What Should I Know Before Changing the Transmission Oil in an Audi?

I have been trying to understand the process because I used to think transmission oil was something that only needed attention when there was already a problem, but I am starting to realize that regular maintenance may be more important than I thought. My Audi is running reasonably well at the moment, although I sometimes notice a slightly different feeling when the car changes gears, especially after driving for a while in traffic. It is not a major problem and there are no loud noises or warning lights, so I am not sure if I should be concerned or simply have the transmission inspected during the next service. One thing that confused me is that different people seem to have different opinions about when the oil should be changed. Some say to follow the service schedule, while others suggest checking the condition of the oil and considering the way the car is driven. I do quite a bit of city driving, with plenty of stopping and starting, so I am wondering if that makes a difference compared with someone who mostly drives on highways. I also came across the phrase Professional Audi transmission oil change guide while looking for information, and it made me realize there are probably more details involved than simply draining old oil and adding new fluid. How important is it to use the exact transmission fluid recommended for the particular Audi model and gearbox? Is checking the fluid level just as important as choosing the right oil? I have also heard that some transmissions need the oil level checked at a specific temperature, which sounds like something that could easily be done incorrectly by someone without the proper equipment. Another thing I would like to understand is whether the transmission filter should normally be replaced at the same time. Does this depend on the gearbox type, mileage, or the condition of the old fluid? I am also curious about what a proper service should include. Should the technician inspect for leaks, check the transmission condition, scan for stored faults, and take the car for a test drive afterward? I would rather understand what should happen before agreeing to the work because it is easy to assume that every workshop follows the same procedure when they probably do not. For anyone who has owned an Audi for several years, how did you decide it was time for a transmission oil service? Did you notice any changes in shifting before doing it, or was it simply part of scheduled maintenance? I am mainly looking for practical experiences here because I want to avoid waiting until a small maintenance issue turns into an expensive transmission repair. If there are particular questions I should ask the technician before the service starts, I would appreciate hearing those too.
