Default A6 Trans - Shifting Problem Battery Related??

For the past several months my 2008 A6 was shifting poorly between 1st and 2nd. When going around a sharp corner or cruising in a neighborhood it would hunt between 1st and 2nd gear producing a rough shift and sorting of jerking when it would catch 2nd; almost like it wasn't sure what gear to be in.

I just replaced my battery as it died yesterday, it was the original 36 mos Delco, to a new Duralst Gold, and voila, problem seems to be gone. Shifting seems to be as it should and it doesn't "hunt".

Is this possible or sound remotely familiar to anyone? There was a TSB out a awhile back about this and when I took it to the dealer of course they said they couldn't duplicate it.

Feedback would be appreciated so I know if it may be something else if it starts to do this again.

Thanks!!

Thunder8,

I'm sorry you are having shifting issues. Have you taken your Corvette into your dealer for this? Are you past your mileage on your Powertrain warranty?

I have about 45K on the clock and I thinks it's a 5 yr/100K, is that right? I did take it to the dealer about six months ago and they said they couldn't duplicate the problem. Unfortunately at the time I had to work and couldn't do the test drive with them.

I don't know how they missed it; it does it every time; for example on a rolling stop situation. Once up to speed, say above 40mph, it's fine an doesn't do it. Again, what the drivetrain warranty time and mile limitation? Do you know if there's a TSB for something like this?

Thanks for your reply.

Thunder8,

The Powertrain warranty is 5yr/ 100,000 miles. I would suggest taking your vehicle back into the dealer to have them check out the issue again. Also, suggest ridding along with the tech so you can explain it.

Thunder8, I'd suggest you ask dealer about "2nd design oil pump" related to shifting problems.
