Your posts are all the same. Glad to see you changed your SN and avoided eating crow while anyone was watching.

How many times have you been banned from this site?

TT C6
TT AWD

Or something to that effect. You lower the quality of every forum you join, and you've been banned from just about every one multiple times. Why can't you just relax?

Bc I've always felt the whole "paddles shift" thing is kind of a gimmick anyway. I'd bet that's why when people run their a8's at the track just leave it in drive.

I consider it to maybe not be a "game changer" but I definitely think the a8 is a big step forward over the a6. It shifts quicker and to my knowledge is the first auto that can CONSISTENTLY beat it's manual counterpart. Is that not progress to you? when I had my a4 ls1 ss, I was able to get 13.2's consistently out of it but properly driven m6's would produce quicker times, same way with the a6 in the vettes. Stock for stock my m6 would show tail lights to any a6 I ran. I'm sure the a6 is a great transmission, but from a performance aspect, a properly driven manual produces better times.

Those of us who have driven PDK, know better, and will never accept that garbage A8, or the lies that GM sold trying to compare it to PDK.

I am sincerely hoping that the A10 is a game changer.
If so, I will gladly trade my 2016 SS M6 in on one.

PDK is nothing special. You will figure that out at its first scheduled maintenance interval.

I've never driven pdk, so I can't compare the two. I can compare gm's previous transmissions to it and I definitely think it's a step forward.

Since I don't have any experience with pdk, what exactly are the differences?

PDK is a well put together electronic controlled clutch style transmission.

So why does GM not abandon the torque converter approach?

Most applications where the PDK is used, does not have to handle the torque that the GM V8 delivers. remember, even 911s that are way over $100,000 don't even break 300lb-ft of torque.. Next, maintenance intervals are VERY expensive. Another point is smooth operation for street compliance. Last, is overall price of the unit, for porsche the PDK is an expensive option on an expensive car.


It just does not fit in this demographic and offers very little advantage vs cost of a PDK that can handle over 450lb of torque.

Amen. PDK is nice, no doubt about it. But is does not handle high torque well nor make your wallet real happy when service time roles around. My brother-in-law owns a GT3 and he told me how much the maintenance on his PDK was and I laughed so hard it pissed him off to the point he did not come over to my house for his nephew's (my son if you are playing along at home) birthday party later that weekend. Anyway, we are cool now but let's just say the only thing Porsche is more proud of than that transmission is the tech's that work on it. :-)

While I haven't driven a PDK, I will take the A8 all day long over the 7-DCT I had in my 335is. Sure, it shifted a tad quicker but it wasn't all that noticable, the A8 is still much faster than you could manually shift the M6, and for daily driving the A8 it is light years better than any DCT will be. And with just a tune I was worried about clutch slippage on it as they weren't rated for much torque.

If I go with the 1LE, I'm obviously going to be getting the manual but if I spring for the ZL1, it's the A10 for me. Especially with a 5th gear 1:1. I can't wait to see what the actual ratios and rear end ratio are.

The quickest C7's are actually the A6's, not the A8's. The #1, 2 of the top 3, and 5 of the top 7.

on corvetteforum.com #1 has an a6 and #2 has an a8, who is .005 slower yet 3mph higher trap speed. 6 of the top 10 are a8's, and apparently they have two #8's lol. My comparison was that the a8 shifts faster than the a6 and this transmission, along with a few less pounds, gives a camaro6 almost identical acceleration to my m6 ls3 c6, which would beat an a6 c6. It's my opinion that it's a step forward.

But I still would like to know what makes the a8 a "garbage transmission"? I've heard how pdk is better but have gotten no real reasoning as to why it's garbage. How fast can pdk change gears and how fast can an a8 change gears. Surely if we had exact units of measurement between gear changes we could say gm lied, but I haven't see any such evidence.

You're not likely to...

I guess different forums, different lists. Still holds water tho that the A6 holds more than 1/3 of the top 10 while the 15's and 16's hold less than 2/3's. I'm not saying the A6's were better than the A8's, just that in a straight line, there is little to zero difference.

I agree with that, but the conditions under which those cars ran could vary greatly. I'm not trying to make any excuses, but the only way to truly know would be to run them under the same conditions, much like these independent testers who run the m6 camaro6 against the a8 camaro6 and are reaching those results.

But if I bought a car with a transmission that'll need replacing as much as the oil, I'd surely like to know since my thought process when buying this car was "holy shit this shifts quick". And I never read gm's claims to what it's supposed to do.

Don't take my word for it, talk to anyone who's driven both the PDK and the A8.

Ok, so your reasoning for the statement of "the a8 is garbage" is based solely on the paddle responsiveness?


I can live with that....I plan on modding this car rather heavily and if my only complaint about the transmission is "man these paddles that I don't really use aren't that responsive" then I'd certainly be happy with that
