I understand the need to meet CAFE regs driving placement of the A10 in higher volume vehicles. However, just a thought here, has GM consciously decided to hold off on placing it in the Corvette until they get some reliability information? Is it possible that due to the A8 issues, they want the A10 to be bullet-proof before they put it in their premier sports car?

 

I think it's about 90% the same hardware. The differences are in SW and in how the valvebody is actuated (might be same HW, as I'm not sure how the HW/SW layer works).

Transmissions are super similar though.

 

Thinking about moving from a 2015 to a 2018 to put the A8 in the rear view mirror. Had minor cold start shift bump issue but it went away on it's on. Don't want to see GM rush through a 10 speed and not get all the bugs out for 2018. Also, don't want to spend another 75K and have issues with a new auto trans all over again.

 

^^^ Since there is no guarantee on whether the A10 will fit and make it's way into the C7, I'm not sure if we will know anything until the Bash in April. The ZR1 or Z06X camo mule is supposed to make it's debut at the Detroit Auto Show later this month, so hopefully we will know more. If the C7 does get the A10, it may be limited to the top line model (ZR1?) similar to the Camaro ZL1. Depending on the timeline of the C8, GM may wait to change the Corvette automatic transmission (again) considering it would be the third automatic tranny during a 5 year (2018) run.

GM changes transmission almost as much as they change gray exterior paint.

 

^^ Yeah and how long do people want to sit around and speculate on what's next instead of just driving what is here now.

 

You realize of course that you could get the A8 which has been around for years and still have problems. Anything is possible.

 

Oh ya?
What do you base that wild guess on regarding pricing?

 

Just tracked a Z06 Z07 A8 for multiple sessions and never once had an overheating problem.
75% or so of all Vettes are autos,
When driven full throttle mine shift like you were pulling a trigger, I love it its and don't see it as anything but astonishing but thats just me.

 

There is no excuse for the poor shifting on the 8 speed. I've driven Toyotas and Chryslers with an 8 speed and an Acura with a 9 speed. None shift as crappy when cold as the A8 GM.

 

10 speed.. what a joke.. my bicycle has 24 speeds!!!!

 

They could go back to a A6 but the gas mileage would be less and that is what extra speeds are for nowadays.

 

What is the probability that if the 10 spd comes to the C7 it will include stop\start capability? Apparently this is a design feature of the new trans.

^^^ I hate the Stop/Start technology. I know you can turn it off, however I drove a rental car with it and it's an unnerving feeling when your in the middle of an intersection turning left against oncoming traffic.

 

The trans was designed jointly by GM and Ford. Allowing a design that could not be used in the company's performance icon would make no sense. I fully expect it to be available in Corvette - even if in limited volume - as early as MY2018.

 

Just need a well integrated system.

Our BMW SUV does it seamlessly. Engine starts when your foot leaves the brake. It doesn't have to hit the gas. (Perhaps left foot brakers would have a problem. Never did that and it was recommended NOT to use that when I took driver's ed. That was very long ago!)

Sure I could turn it off but statistics show 17% of the energy in gasoline is wasted idling! Why not.

 

If GM uses that first gen A8 torque converter on the A10... then it won't t bode well either.

I mean, the most common failure for the A8 was not the tranny itself, but the TC.

 

I don't know why the A10 would change anything. Its the same sales lines they use for the A8, up shifts faster than dct, etc. It shifts faster, but the thing is, it has to shift more often. At some point adding more gears is counter productive. Also, the A10 still uses EC3 technology, which appears to be what fries the TCC in the A8. We'll see what happens with the ZL1's, but I am worried people will have problems with the A10 too.

I went to the Camaro forum and read what the ZL1 guys are saying. So far they love it. I also see it has a +/- on the shifter, which is very nice. The paddles are not always the best way to shift.

 

What is next after a 10 speed-a 12 speed? then a 14 speed, etc.?? Why not make a 6 speed auto that correctly mimics a 6 speed manual without a clutch-seems like a winner to me.

 

The A10 seems bad *** on the ZL1 track reviews..

Hope this new tech comes to corvette...

Grand sport should get 500 hp...for added sales...the A10 trans would be popular as well..

Time for GM to up the hp for added sales in showroom...I'm sure street or track performance would be identical to present 460 hp LT1...

Hp sells...and sales are off a bit this year...

Dealers are loaded with grand sports in inventory...great car but unit sales are dropping...

Change , upgrade , and hopefully increase sales...this is year 4.....(stop the sales slide)

Hmm, if I couldn’t buy a manual I would look elsewhere! My Grand Sport on order will be my 5th Vette. Have only had a standard trans in all my DD’s for 55+ years!

Regarding added hp, must be careful what you ask for! Needed a pick-up when we were building our current home so bought an entry level bench seat Chevy S-10 truck with a V6 and 5 speed . Liked it so bought a step side S-10 with bucket seats, all the HD options, quick steering, HD suspension, positraction, lowered with aluminum wheels, extra shock controlling axle hop etc. It also came with an advertised ~20 more hp from that shortened small block V6. Thought that would be great.

Found I was having to slip the clutch and use more throttle to accelerate into the 65-mph traffic on the divided 4 lane highway at the end of our street! Brought it to the dealer and the service manager took it for a ride. He came back and said, yep they increased the power at higher rpm’s for sales reasons but gave up low end torque!

Fortunately, he was a drag racer and said, I’d suggest getting a Hypertech programmer! I did and set it at the 93-octane required program. Installed their suggested 160-degree thermostat and added a Flowmaster, larger crossover pipe (which GM had flattened reducing volume 30% to increase ground clearance!) Also, installed colder plugs, an MSD ignition and a cold air, low restriction intake. It was like a different truck! No more slipping the clutch to enter the highway.

Chevy's recently released LT376 is a good example of what might not be the best way to get more power from an LT1 for street use (it is only available as a create motor.) Although higher hp it’s only 5 more ft-lbs of torque. It also eliminated variable cam timing to accommodate the higher duration cam. Yep they could increase the power of the LT1 but if only at higher rpm’s may not make a great street car addition!

If 20 more hp would accomplish the sales objective they could add a low restriction exhaust, intake and tweak the cam. I'll install the larger, lower restriction oiled cotton air filter and intake duct in my Grand Sport that I removed from my 2014 Z51 before it was sold! But more for the increased "sucking sound" than the increased power! GM does have restrictions on intake sound levels, I don't.

Agree added hp on paper would help sales but hopefully it would not negatively affect street performance.
