Whats the deal with the 14 a6 cars trans...why dont they shift like the 6l80's in the c6s..they all have a delay between each shift mainly 1st and 2nd and 2nd to 3..it actually seems like it kinda kills the momentum..you can even here the delay in videos on the net..is that helping the trans live? And also is that able to be tuned out to have sum good non delayed shifts??the a8s dont do either

I think many people here will have a hard time understanding what you're talking about, it seems to me like the A6 shifts pretty dang quick.

Do you have a video example? Is this something that your car does? Doesn't sound right to me.

With the delay the wheels actually try to pause the next gear comes in..im gonna find some videos

This might be different between different A6 cars. Before I decided on the M7 I drove the A6. Had a very similar experience (sluggish/stuttering A6) and felt this in different modes to varying degrees. This reinforced my M7 choice and pissed me off since I wanted my wife to drive the car and for that I needed an auto.

Also disliked the annoying click clack sound from the shift paddles.

About 6 months later I drove another A6 and it shifted fine! So who knows what that earlier experience was all about.

Maybe if you took a vid of the DIC while your driving that could help others help you

Are you stock or tuned?

Whatever it is...........not slowing down the A6's. Unless you tune your car, this is probably all you're going to get out of the A6. If you actually believe that it's something serious I would take it to the dealer.

Its all the a6 cars ..they dont have a consistent shift as the c6 autos...mine is stock i will be getting it tuned but they do have slight pause between shifts..drag racing its noticeable with a close opponent

I know this 1 is blowing thru the converter but it the burn out u cb an see the delay in the shift and how it shifts

They clearly shift diff

I have a 2014 C7 Base Convertible with the A6, It has no lag on upshifts, ask the guy in the GTO with the $15000 6.8 stroker crate engine I met up with the other night, and that was when I was already rolling and the tranny needed to kick down, sometimes there can be a delay on downshifts. From a dig there is no lag between upshifts.

I do think Chevy built in a timing or slight fuel cut on shifts, that might be what you are feeling, either that or Traction Control or Active Handling kicking in a bit.

I hear the same complaints on the A6 and A8, but both of these trannies are running 11 second quarter mile times and cutting 1.6-1.8 60' times in the C7 with trap speeds in the 118-120 range, I can't see there being too much of a lag.

You could get a tune for the tranny and take out any delay between shifts, but this might slow you down as you will break traction.

My buddy has a 2014 5.0 automatic, ran a 12.9@110 bone stock.
Tuned the tranny to shift harder and faster on the 1-2 and it was slower due to breaking traction, I told him to soften up the 1-2 shift and it immediately went faster again.

Makes sense to me, Yell03. If there is a delay probably for a reason.

hnaskoct

Maybe thats what it is. Timing and fuel cut..that sounds like it makes sense..but between both cars they def are diff between shifts whatever it maybe..

I know I read it somewhere.

I have had times where I have floored it from a dig with TC on and there was a delay even before the tires started to spin, but I think that is just TC and the drive by wire being over cautious. If that happened with TC off, then there would be an issue.

Do you mean using the paddle shifters?
In Auto my slaps them off with no problem.

Correct......and actually it doesn't bother me

The C7 A6 shifts quicker than any auto Corvette ever before--- But not at P/T--you must have the RPM's above 4000 in order for the shifts to be quick--
The new A6's utilize a millisecond fuel cutoff in order to get fast shifts--this was never done before-- Under 4000 RPM the fuel cutoff does not happen -You can recognize the fuel cutoff by hearing a rapid sputter in the engine
Below 4000 RPM the TQ management system softens the shifts to promote trans life---
You CAN tune your A6 to shift quicker below 4000 RPM's by getting a full tune using HP or EFILIVE-- By-----Shortening the "desired shift times"----Softening the TQ management-- increasing the TQ response tables--increasing the "minimal final timing tables"--- driving the car in Sport or Track mode as well helps
