How many are you waiting for the 10 speed? I think it sounds cool on the ZL1 videos.

You'll have to wait for the C8 Vettes. GM rarely makes radical changes to the drivetrain during the model year run.

The 2005 C6 had the A4. The next year it had the A6. The first year for the C7 had the A6 and the next year it had the A8. If GM is consistent they will put the A10 in next year and leave it until the second year of the C8 which will then get the DCT.

Nah.

Good points

I think I'll keep shifting my Manual and wait till I'm in my 70s for a auto

They have to put one in because you can't have ZL1's running them two years and not Z06's. Those guy's at Camaro forums have no complaints.

The sound and performance is incredible with those cool downshifts/upshifts at high RPM wow what music!

I'm buying a 13-speed C9

I don't use 5-7 now. Too much shifting.

Yeah, I think the A10 is enviable.

With a Torque power band as wide as the Mississippi on the LT4 why would anybody want more gears???

I would like to see it out for a year before jumping on board and like others the A8 does a super job. In D I see 7 and occasionally 8 but generally am in M and end up mostly in 4, 5 and 6.

It has been out on the ZL1 smooth as silk

HighBeta

Not I: I am enjoying my 8 speed.

I'm sorry, but we will NEVER see the a10 in the c7. It will not fit the current car without a shorter torque tube and rear bulkhead modifications similar to what we do for 4l80 conversions. The a10 fits into other vehicles easier because they have a trans up front/diff in the rear and a driveshaft in between that can be shorter.

pkincy

Actually it has not. Deliveries are just now beginning. It may be smooth as silk and it may hold up to the power, but we don't yet know that for sure. Also the tuning algorithms may be great and they may need tweaking like they did on the A8.

Pacembellum

Does it have 3 pedals?

I had a 10 speed when I was a kid. And then a 21 speed. Does that count?
I'll stick with my M7 gearbox

Someone from a well respected perforamnce shop told me the 10speed may not fit in the current c7. He wasn't 100pct Sure but i do value his opinion

Do you have the length of the A10? Everything GM has put out says the A10 is the same length and fits in the same space as the A8. The problem with the A10 being used in the Corvette right now is it isn't a modular transmission, it doesn't have a separate bellhousing from the transmission case like the A4, A6, and A8. Your 4L80 conversions are made difficult because that transmission has its roots in 1960's technology with an addition using 1980's technology to add overdrive, it's physically a very large transmission. The 4L80 is an extremely strong transmission because technology in the 1960's said to make everything bigger to make it stronger, it's a very large transmission physically compared to modern day transmissions. The 4L80 is also very inefficient, they require significantly more HP to drive them than modern day transmissions.

While I hope GM makes the A10 modular, it seems they would've made it modular from the beginning to save investment in new casting molds just to put it in the Corvette. I think it's unlikely to happen but I can still hope...

Because HP is what accelerates a car and the power band of the LT4 is narrow. The M7 and A8 are close ratio transmissions to keep the LT4 in its power band, more gears always benefit engines with narrow power bands and close ratio transmissions. The M7 loses to the A8 in a quarter mile/stoplight-to-stoplight race because 1st gear in the M7 is very low numerically...it was forced into that because of the close ratio gear set used. The A8 loses to the M7 in roll races/road races because the 4th-5th shift causes a large drop in RPM just at the speed where it hurts the most...as you increase speed, the gear ratios need to get closer and closer.

The A10 has a numerically high 1st gear similar to the A8 and 10th gear is slightly lower numerically than 8th gear in the A8. That means the gears are closer together and the huge drop in RPM between 4th and 5th gear are gone. The performance with the A10 would be significantly better than the A8 or the M7 no matter what race you're participating in.
