This is good to know. Thank you for the how-to.   I bought my 17 new with the cup holder fingers loose. Warranty replaced the entire assembly. Was probably this same tab broken. Luckily this has not happened again, but good to know how to fix it if it does. 

Yep, this specific tab (red arrow) that the rubber band wraps around, broke free slightly to allow the rubber band to come off.   Now I know why the cupholder retainers weren’t working and we’re rattling in the car.  A little JB Weld should repair it so I can wrap the rubber band back around it. 

I have a 2024 Edge ST and I would like to add the factory perimeter alarm ML3Z-19A361-A. Does anyone know if it’s a simple plug and play or if I need to get it coded? TIA

Interesting.  Any idea as to how the band came loose?

I figured it out. See the photos below for the proper routing.  I had one of the small broken tabs that needed to be JB welded back on.  That’s why the “rubber band” came loose.  Fixing it now.  On the first photo below the cup holder on the Right-side in the photo is a mirror image of the loop on the left.  I was repairing my tab so I didn’t show it.    

So I took my cupholder apart on my wife’s 2018 Ford Edge because the beverage retention tabs weren’t working and loose.  I found out that the clear colored rubber band had come loose that pushes IN all the retainers to hold beverages in the cupholders.     Does anybody have pictures or a diagram of how this clear rubber band is supposed to be routed around the cup holder retention tabs???     It looks like it goes around every tab twice at the top and bottom    

Give your owner's manual a browse - I find the downloaded PDF to be most useful because it has the word search feature - search for "Scheduled Maintenance".    

In that case they did only one drain-fill which isn't worth much - most would do at least 3 drain-fill and even then, its only about 60 - 80% replaced.

11.62 Qts (11L) (8F35) 12.15 Qts (11.5L) (8F57) - ST   The rest of the fluid will remain inside of the torque converter, transmission internal passages, and cooler lines.   The owner’s manual states to change the automatic transmission fluid every 150,000 miles.   However, if you operate your vehicle primarily under the following conditions, additional maintenance is required. Change the transmission fluid every 30,000 miles: Towing a trailer or using a car-top carrier, extensive idling or low-speed driving for long distances, as in heavy commercial use (such as delivery, taxi, patrol car or livery), and operating in dusty or sandy conditions (such as dusty or unpaved roads).

Got the bill and they charged me for 4.5 quarts of ULV. How many quarts does it hold?   The trans shifts fine without any issues.
