For some reason under full acceleration, my car has a tendency to stick in first gear when using the paddle shifters. I sometimes have to press the paddle shifter 2-3 times before it will shift. This is becoming a real issue because the car is failing to shift and causing me to redline. What is strange is that the rest of the gears shift just fine under full acceleration. What would cause this issue in 1st gear only? Has anyone else experienced this issue?

 

I too am having this problem. It just started two weeks ago, It does not happen every time but like you it causes me to redline and look silly. As if I don't know how to shift my automatic I may take it in for a look at the computer settings and see whats different. I have never had any problems with the paddle shifters (cars is two years old). I will keep an eye on the thead to see what comes of it.

 

If the tires are spinning when you hit the + (and you can't always hear the GY's spin) it will not shift into 2nd gear.

 

I had that happen a few times when the temps were under 40....

Tire spin = no upshift....

 

my 2008 does it everytime under full accel.

 

This has happened with no! wheel spin at temps above 65*

 

Allow myself to invovle myself...lol

I had that problem and it drove me crazy!! I took it to the dealer and nothing.

This is what it was. The A6 has a very short 1st gear so the revs go high real fast causing you to miss the line to shift (there is a delay as we all know) before it will not shift.


I noticed that competition mode will allow you to shift even with some spin! Just make sure you time it right.. you wont be disapointed!

 

i wonder if there is any TCM programming that will fix this?

 

I anticipate the delay in shift time and shift at 5000 rpm that way the car will shift at or just before 6000 rpm. There is no pattern of this shift problem as far as I can tell it is very random. I have had no problems in this matter for the first two years of ownership. Funny how it just starting to show up now. I have just taken the car to the drag strip a few weeks ago and ran it very hard many times. I wonder if that has anything to do with starting the problem. I had no issues at the track but in the fallowing weeks is when the issues started.

 

Only a split second will put you over the line. Its hard to gage that its done EXACTLY at the right time with the vette pulling like it does under full accelaration in 1st.

Try it with the Competitive driving mode on and make the accessment. The dealer did little for me... My friend "Crazy Pete" helped me more.

I shift kinda early under full accelaration under normal settings and a bit more agressive durring competitive driving mode. No problem unless I try to drive like comp mode on reg mode.

Sorry but thats the best I came up with and learned to love my car.

Good luck

So if I understand correctly, there are two things causing the issue. (1) car will not shift out of first if the tires are spinning and (2) the gearing is pretty steep in 1st which causes the car to rev to redline much quicker and the delay in shifting with the paddle shifters gives the appearance that the car is not going to shift - when it actual will.

I had no idea that when using the paddle shifters that the car would not shift out of 1st if the wheels were spinning. Great info guys.

 

I have not noticed anything. Maybe because I don't use the paddles.

 

I don't have any problems either when it's in Drive or Sport, only when using the paddle shifters.

 

Guys,

I am gaving the same problem. Paddle shifts works great until until you really climb on it. I paddle it at 6,000 and it doesn't shift until it hits the rev. limited cutoff and then backs down and shifts. Really kind of scary but it shifts fine when you have it auto. Did you see the Car & Driver June issue with a "rent Car Conv with 15,000 miles" that turned 12.6 116mph ? I can't wait to take mine to the track and see what it will really do!!! Goes anyone know if GM has a fix for this or perhaps someone else. I got a long way to go on my warrenty and don't want to screw it up!

I ask Chuck of CoW about that as I noticed that as well. If I'm remembering what he said correctly (Chuck correct me if I got it wrong) he said that if your on it hard in 1st and you hit the + to shift into second that if the trans cannot complete the shift before you hit the rev limiter, the shift will not complete.

Thanks Indy,

I guess that means I have to find the magic number of 5600 or so to push the button! Kind of defeats the purpose of the paddle shifter concept doen't it? Might as well leave it in Auto!

Is this only in 1st gear or this also happens in 2nd and 3rd? Have you tried to slowly bring the car up to 6000 and see if it will shift. I know there is a delay in the shift with the Factory tune and in 1st you almost have to press the up shift button at 5000 rpm to keep it from hitting the rev limiter because the car revs so quickly. In 2nd gear it is not AS bad but you still will have to shift 500 or so rpm before you actually want it to shift to have it shift at the actual rpm you want it to. The tune can be adjusted by Chuck or anyone else that knows what they are doing and able to make a ton better but it will never be INSTANTANEOUS.

With the car in Sport Mode and leaving it in Auto not using the paddles it will shift everytime right at 6400-6500 rpm. Or atleast I have never had a problem with it shifting in Sport Auto mode. Yes I know the paddles were added and can be used but really if you are drag racing just put in in Sport leave the paddles alone and press your Traction Contro/Active Handling button 1 time to put it in just Traction Control off mode. With this setup you will have your best shifts possible and if you do spin and the car starts to get a little sideways the Active handling is still on pretty strong and keep you going straight. In Competitive Driving mode the Active handling is so deadened that you will have your hands full if you get sideways going down the track.

 

I also have this issue, I find that leaving in S and let it red line on its own is better than shifting. I only use the paddles for spirited driving when I am on the highway or country roads. I find that it keeps the power curve where I need it for that type of driving, when in the mood, the rest of the time I leave it in S.

 

Adam & George,

Thanks to the both of you for the reply. Of course, I was not "drag racing" but doing a little showing off when this has happened. I am going to give Adam's method of taking it up and seeing if it will shift without the WOT method. Car only has a little over 5,000 miles so I am not ready to start palying with it while the warrenty has a long way to go. With Adam being in Dallas, I would like to know on now to get in contact with Chuck of CoW as I am a Newbie and don't know many people yet. A red Vette Conv. has been a dream of mine for a long time and I really am enjoying it!
Thanks again for the help!
Dan

 

It is much less likely to happen if you turn off traction control (as mentioned with the tires spinning it will not shift). I have HP tuners, and by making some changes to use the 2009 timing tables in my 2008 it now shifts quicker with much less delay in the paddles. It was tought to time it for fear of hitting the rev limiter when it refused to shift. I now find that I very seldom hit it because the paddles have much less delay. If your at the drag strip it is much better to use S, not the paddles.
