An improvement in both performance and fuel efficiency?

Or just fuel efficiency?

The A10 will not fit the current C7 I was told it mounts to the engine and not rear end.

lgodom

Yes, but the trans axle can changed to accept the A10 components and we know its going to happen. Maybe when more 2017 Z06 info comes out for 2017 we'll have a better idea. I'm crossing my fingers.

Doubtful. The order guide for the 2017 stingray and GrandSport still show 8 Speed Auto as the option.

I have a 2016 A8 and it works and sounds great. I think the 10 speed trans in a Z is not needed.
if you have driven one you know what I mean.

I think the A8 is overkill behind the LT4's torque curve, and the A10 would be a bigger waste. It makes sense behind dual-cam, high feature, turbo V6s to keep them in their power band, but not behind a positive-displacement blown big-displacement engine.

It wouldn't -hurt- anything, and -maybe- it would avoid the gas guzzler tax on the automatic, but I doubt even that.

Remember that more gears doesn't give you more ratio spread. That's totally up to the split between 1st and top gears, regardless of how many are between them. So adding more gears just gives you more shifts along the way, which keeps the engine in a particular RPM range. That's great for motors that are RPM sensitive or only efficient in a narrow band (diesel would be the best example). But we just don't need it.

However, they could introduce it in the 2017 Z06 and then move it into the 2018 Grand Sport and Stingrays.

Gm has put the A10 into the camaro ZL1 for some reason...

Maybe it's just for the ZL1 s gas mileage? For government testing? Or maybe it offers better performances?

Since these cars share the LT4 I ask the question.

MSG C5

GM also confirmed that they will have the A10 in nine of their performance car/truck models across brands, so I would think the Camaro and Corvette would be the two Chevrolet cars with Cadillac and GMC trucks also targeted.

There's benefit in unification (having all cars run the same parts) even if the individual cars don't benefit much from it.

I -am- surprised that if they're building a 10-speed for high-winding V6s and stuff that they make it capable of supporting close to 700ftlbs. I guess they'll go CVT for the small stuff?

JerriVette

Thanks for the heads up ...

Dr. ice

So.......you are saying the ZL1 doesn't need it either? Kinda like a high school basketball game where the fans all know more than the coaches or referees. Hilarious with the amount of armchair experts exist. Makes for good entertainment value though.

Taz Golf

I won't happen until 2018 C7 ! Not production ready yet !

davepl

Correct. The ZL1 torque curve is flat enough that I doubt it achieves any performance benefit from 2 extra gears and even economy is dubious. I honestly couldn't tell you what the rationale is, unless it's unification across the divisions on a transmission capable of supporting both the small blocks and the V6s.

In a -heavier- vehicle like the trucks I can see perhaps a fuel economy benefit from more gears, so it could be that simple - they only want to make one trans, so they make it for the trucks, put it in the ZL1, etc. Remains to be seen if they'll do a rear-mount. I argue they don't need it, but time will tell, not me.

Thanks for the kind words on my input, sometimes I think it's lost on people, so glad to know it's appreciated.

Considering where the transmission is located, I am not sure there is room for a 10 speed transmission?

RonBurgAM

The A10 will eventually be in the Z06 for the same reasons that it is going into the ZL1. Watch any of the videos, the crispness of the shifts are amazing. I believe that the article stated the A10 will be in 8 vehicles by the 2018 MY.

But it won't be for 2017 MY. I spoke with someone in the know that said the Camaro Boss had some sort of deal on this tranny and got exclusivity for a year. He claims it will not be in the 2017 Z06. Sounded convincing to me. Only time will tell.

JerriVette

Whenever the ten speed automatic shows up its fine. I just thought the videos of the ZL1 were pretty impressive. The drivers seemed very impressed with its shift times.

I'm sure the A8 shifts fast as hell too. Maybe there is a running change to improve the A8 too.

Gm s transmission evolution has been quite quick...

I guess the race to improve trucks fuel efficiency in the face of government regulations is a key factor.

The A10 has a 7.39 overall ratio spread, while the 8L90 has a 7.00 overall ratio spread, so in this case, the A10 does have more ratio spread. But I agree that in general having more speeds does not guarantee that.

hawkgfr

Well, the 2 speed power glides and then the a3/4/5/6 owners all said the same thing...we don't need no stinking 8 speed..



I know how the 8 speed drives and ten will just be better...
