Manual says every 100k
or 50k if this applies:
(h) Change automatic transmission fluid and filter if the vehicle is mainly driven under one or more of these conditions:
• In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher.
• In hilly or mountainous terrain.
• Uses such as high performance operation.

Vehicle fluids are relatively cheap for preventative maintenance. I'd personally never drive more that 60,000 miles or max of 7- 8 years on factory trans & diff fluid, under non-extreme conditions.

I found that this work is MUCH EASIER than I thought it would be. I do have a set of QuickJacks, however, which make any work a lot easier.
I have even checked the level with the engine running while I was under the car. No big deal. Regarding the circumstances that C6ToGo mentions, I have done all of that, I have 77,000 miles now, and I'm the third owner.
It was a no-brainer to decide that it must be done. I have not dropped the Pan nor changed the Filter, but I have flushed what is possible twice now, and will do it a third time soon.
And this Mity-Vac device takes care of the rest:

I would do it. That fluid, if it's still factory, is 15 years old. I know people like to go as far as they can on fluids but as I started buying vehicles with less miles to start, the more preventative fluid changes I started doing. I'm not sure how the C6 autos are but I would assume it's like any other and that I would just drop the pan, put a new filter in, and fresh fluids. My manual Vette I change the trans and diff fluid every 2 years myself. I know it's overkill but it's easy and not that expensive to never worry. I'm the same with my other vehicles as well. Good luck

I made the decision two weeks ago to change out all the fluids on my 2012 CE. I just passed 75K, am the 3rd owner, and looking at a record-breaking summer heat wave ahead. I was ready to do it myself when the dealer sent me a flier for 15% off any maintenance work. Way too hot here (115), so I let them do it. Cost was $770, and well spent for peace of mind, if nothing else. BTW, the A6 now shifts like butter...cannot feel the shift under light throttle. So glad I had this done.
Coolant flush/fill
Brake fluid flush/fill
Oil change
Power steering fluid change
Rear diff. fluid change
Trans. fluid change
I told them not to bother with the windshield washer fluid...

a good shop will have the correct tool to suck it all out. Or if your a DIY guy you’d have the correct pump for it.
I just had it done last week. I supplied all the fluids. Amsoil. And cost me 133.00. Diff was 75.00. Fluids cost the most with my discount was 287.00.
