Hello all, Had my MKX in to an independent shop today for an alignment, and they noticed that the trans fluid was pretty dark during the vehicle inspection. I verified it when I got home and noticed the same. I bought it at ~49,000 miles, and it currently has 89k on it. To my knowledge, the fluid hasn’t been changed to this point, and I’m not sure whether I should go with a transmission flush or just a simple drain and fill. I’m finding conflicting answers for the 6F50, so I was wondering if any of you have experience on this front. Any advice is appreciated, thanks!

Hey folks! I know this topic has been raised now and then, here & there. I hope to consolidate the interest in one place, in this thread. I am working through people on another site to help make this happen, and will need volunteers/guinea pigs for test & fitment. Please add a post with a list of aftermarket mods you would like to see available for your Edge/MKX, along with the type of vehicle you have. Additional options for the Ecoboost crowd. I will get this started: 2007 Edge SEL - 3.5L AWD Downpipes with high flow cats (and without for no-testing states) Coilovers Tuner Catback Exhaust System Cold Air Intake Kit Stabilizer Bar for front/rear (tuned to the vehicle)

I apologize if this topic already exists on this forum--please redirect me if needed. Searched but didn't come across one. I have a 2020 Edge ST with 30K miles. Five months ago during a road trip I began to notice a subtle lag/jolt and wood-like 'thunk/knock' when coasting between 10 and 15 MPH and gently pressing the gas to maintain speed (10-15 MPH). Occurred only in this range--low RPM, low speed. As the months have gone by, this issue persisted--I've developed the ability to trigger it consistently--at low speed/RPM. The last few weeks the issue (lag/jolt and thunk/knock) now appears occasionally when rolling to a stop--occurs about a half second before a full stop. Also appears occasionally in the 35 MPH range. I took the ST into a Ford dealership two weeks ago and was referred to their service advisor who was said to have considerable transmission experience. He had the transmission software reset and asked me to drive the car normally for several days and see what develops. Unfortunately, the issue remains. He asked me to bring the car back if things didn't change, so I intend to see him later this week. Anyone have any thoughts/ideas/recommendations? Many Thanks!

Every now and then the transmission will kick out of "o/d off" and cancel cruise control, and the transmission repair light will turn on, so I put it in park, turn it off then back on. I hear a clunk when the motor turns over then it's usually find, may need to repeat the off and on step a few times but it acts normally after that, can't find any mechanic or other online source describing my issue. Thanks

My Ford Edge was built in March 2011 and it's been 10 years and 2 months when the brake booster went out, whereas the brake booster warranty is for 10 years. Ford won't help. I called customer service. Additionally, ever since picking up my Edge from Mark Thomas Ford dealership repair shop for having both catalytic converters and spark plugs replaced, my Edge makes a high pitch whining noise like a turbo would, when exceeding roughly 3k RPMs. Doesn't make the noise when revving it while in park. Some say it could be the main crank bearing, some say other bearings such as water pump or alternator or ac compressor. My thought was transmission. Who knows!? Could "Large Leak Evap Emission" code related? Code P0455 135K miles.

Hello, I was wondering if someone could help me out with locating the transmission line that I should tie into when trying to change out my trans fluid. I searched around the forum, but was unable to find the location and process to do so. I did this with my other vehicle (chevy cruze) and the process was easy, so I was planning to do it for our edge instead of just draining out the trans fluid over and over. Any info would be great. Thank you.

SSM 47398 – 2015-2018 Edge Vehicles – 2.0L EcoBoost With 6F35 Transmission – Rattle Noise From Engine Flex Plate Some 2015-2018 Edge vehicles equipped with a 2.0L EcoBoost and 6F35 transmission may exhibit a rattle noise from the transmission bellhousing area while running. This may be the result of a cracked engine flexplate. When replacing the flexplate, lubricate the torque converter pilot hub with Multi-Purpose Grease XL-5-A (ESB-M1C93- before reassembling. Make sure the transmission locator dowel pins are correctly installed. If the dowel pins were pulled out of the engine block, new dowel pins will need to be installed in the engine block. Failure to do so could result in a repeat repair. Refer to Workshop Manual (WSM), Section 307-01A. Engineering is investigating, monitor OASIS for updates.

Our 2015 Ford Edge recently started a rattle noise when we start the engine. The noise goes away when we start driving and comes back again when we stop in a signal or take turns. We thought something not right. So, we took it to the dealership the next day. What dealership told us they think it's a broken flexplate and they gave me an estimate of 6,000$-8,000$ to fix that issue. The dealer asked Ford if they will cover the repair and Ford said they will only cover 1,450$. The edge has 66,000 miles on it, which is just over 6K miles from there 60,000 miles warranty. I have friends who work at Ford. After talking to them and reading a few other forum articles regarding this issue what I found out it is a very common issue for Ford, which is almost always a manufacturing fault. Ford even recalled certain run time Edge for that exact same issue. I asked my dealer why Ford is not covering all which is basically their manufacturing fault and they asked me to call Ford customer care directly. I just called them and they are basically blabbering the same thing saying we support what dealership recommends. If dealership thinks Ford will cover then Ford will otherwise just keep the receipt in case Ford decided to cover that in future. This is insane!!!!!!!!!!! FORD DOESN'T WANT TO TAKE RESPONSIBILITY OF THEIR OWN FAULT". They expect their customer to spend 5,000$ on a repair just after 4 years. Obviously a crack never happens suddenly. If probably started way before 60K miles. It's only large enough now to create a noise. A flexplate crack means there's something else wrong and ford should take responsibility for that. They can't expect their customer to pay expensive repairs on a new car. Should I take my car to a different dealership or a different repair shop to check? I can't afford 5,000$ repair.

Hello All, I removed the Solenoid and Main Control Valve to replace two sensors. Seven bearings and a piston slipped out from the main control assembly. I can't tell where the seven bearings originated from and which direction the piston fits. Is there a diagram available to show this assembly? Thanks.

I have a 2015 Edge SE with the 3.5L engine, 56k miles. I have an intermittent problem where while driving at operating temperature, the following happens: 1. Transmission slips out of gear. It tries to get back into gear, resulting in lurching. Engine continues to run. 2. The gear indicator in the instrument cluster does not display the gear the shifter is in (see attached pic, note the tach shows the car is running, just no gear indicated.) 3. The rear camera activates. The only solution is to stop the car, put it into park (still without a gear indicator displaying on the instrument cluster), stop the engine and start over. Until recently this has resolved the problem. Most recently, the problem immediately recurred. On the 8th try, it cleared up. No codes captured, no error messages displayed. Have never seen the "Shift-to-park" error since we've owned the car. Been to the dealer twice, but of course they are unable to reproduce. They did confirm that there were no codes of any kind captured. Any suggestions on things to look at? Thanks for the help!

I just purchased a 2019 edge titanium with awd after being the happy owner of a 2011 edge limited. Very happy with the car except when I use the paddle shifters the transmission doesn't shift from 2nd to 3rd even though the display changes numbers. The dealer says it is normal and after my asking why in regular drive mode I see the gears changing they said that in regular mode the transmission shifts from 2nd to 4th skipping 3rd altogether. When I asked why there's a 3rd gear they said that that's what Ford engineers told them. Does anybody else have this issue?

Hi, I have 2008 Lincoln MKX with 136k miles. There is a slipping and jerking in transmission when it changes from 1,2,3 and 4. When I stay at constant speed 30M/h it can be clear and it lets the car to shake a little bit and that always happens. After reaching 60M/h the slipping stopped. In parallel there is a whining or whooshing sound increasing with acceleration over 30M/h and increased with speed (It sounds like airplane engine) I have recently changed the PTU at Ford dealer because of leak issue which costs $1800 but that did not solve the problem. I asked them to check maybe there is a misfire but they did a computer test and no misfire problem appears. The only thing I am thinking about now is to change the TSS and OSS sensors. It will cost me $600 but there is no guarantee that this will fix the problem. Other option is to change the whole transmission unit which will cost $2500 and I do not have budget for that. Please tell me what it could be the problem? Regards,

My 2008 AWD Ford Edge appears to have "sticky" transmission in cold weather only. If car is standing outside in low temperatures for long period, the beginning of the ride is troubled with transmission not willing to shift to second gear revving up the RPMs. After period of a minute or so all resolves. It never happens in warm weather or even if car is standing in garage in winter. Any advice on what could cause that and whether there is is any simple remedy? Thanks for advice.

Well, my topic title says it all. We bought this Edge Titanium less than 3 months ago - used - with 9,800 miles. Very low miles for a 2015. It now has 12,885 miles. Purchased this because we make several Cleveland Clinic trips a year and for us its about a 4 hour drive one way. We wanted something comfortable and dependable to travel in. HAHA! Ill never feel safe in this again. Mechanic said he sees this a lot, however not with such low miles (well, I surely hope not). He went ahead and ordered the parts, however, Ford still has to approve the repair (still under warranty and they better approve it). I wanted a new transmission, but they said they can only fix the faulty parts. So now Im pretty much in debt beyond my eye balls with this car and now with this issue, Im sure it will be reported to Car Fax. What does this mean to me? If and when I trade this beast, I will get screwed on any type of trade in offer. No longer a clean Car Fax. AND Ford will not give me a car to drive for the next 1 1/2 weeks (pretty sure it will be 2 weeks at least). And with another Cleveland Clinic trip almost upon us, I feel doomed. What a way to test new transmission parts better than to drive 8 hours in one day to Cleveland in the middle of January? Maybe Ill lose 1st, 2nd and 4th gear on the trip, woo hoo! Does anyone know if I have any recourse in this situation from the dealer I purchased it from?? Any advice is welcomed and thanks for letting me vent. Oh, did I mention it doesnt go into reverse either?

Sorry if this has been posted, but all I could find in this section was PTU threads, lots of them. Where's the Trans oil dip stick and top-up cap on the 2017 Sport ? My handbook shows to move the air filter intake to the side to access it, but I don't see it on mine. I'm looking at taking advantage of a good deal running on a pack of 12 quarts Motocraft Mercon LV, and will exchange the trans oil with this when I reach 50 or 60K miles. Edit: I found it, tucked away under the coolant hose. It would be best to remove the complete air filter box to access it.

Hi Everyone, I'm hoping someone with a little more knowledge about transmissions and cars in general can help me. For the past few months I've had an issue with 2007 Ford Edge shuddering at around 1500-2500 RPM. I finally took it to my mechanic and he told me he thinks it is the torque converter. He said since it's not that bad and the end result is going to be a transmission rebuild I should leave it until it gets unbearable. I have done some "google" research and came across a few different things. First, should I try a transmission stop slip product? There a re a few and I went to Canadian Tire I picked up Lucas Stop Slip but before I try it I want to find out if there is a better product that I should use instead. Second, I've had this vehicle for 3 years, I drive a lot and it has high milliege 200,000KM + I've never changed the spark plugs. Should I get that done to see if possible a misfire in the engine could be causing my torque converter to act crazy and they probably should be done anyway? I used to do this myself on my older cars but on the Edge it is a lot more difficult then simply changing the plugs and I'm not gonna start taking a part the manifold, I'd rather just pay someone else to do it. Please help, any other possible suggestions would be greatly appreciated. I'd like to prolong the life of my transmission as much as possible. Thanks in advance for any help that may be giving!

Back in 2015, my 2008 Ford Edge had accelerating issues with diagnostic codes:P0715, P0717, P0720. My OSS & TSS speed sensors were replaced, codes cleared, etc. Now in 2017 (just shy of 2 years later) the car is showing delays when shifting into/from R and D. Additionally, the car seems to putter when I drive between 45-60mph. The car only has 85,000miles at 9 years old. My last oil change said the transmission fluid seemed a bit low (since the previous oil change) but nothing concerning or alarming. For all we know everything has been fine, except for the issue in 2015. We are taking it in to a transmission shop to have it looked at before it becomes really bad. Just wanted to see if anyone else out there has had these kinds of issues...and can provide some insight as to costs, etc, so we can brace ourselves.

I have a 2008 Ford Edge, about 83,500 miles. My transmission started to stutter, jerk before shifting. This happens about 40-45 mph and around 60 mph. I took it to the dealer where I bought it. Now 3 vists later and spending $1700 for a new PTO unit and seals. I still have my original problem. It is most noticable when going up an incline. The tranny stutters, jerks, then RPMs climb and speed picks up a little. This is starting to happen more. The dealer does not know what is wrong with my car. Does anyone have any ideas?

2007 Ford Edge SE. Very first, very basic. But it works. Hopefully this will help somebody out there.. I know this has been a frustration of mine for quite some time now. Here's the abridged version. Never worked on cars before - fast learner and attention to detail. 1. Transmission seemed to start slipping; didn't do anything about it until seemed to be persistent/safety concern. 2. Drained Transmission oil (there's a simple drain plug on bottom of transaxle, sticks out) and refilled. Required 10 quarts, though about 1.5 quarts remained from the old fluid, so needed to drain some of the extra to level off correctly. Did NOT see metal flakes in the old (disgustingly black) transmission oil. Smelled burnt, definitely not a lifetime oil, and serious concern for transmission health. Transmission works fine, it just seems the car is getting old and worn and should be handled with more care than previously given (don't drive as a performance car if it ain't designed for it). 3. Week later, car slow to start. By third time starting it that day, won't start and need jump from running vehicle. Battery is only a year old, under warranty got it replaced. THEN, five days later, car SUDDENLY really slow to start.. obvious problem. Don't want to bother auto store with more battery tests, talk to mechanics at Jiffy lube and listen to car.. Diagnosis: - No normal signs of Alternator issues - Starter is turning, probably not the issue, could be though since alternator seems not to be source - Fuel pump likely culprit (but ford put them inside the gas tank, so that's a pain in the ass and unrealistic to fix) Go back to get battery tested, it's completely dead. Considering new option.. 4. Replaced starter. When starting first time, it sounds like the engine has a better grasp and run on itself, though it's still slow to start. Take it back to Auto store, run test, battery dead. That's only 6 days with the new battery. It's now believed that there's likely an electrical issue that's causing the battery to drain. CURRENT DAY.. Through a post on this thread I've determined it's possible to service your own fuel pump, but that the electrical issue may just be the wires feeding into the fuel pump, causing it to slow possibly from corrosion or a blockage of some sort. Learned that you can take out the seats, but it's a sweaty job in TX. 5. Fuel Pump inspection.. HOW TO GET THERE.. a. take out floor in back b. take out smaller rear passenger-side seat first (will need deep socket wrenches and some legit strength, some of those nuts are tight), THEN driver-side rear seat. c. BE SURE TO UNHOOK ELECTRICAL CONNECTORS TO SEATS. d. lift carpet and use regular phillips screw head to open floor to access fuel pump electrical connections.. .. Resuming in the afternoon. I seriously lack in electrical knowledge, but I grew up around people who understood it so I feel confident I can atleast recognize if there's a legit burn or corrosion.

07 Edge 3.5L AWD 127k miles When I have the Edge parked on an incline and shift out of park, the load dissipates and a loud "clunk" is heard as usual when reverse engages. However, this clunk continues to reverberate sometimes until i move off of the incline. It's almost like a tinny rattling sound, like something is bouncing around the front end of the vehicle once the transmission is in gear. The transmission also makes a strange sound in reverse, like a very quiet ticking when backing up an incline.

The 6F50 has some rather problematic Turbine Shaft Speed and Output Shaft Speed sensors. The symptoms are described in the video and what to do when you have a total failure of the the sensors. There will be no prewarning lights. However the transmission will demonstrate symptoms that will tell you of the pending failure. If your 2007 through 2010 has more than 60K miles on it you are in the area of failure from that point on. Here is the video.
