The official Ford way to add fluid is through the level port on the side of the transmission, the upper port is only used when the tranny gets its first fill at the factory.
Since the general consensus is that we:
need to change fluid more often than the manual says
The fluid vent valve on the top is often A ROYAL PAIN TO ACCESS
We need to access the level port EVERY TIME

It seems that a kit like that shown would be great.
Has anyone modified a Mityvac or similar to fit? And what parts were needed?
Edit - I could use a vacuum system anyways for other vehicles
 
After watching a couple of YouTube how-to videos it appears that there are some differences between the 2017 and earlier models. I did three drain and refill cycles on my 2.0L Escape at 24,744 miles. By my rough calculations, this should have left me with approximately 83% new fluid. The color of the factory fill fluid was darker than I would have expected at this mileage. My Escape has not seen any hard driving or trailer towing, and was not exhibiting any strange behavior.

After warming up the transmission and before draining out the old fluid, I was curious to see if the factory fill was up to the "level check" plug. I removed the upper plug and about 4 to 6 ounces of fluid ran out. I drained and measured the factory fill, it came to about 4.1 quarts.

As stated, I drained and refilled the transmission three times. I took about a 10 minute drive between each cycle.

On the final fill, I added exactly 4 quarts and despite being "cold" there was a small amount of fluid running out of the "level check" plug when I removed it to check the level.

The fill hole requires removing an air-vent plug that is held in place by a hose clamp. There is a rigid plastic hose that runs from the bottom of the air filter box to a rubber "Y" junction at the front of the car. Remove it for easier access to the fill port and plug. I have attached a photo of the hose.

The "level check" plug is located on the drivers side of the transmission just aft of where the axle shaft attaches to the transmission. You will need a 10mm Hex Key to remove it. I have attached photos of what the plug looks like, and also posted a photo of the "level check" plug location.

The "severe service" maintenance schedule recommends changing the transmission fluid every 30,000 miles. Despite having driving habits that would put me on the "normal" maintenance schedule, I will be servicing mine at 25,000 mile intervals. With the appearance of the fluid that I drained out, I expect that anyone who follows the "normal" service recommendation of the first fluid change at 150,000 miles will be in need of a new transmission a lot sooner than expected.
Thanks for the photos! I'm curious as to why Ford didn't install a dip stick like every other car I've owned.
 
To make life easier and not waste fluid get a 4 qt. container and just drain out 4 qts., put back the drain plug, then refill with exactly the same amount drained. Do the drain and refills 3 times. No more guessing. The dilution should be sufficient. No need to recheck fluid level. Extend the fill/vent port in the engine compartment with a piece of light duty hydraulic hose and secure it with a hose clamp at the bottom to the fill/vent port. Get a brass or aluminum MxM hose barb and secure one end to the top end of the hydraulic hose. Secure the vent cap to the other end of the hose barb when finished. Saves time and for future D and Fs as you don't have to remove the air box or buy special pliers. The vent cap will no longer be buried making it now readily accessible. The 1st gen 6F35 transmission used until 2012 is not that complicated of a transmission and the fluid stays pink or red longer for whatever reason during normal driving. The 2nd gen 6F35 transmission used from 2013 to present is more complicated. The fluid turns darker sooner depending on driving habits. Has more solenoids and electronics. Also, has narrower passages internally for fluid to flow through. Especially for the 2nd gen 6F35 transmission use only MC Mercon LV or equivalent, "RECOMMENDED", licensed fluid. Stay away from any universal fluid that states "Suitable."
