I seem to remember a wrench and I have read of Throttle Body issues. It seems like sometimes it is searching a bit on acceleration and Ford has had many claims on the throttle bodies in various vehicles. That was on my mind to stab at since they are reasonable in cost but wanted to study aftermarket and maybe enhance the power some.

The PTU is 100% mechanical, nothing intermittent can be associated with it Same with Rear Differential, there is an electric "clutch" that allows torque to be applied to the pinion gear. I'm not 100% sure but it almost feels like these may have a lock-up converter and if so I feel this happens in that lock-up range and could be associated with that. If no lock-up converter, it has to do with the gear change and I'm not sure what gears are in that range, probably 3 and 4 from my experience. I feel its in power management and maybe the system just has a sweet spot for confusion. Just know its pretty damn violent on the transmission and I feel at one of these incidents something will pop. We called a larger local Ford dealer explaining the issue and of course they had never heard of it and "Bring it in" It does not happen if we keep foot out of it, one day I'll get time to hook it up to forscan and maybe see something. If you get any genuine constructive feedback from your dealer DO KEEP US POSTED! THANKS for sharing your common issue!

That sounds pretty much identical to what we experienced a few times now. Oddly enough we were driving in ice and snow last week and the dash told me it had disabled AWD. We own 2 FLEX and my wife wanted this thing,, I can't count how many times I have said "Sure aint a FLEX" I have had more issues with this crap wagon than both FLEX and this is 5 years newer, I would never buy another EDGE I can 100% say that. Of course EDGE was never in the same price tier either, its just a cheap ride, one step above the ESCAPE. Shame they are just not more reliable. Been looking for another FLEX but damn have prices gone up. Need to see what this pile is worth, may be able to break even or close.

Regardless its a decent bit better than what was in my 2010 Flex so at least you have that going for you. Torque seems to be the killer and the torque on my 2010 Eco Flex is not much different than the torque on my 2015 Edge Sport despite the edge being 2.7L vs. 3.5L My Flex has more HP though.

My opinion on the whole driveline is it is pretty much maxed out with the horsepower the V6 ecoboosts put out. I'm hesitant to add any power to them since I hate working on stuff like this. In the 80's when "Mudding" was the thing, you upgraded driveleine FIRST if you were smart. Dana 60's will handle some crap! Not much that I am aware of that can be done to these to drastically upgrade the driveline. The 3.5 Eco can be had @ 450HP in the F-150 but that has a LOT more driveline.

From that text I assume 2016 stuff on uses DA8Z7251C I'll definitely pop my dead 2010 one apart and get some pics. Depending on mood and time I may pop the new one apart to compare.

Found the text of the paper just in case anyone was curious,, The power takeoff unit (PTU) has been a service concern on some PI Utilities. There may be an excessive oil smell when driving, the AWD may not work properly, or the PTU housing may be cracked, leaking or noisy. The cause of the PTU damage is the excessive torque loading of the idler gear, which causes the bearing to walk (move) into the housing. (That is me at this time with my 2010 Eco Flex) In January 2014, a Full Face Thrust Washer, FFTW, was introduced. This new washer was designed to prevent the idler bearing from walking into the aluminum case. In October 2015, a second change was made, in this case a loose-fit idler bearing. In dynamometer tests, this bearing design change showed a twice life improvement over the FFTW design. In June 2016, a third change was made. In this case, a new bearing design, one without drawn cups, was installed. This eliminated the walk mode of damage. Dyno testing shows a three to four times improvement over the FFTW design.

I wasn't getting notifications on this but I "Followed" it now so I think that will fix it. I have a few things ahead of this that need attention, one being putting a new PTU in my Eco Flex, I tore the original up. Not a good idea disabling traction control and giving it hell, Torqued the case and something moved inside, started whining immediately after, wife even picked up on it and gave me the "You Dumb Ass" look ? Now it sounds like a ring and pinion would if backlash was way off. Found a ford article on them, they have updated the PTU about 5-6 times since it started, The one I bought (DA8Z7251C) from Ford is last revision, supposed to hold a decent bit more torque now according to the Ford paper I read. Anyway, get that done and then I'll play with the Edge unless it lays down or starts acting worse Its cool as long as you keep foot out of it. THANKS FOR ALL THE HELP!! Guess Forscan learning curve is in my near future,,,

Its bone stock as far as I know, we bought it this year with around 100k on it, forget the actual number. We bought it from a Ford dealer in New Orleans and had it shipped to Indiana around April, was birthday gift for wife. Its 2015 Sport, not sure there were engine/trans options on it but its the 2.7 EcoBoost AWD 6 speed with paddle shifters They did all service to it at that time and handled a couple recalls so it was fully serviced when it showed up. No complaints with them at all. I checked engine oil and trans fluid when it showed up, both looked new. Did not check PTU but will change the fluid when I do our first oil change. (coming up soon) This issue started in the past couple months. I had looked into "Forscan" and had planned on using that when I get time to dig into it. Is it any good? I had programs for our "Diesel" days with VW TDI and Ford PowerStrokes but have not messed with late model gas engines much. In "Gas" we currently we have 2 -2010 Ford Flex, one turbo one not, this 2015 Edge Sport and a 2001 Sport Trac for a spare.

Been searching but can not find anything on our issue, not sure if common or not. This has happened a few times now, stomp pedal and takes off great then dash goes nuts, trans starts slamming gears and it shuts down dead. Have to roll off road put in park and restart, runs fine after but am generally hesitant to stomp it again. Pretty violent experience and I feel quite dangerous, anyone hear of this before? Any ideas? Normal driving not any issues at all, ONLY when hard acceleration and not always. THANKS for any starting points here!
