First thing I would do is get under there and check the fluid level. No dip stick, so you have to get it up on ramps or four jack stands (be safe). Car must be level! Run the tranny up to temperature and remove the filler on the bottom pan. You will need a hand pump to pump fresh tranny oil in there until it starts to come out.
Actually, I would just go ahead and replace the fluid and filter. You can do it yourself if you can get it up in the air. It is a pain, but can be done with jack stands.
Another alterntive is a fluid exchange, but not many people here like that option. For you, it might pay to use the pull the pan and filter method so you can see if there is any metal shavings in there. Fluid exchange will not tell you anything.

I'd suggest going to your friendly dealer and asking for a printout of the service manual pages that refer to checking and changing fluid and filter. The pictures alone tell a good deal.

Mine has done the same thing for the past 2 years, only when cold and usually the first 3-4 shift. Then its fine. It never hurts to check fluid level. I now mine is OK. If you not seek a leak while under the car or on the floor, chances are you fluid level is OK.

I am sorry to hear that you are noticing some slippage when shifting from 3rd to 4th when the transmission is cold. I would be more than happy to assist you if you were interested in have a dealership look into this concern. Please private message us if you would like to further discuss that option. Thank you very much for taking the time to read my post!

Mine is an 06 with 33000 miles. I have had no worsening of the problem. It does it only once when cold, then good to go. I'd be interested if you took up the offer by Chevy Customer Care to see what they think. At this point I don't consider mine a problem. I just keep an ear on it.

My guess is that until the fluid gets hot, the level is a little low...then the fluid expands and the level goes up a bit. Hydra-matics have been sensitive to low fluid level since the 60's.

Have noted similar shifting issues in my 09 A6...I have had two over the past several years and think it is a common problem for the A6 in general. I can't say its a "fix" but just took the car in for a tranny filter and fluid change at local dealership. Even though it has just 8K on the clock its about 5 years from its launch so its getting time to dump some of the old fluids. After the fluid change (didn't flush) the transmission seems to shift smoother. Call it the placebo effect, but the seat of the pants digital computer tells me its better, so it must be so. The tranny filter and fluid change will make it to my ever couple of years calendar of major events for maintenance.

For what its worth
Just a filter and fluid change by a pan drop will get less than half the fluid. You don't get what's in the converter.
A total fluid exchange through the cooling lines gets 100% of the fluid.
The best deal would be to do both. Although more costly.
I would do the total exchange first. That way you are not running worn dirty fluid through a clean filter.
Now you would have all the bases covered regarding the fluid.
