair more power (roughly 10-15hp).

I fully expect to see a much more 11.9-12.0 run from the Camaro with this new transmission. Why? Because if you can knock off a tenth at launch and perhaps a .1-.2 down the track, the car could easily do that. We've already seen many repeatable low 12.1-12.2 out of the Camaro with the A8. And I really hope we see them running it cooler weather to boot, only because that's what the Mustangs did.

It's hilarious you say that. The A8 made zero gains over the A6 when it came to straight line acceleration when they changed over for the C7, but did make mpg improvements from 16/28 to 16/29. And that with the A8 having a significant improvement in gearing over the A6.

The LT1 makes pretty good torque to where gearing improvements are less important. A tenth from launch improvement will absolutely not happen.

It most certainly made the cars faster

Are you really saying that because of the hero time in a corvette forum that’s on a different track and different day to the others?


The times as a whole got faster. If it’s the same dude I’m thinking with a hero a6 then lol. Do you really think they can run 11.3 bone stock? That time is BS. People that track these cars in real life think the a8 corvettes are faster than the a6.

Even accepting the time the argument is flawed. The a10 is not the a8. And you continue to only consider gearing when other changes besides that can also make the a10 car faster. You may well be right I don’t care much I’m keeping my 16. Just think you are being a bit too hopeful against the ss lol

I expect the A10 to show some slight improvement, but it's not going to be like a GT going from the A6 to A10 difference. That engine really needs the gearing to stay up in it's power. I believe the biggest reason for the A10 replacing the A8 is the simple fact that Gm will be able to hit the required EPA regs withought the shitty afm and crap converter slipping tune that caused a bunch of Converter failure. The 8l90 is solid transmission overall and adding another gear before 1:1 is not going to make a huge difference on a engine with a flat torque curve from 2-5400rpm.

[Snowblind]

On a street tire the gains from the A8 to the A10 will only be realized with an experienced driver, I would guess .1 with the stockers at the track.

I think where the A10 will shine is with a DR and someone who can drive. I agree with Ultraz earlier comment, if GM institutes a Drag Mode of some sorts like Ford has done then the gains will be greater....although I wouldn't get my hopes up on that, it would he nice to see the "track" setting be more agressive and give you firm, positive shifts.

The slightly steeper 1st gear, the extra gear between 4th and 5th to help stay in peak power/shift recovery, and the added shift firmness we have seen on the A10 GT's should give you a solid .2+ on DR's in the 1/4 imo. 11.79 in negative DA and excellent prep is possible with no other mods done.

[torqueaddict]

TC efficiency / design and how the shift points are programmed could also contribute to better performance for the A10. I didn't think it would make that much of a difference as well, but I'm not so sure now. I'd guess the gains would be small, but noticeable.

[KingLT1]

True stock for stock...I was thinking more a long the lines of the A8 with a good tune vs the stock A10 because it appears the A10 is dialed in out of the gate. The A8 leaves a ton on the table in stock form. It's a shame really because the transmission kicks ass once it's dialed in. GM really shit on it with the stock tuning.

And yes my next go around I'll change cam on a LT1 without dropping the pan, putting it into just as easy as a LS1, which was candy.

This I have to disagree with. OHC engines are easier to do a cam swap on. I did cam swaps on my GT with hand tools. The only difficult part was lining up the chains properly and that was more just being careful and counting the links and making sure they were where they were supposed to be. Nothing was more satisfying than that first startup. The difference is that with an OHC engine you just pull the front cover and valve covers and the cams come out the top and go in the top. With OHV engines you have to remove everything from in front of the engine and even then some people find it easier to just pull the whole engine out of the car or even take the bumper off. After looking at the details surrounding a 5th Gen Camaro cam swap I decided against it. Other than that I agree with your comments.

Not sure all the bugs are out of the A10 yet .. Mustang owners that have added power are having slippage problems in the upper gears .. Tuning the trans has not been totally figured out ( at least for the Mustang ) A few stock Mustangs with the A10 have lost all the gears but for first and rev .. Myself I would wait for the next model year so they have all the bugs worked out , at least for the Mustang .. The Chevy A10 might not have these problems or have worked them out with better tuning ?

Pretty much my thought process on the whole thing. The other aspect to factor in here is that most car mags never bothered to really re-test the Camaro since it came out in the 1/4 mile (for the A8 at least). So, no one really tried hard to get it sub 12...or even 12.0-12.1

Adding this new transmission guarantees we will see someone going max effort...

It's not that I'm hopeful against the SS, it does fine with the A8. I just don't think the A10 is a magic bullet that will help much, just .1 at most.

I think more noticeable gains will be made on everything else other than just straight line acceleration (autocross, roadrace, mpg, every day comfort, etc.).

And I likewise don't think it is a magic bullet either. However, I think with all the attention the A10 has received in the GT, the Camaro will equally see very similar attention paid to it. This is why I expect the times I've repeatedly said.

So, expect max efforts being made to rip off a sub 12 time...

We all want that dopamine hit inside our brain. Lol.

The Camaro SS has proven itself to be quicker than the mag times regardless of what the naysayers think. If the A8 brought sub 12s, no reason the A10 wouldn't.

For the mags though, Chevy needs to take a page from Ford's playbook and hire an Evan Smith equivalent. A track should be prepped and a day chosen with the perfect weather conditions. He / she should spend all day getting used to the car's habits. Oh, and they should play around with the tire pressure and who knows what else.

11's guaranteed. They can then sell the published info to other mags so it becomes 'official'.
