How do I change the automatic gearbox oil in an Audi A5?

I'm looking to perform a routine maintenance task on my Audi A5's automatic gearbox. Can anyone provide detailed instructions on how to properly change the gearbox oil?

First, locate the drain plug at the bottom of the gearbox and remove it to drain the old oil. Then, locate the top fill plug on the side of the gearbox and remove it. Use a funnel to pour in the new oil until it reaches the bottom of the fill hole. Finally, replace both plugs and you're done!
