cccerbeus Posted September 4, 2014 Share Posted September 4, 2014 (edited) On further examination, it is possible that the apparent leaks are from the vent on the top of the case, and not a seal.. but working on ramps does not make for great visibility so i cant be sure. because of the fill plug's orientation to the rest of the case, and being partially obstructed internally by a gear, i could not get a tube down into the sump to suck it all out, but after topping it up and taking a 150 mile ride, and using a smaller OD hose, i did manage to pump out about 6ozs and refill again. What came out was black nasty sludge, and the magnet on the plug was caked with material again.. The upshot of all this is that the average fuel economy is up almost 3MPG, and the PTU is still under warranty, so if the leak persists i have some recourse..

svtfiend Posted September 28, 2014 Share Posted September 28, 2014 can you guys sum this up for me? what synthetics are used to replace these? 75-140 in ptu and 75-90 in rear diff? I plan on getting a tranny flush along with a coolant flush around 50k miles. what did you all use to pump out the fluid? i have a mighty vac, seems like this will work? i'm assuming the rear diff has a drain and fill plug? where is the plug on the ptu? thanks for all your help! 0 Quote Link to comment Share on other sites More sharing options...

I used mobil 1 synthetic 75w-140 in both the PTU and rear diff, because i had it, and because it was listed as an alternative to standard fluid in the diff in cases of severe service. The PTU calls for 75-140. i used this pump http://www.tooltopia.com/mityvac-mv7241.aspx There are no drain plugs on the PTU or rear diff but it is simple to stick a hose in through the fill port & pump out most of the fluid from the diff. not so easily doable with the ptu.. Next time i try it i plan to make a suction tube out of metal, fuel or brake line, that i can better control than a floppy hose. The fill plug on the PTU is on the passenger side, accessible, but not easily due to being close to a steel brace. my real plan is to drill and tap the bottom of the case for a plug, but you have to drop the Y pipe to gain unfettered access to the bottom of the PTU and without a lift to work on, its a bit of a PITA.. this album on photo bucket (not mine) shows a lot of pictures of the unit, tear down, and location for the drill and tap to install a drain plug in the PTU http://s159.photobucket.com/user/the_natrix/library/Ford%20Edge%20PTU 0 Quote Link to comment Share on other sites More sharing options...
fusion0389 Posted May 20, 2015 Author Share Posted May 20, 2015 Just thought I would poke my head back into this thread and note that I now have 87,000 miles on the 2012 Ford Fusion Sport AWD that i bought brand new. I have had a total of ZERO issues at all with this car. I have since swapped PTU oil out at every oil change (appx 8-10k) and every time i swap it, its just as nasty as the last time. I have continued to have UOA's completed on this oil whenever I get it swapped and its just as bad. Whatever you do, DONT abide by the fictional lifetime fill designation on anything! Swapping out this fluid is not that bad, even though its messy its still a fairly easy job. As the previous poster mentioned, the PTU uses 75W140 and the Rear Differential uses 80W90. I have been using Amsoil Severe Gear 75W140 in the PTU along with Amsoil Severe Gear 75W90 in the rear differential with no issues. To extract the oil i use the blackstone labs oil sample kit with refridgerator tubing. It makes it easy to get right into the sample container. I've also gotten in the habit of doing a yearly drain and fill of the transmission using Mobil 3309 ATF with excellent UOA results. Currently, Mobil 3309 is the only aftermarket ATF that explicity meets the Ford WSS-M2C924-A specification. This ATF is used exclusively by the Fusion SPORT and only the SPORT because we have different transmissions than the rest of the Fusion lineup. I am getting ready to do another drain and fill on the rear differential, its been a little over 40k since the last time i've changed that. I will report back when i can. 0 Quote Link to comment Share on other sites More sharing options...
cccerbeus Posted November 16, 2015 Share Posted November 16, 2015 just a quick update, I got my dealer to replace the PTU under warranty at 59.600 miles, as they considered it failed. (very pleased with this) Also, both front suspension springs were broken and as a result both front strut assemblies were replaced under my extended warranty 0 Quote Link to comment Share on other sites More sharing options...
