First let me start by saying my 2008 Black Z51 Automatic is my first Vette and I love it.
With that out of the way here comes the disappointing laundry list.

1. The automatic shift points are driving me insane. Heres an example I was at a light with no cars in front of me I started to go on green at a healthy rate of speed. A car coming the oppposite direction turned in front of me. I had plenty of room to just let off the throttle. I lifted and went to throttle up again and the pedal felt dead. I had no power to speak of. Another instance i was rolling at about 30 mph and stood on the pedal car downshifted and took off I let up at around 65mph and the car didnt upshift for what seemed like an eternity as all i heard was my poor LS3 screaming with the rpm's being pegged and no shift following. If this is normal for the automatics I dont know. Yes I know the paddle shift makes it better but that is not the point.

2. Transparent roof makes noise. Thats nothing new have seen all the posts here on that one.

3. At least 4 paint blemishes. There 4 that I have found where it looks as if there is not enough black paint under the clear coat. When direct bright sunlight hits those spots they are very visible. They are round in size and are about the size of silver dollars. Two are on the passenger side rear quarter panel and 2 on the Driver side rear quarter panel. They are not in the same location from side to side either.

4. Right rear whell chrome is sligtly pitted. Enough said.

5. 50% of the time i press the switch to turn off the ignition the FOB is not recognized. Its in my pocket mere inches from the dash.

Theres my list anybody have any thoughts or similar problems?

 

Nope. Sorry, 8th vette, not one problem.

 

You should of got the Manual 6. for total power control.

 

Sorry for your troubles. On the A6 shift points, you do know that if you are in auto mode (no paddles) and you come to a stop, the car only shifts down to second? If you want first, you need to put it there. This may explain why you don't feel as if the car is responsive under that situation that you mentioned. You are likely in Second, not first.

GM is working on roof noises and you may want to contact the plant. You can reach them here:

You might mention the paint blemishes as well. They are very interested in feedback and will likely contact you for photos and specifics.

 

I didnt want to have to be shifting all the time. Hindsight the manual trans is the only way to go but I ve got what I got. The automatic is the worst trans Ive ever driven as far as power management goes. My 06 Monte Carlo was better.

 

That is true. But the problem was after I let off the throttle and attempted to get back into it. The car was flat no power at all.

 

1. Mine seems flakey also. No wait. I have an 07 and your 08 is supposedly vastly improved. I'm always waiting for it to shift up. On the other hand, I have a Pontiac that always shifts too soon. At least the Corvette is adaptive. The shift points change based on how you drive it. And it also seems to me that the adaptation is different from D to S. When I first got mine it was fine in both. Then I started using S only and it learned what speeds I drive and how I accelerate to those speeds and it adapted by running higher RPM. So I shifted to D and it was fine for a while but now delays upshifting again.
2. Silicone heat sink grease from Radio Shack.
3. One more reason I will never buy any black car.
4. Don't have an opinion. Mine are fine.
5. Get the FOB away from the dash. The receiver is in the door column. You also weren't in the recall for bad FOB receivers, were you?

 

Didn't you mean if you are in S and have been using the paddles? If you are in D or in S but haven't used the paddles, it goes to first when you stop. The only time it stays in second is if you have paddled but not down to first. It's just doing what you told it to do. i.e. you told it you wanted to do the shifting but you didn't tell it to go all the way down. If you don't paddle S and D are the same except the shift points are higher and harder in S.

Even a start in second shouldn't be "flat, no power". I'm thinking it started upshifting when he got off the throttle and then had to downshift when he got back on and it just took time to get that done. The computer will hold the throttle back in D especially when it is in the process of shifting. That is the make the D shifts smoother. I like the sound of D under hard acceleration because it sounds like a manual taking your foot off the gas and then getting back in it after the shift.

 

Sorry to hear you are having problems.
Mine has none!

 

No problems with my 2008 A6 [thirty days], and much smoother and better shift points them my 2006 A6.

Regarding, "On the A6 shift points....."

I thought that would only happen if you had previously engaged the paddles, and that it would shift down to first, either in D or in S if paddles were not engaged.
Please confirm for me.

 

There is a recall on this item. Take it to a dealership you feel comfortable
with and leave it with them for 1/2 a day. They will have to pull your
dash apart. Also, they will need to order the part.

 

AFTER you do the bowling green assembly plant website, you may be visiting your dealer for all the things you mentioned. not sure where you live due to your profile, but hope there is more than one dealer in your town in case the first one can't solve the issues you mention.

 

All of my shifting issues have occured in the D mode. The one with no response felt lik the car was in 6th gear at 30 mph

 

Im in the suburbs of Chicago so I ahve plenty of Dealers nearby. The dealer I bought the car from is pretty good. Small dealer though not sure how good they will be with a vette. But I do trust them. they are Good People first and a Car Dealer second.

 

that sounds good. kinda wish all people were that way, but glad you found them!!!

 

Forgot #6
Driver window leaks between transparrent roof and window when high pressure water is sprayed directly on the window.

The first tranny prob mentioned is what I call a coast down glitch. I have the same thing on my 07 A6. I think its the way the trans is set up, not a defect. It happens during around town driving at speeds under 20 or 30 mph and so far only in D but I havent tested for it in S yet. It feels like an accelerator pump lag problem on a car with a Carburetor but in our case its not engine related. You let up on the throttle to coast and then when you press on the throttle quickly nothing happens for a second. Its as if tranny is inbetween gears and can't decide whether to downshift or up shift.

If you are granny driving you would never notice it because you don't press on the throttle quick enough demanding snappy acceleration. This condition is not ideal for a performance car but it may be the nature of the beast in D. It dosent happen continually, just under certain parameters. Anyone have it happen in S?

I haven't tried a WOT demand under these conditions so I don't know what would happen.

I adjusted my shift time between gears 20% faster and it made no difference on this condition but at WOT shifts it got rubber during the 1 and 2 shifts and the car leaps forward between shifts.

The WOT problem mentioned does sound like a defect and it has never happend to me.
