Both filters were similar to a sponge. I will cut the old one and post pics later. I will not wait this long again to change.
Yes dirty fluid is not horrible. But its my truck and i like clean fluids. An inline gilter would help extend fluid life.
I used a small hose from the fill plug up to the passenger manifold. Very little spill.
Lots of good info guys. Im just trying to help too.

The dealer dropped the pan and changed the filter while replacing the bulkhead electrical connector(common leak point on the 6r80). The invoice showed 5 liters of Mercon LV replaced so it still had a lot of old fluid in it.
I pulled the upper hose from the cooler and found out which way the fluid flows, then attempted to run the engine to pump out the old fluid, while sucking fresh fluid from a second container. That failed because there is a thermostat on the cooling system that will not allow fluid to be sucked back in unless it is above 172F (i think that's the thermostat opening temperature).
I then pumped out 2 liters at a time and refilled the pan with exactly 2 liters via the dipstick port under the truck using a funnel and hose. It took a long time to get through this procedure enough times to start getting clear fluid out of the cooler, 7 to be precise, but I wasn't in a rush and it worked out fine.
As a matter of info, the fluid pumps out of the upper barb (right, driver's side) of the cooler mounted up front (this is still the same on my 2013 5.0l work truck) with the engine running, but will not draw fresh fluid in unless it's fully hot. The hoses are all 1/2" inside diameter and a 1/2" magnefine filter will work just fine on the output side of the cooler.

I'm guessing here ! Not What to Do Today clause is in effect immediately !

On the passenger side of the tranny near the front on top of the pan is what looks like a large bolt. Its a 19mm plug for the transmission fluid dipstick. Remove the large looking bolt and under/ inside is a small 5 inch dipstick.

Z7What - How are y'all refilling the tranny? According to my owners manual there's no dip stick!

tcp2 - On my 2009 5.4l I can disconnect the hose (#1 in the last diagram) and fluid comes out of the aux cooler as I have to add a piece of hose to direct it into the catch jug when the engine is running.
