Audi C5 A6 2.7T Automatic Transmission Fluid, Filter and TransGo Valve Installation

In this video, we replace the transmission fluid and filter in a 2004 Audi A6 2.7T S-Line quattro. We also remove the valve body and install the TransGo valve during the service. This valve is designed to help prevent pressure spikes within the valve body that can cause catastrophic transmission damage. (Or at least that is my understanding.)

You can find fluid and filter on a variety of auto parts stores. I wound up using a Febi kit. I prefer ZF Lifeguard fluid or the Febi Bilstein fluid used in this video as I have used both with success in the past.
If doing just fluid and filter, I'd plan on having about 8 liters on stand-by. In my case, due to mishap and partial re-drain and refill, I used ~12 liters in total.
