Towing over max gross? How did it perform?

I don't think the engine or the transmission would limit the towing capacity. I don't have the Ecoboost and the engine still has a lot of power. This kit could probably be able to tow a lot more. I think the frame is the limit. I wouldn't tow 8000 pound with the Flex cause i'm sure the frame would be thorn away.
Hope this helps!!

Thanks Fredee. I agree that the structure of the vehicle is likely limiting. I just notice that the campers that I am looking at are right up there at 4500lbs or so empty and I really don't want to settle for a pop-up style.
That's some great guessing, but it's wrong. The Flex is limited by it's cooling potential. Unlike a big truck, the frontal opening of a Flex is small, not a lot of air goes through the radiator and other coolers. You're not going to bend any metal by towing over 4500lbs, but going up a grade in the desert could result in some unplanned parking on the side of the road.

So, take precatuions, add oil temp sensors for engine and transmission, add additional oil cooling capacity if temps get over the 180/190 deg F mark.
This may not be the limiting factor, but from what I know, it is likely one of them. The others are going to be brakes, engine cooling capacity, and the ability to take the load of a weight distributing hitch through the suspension and still have acceptable vehicle dynamics.
Overall the Flex is an OK performer when towing close to the limit. We tow a 3200 lb pop up and when loaded with gear, it's close to 4200. It performs well in the Southern Ontario, Central Ontario, Northen Eastern New York region, but than again we dont have long grades that really test it.
Good luck with whatever you end up doing.

To be honest, towing in Michigan at less than 90F shouldn't give you any trouble with transmission temps, though no guarantees! The Flex already has a transmission cooler that's integrated into the A/C condenser, so it's not easy to add anything more as you have to T into the existing lines, and that can cause flow issues.

Here is my take on this. The weight isnt the real issue here, you can have a small trailer and load it to far exceed the towing limit, what you must consider is driveability. I have a 2 horse bumper pull trailer, its gross is 7500 pounds and empty weight is 3500. I used to pull it with a 97 Explorer AWD V8, it pulled and stopped it fine with 2 horses in it. The issue came when on the interstate, and passing or being passed by a Semi. The push/pull from the truck going by would cause the Explorer and trailer to sway, and if you have an aftermarket hitch installed and not the factory, the sway control is not installed, so you must give this consideration due to the short wheel base, especially pulling a big box behind you. The factory Tow package includes sway control, but it may not be enough to counter act the sway I am referring to. It can get out of control really fast, especially if you are one of those who tends to drive above 60 while towing. That sway could start out as a little move, but can quickly amplify enough to cause you to jack knife if you dont know how to correct it. Most times lifting your foot off the gas will stop it, but some people will have the knee jerk reaction of hitting the brakes, and then Instant crash can happen.
Not saying dont do it, but driver beware of this issue with the short wheelbase of the Flex and a larger boxy trailer. I had rented a dump trailer and pulled it with an F150 and that bugger started to sway even with the large pickup. Was not fun, but I was able to stabilize it and just slowed down.
