Ford Expedition Transmission Problems

1235789

Comments

  • Truck bought new and only have 14,000 miles. The other day after a trip of about 400 miles, noticed a slight scraping noise from underneath when accelerating usually below 30 mph.

    Only does it for split second and don't notice any slippage, just the odd noise. Doesn't do it every time so dealer probably won't be able to replicate.

    Any ideas before we take it to dealer?

    Figure out how to make it 'scrape' consistently. Then take the service rep on a test drive. It's not normal. There is a TSB for a sqawk noise on hard accleration at around 30mph, but it sounds like a belt slipping, not scrapping. Could be related though. Here is the info for that.

  • after using my 4x4 in reverse I switched it over to 2wd but it will not go back to 2wd instead it is still in 4wd, it is driveable but when you release the gas pedal the rpms go to idle no matter how fast you are traveling, help thanks
  • Actually it may not be driveable. If it is stuck in 4WD and you make tight corners on dry pavement you are risking damage to the drive line. Sounds to me like the transfer case shift motor didn't move out of 4WD.
  • I'm having a delayed shift from 1st to 2nd (Slips into neutral) on my 03 Expedition 5.4L 4x4. Just took it to my repair shop today and nothing shows on the codes and obviously it won't act up for mechanic. (Intermittent issue). He mentioned it may have to be reflashed at a Ford Dealership. How much did your reflash cost?

    Thank you,

  • I have a 2008 5.7 L (Big V8) 4 wheel drive Ford Expedition with 21,000 miles on it. In the past 4 weeks it has started having a hard downshift as you slow to a stop. It feels like it is the final shift down to 1st gear but it may be 2nd. It always happens before you stop. There not any type of surge or acceleration. I am just worried as to when the thing is going to break and how do I fix the problem. If any of you have experienced this problem please respond. Thanks in advance for your help.

    :confuse: :sick: :lemon:
  • The first problem is that you have the only 5.7L ever put in an Expedition. Based on the age and mileage, you are still under warranty, no?? I am no tranny pro, but I'd think more of the torque converter than the tranny.
  • AlwaysFord

    Thanks for the reply and you are of course are right on the engine size. 50 years ago I would have that burnned into my brain. I built dragsters back then, But that time and extreme interest in cars has long pasted.

    So you think the torque converter may be the issue. To me that sounds better than the transmission. Since the torque converters performance is very involved with the fluid in the transmission do you think changeing the fluid and filters would help the situation?

    The truck is in warranty but I am always supicious of the parts changers at the dealers. I shoot 1000 yard rifle competition with 2 master auto mechanics. We end up on long drives together to the matches. They share many stories with me about the happenings in their shops. Unfortunatly they aren't Ford guys and the thing is in warranty. I will ask them about it but my son suggested I try here first. He said I might find someone who has actually fixed the same problem and maybe I have.

    Please share more of your knowledge. If it is the torque converter what do you think is happening. And if you had the car and that wasn't the problem what would be your hit list of things to look at next. I want to be a smart as I can before I take it to the dealer.

    There is a TSB for the hard downshift. It is TSB 082207. This will cure it. Mine was so bad it was like a sledge hammer being slammed against the frame at every stop. It will get worse if not fixed. The TSB reflashes the TCM.

    DRIVELINE BUMP WHILE BRAKING - BELOW 10 MPH (16 KM/H)
    FORD:
    2007-2008 Expedition

    This article supersedes TSB 08-4-13 to update the Issue, Service Procedure and remove the production fix date.
    ISSUE
    Some 2007-2008 Expedition vehicles may exhibit a bump feeling while braking to a stop below 10 MPH (16 Km/h). This procedure will improve the bump felt while braking to a stop.

    ACTION
    Follow the Service Procedure steps to correct the condition.

    SERVICE PROCEDURE
    CAUTION APPLYING THIS PROCEDURE TO UNITS THAT DO NOT EXHIBIT THE COASTDOWN BUMP MAY RESULT IN WORSE SHIFT QUALITY.

    NOTE DO NOT ATTEMPT TO REPLACE THE MECHATRONIC UNIT. MECHATRONIC REPAIR/REPLACEMENT IS NOT AUTHORIZED FOR THIS ISSUE.

    1. Install Integrated Diagnostic System/Portable Diagnostic Software (IDS/PDS) or equivalent and ID the vehicle.

    2. Update the Power Control Module/Transmission Control Module (PCM/TCM) calibration using IDS release 57.8 and higher or 58.1 and higher. This new calibration is not included in the VCM 2008.9 DVD. Calibration files may also be obtained at the website. Since the TCM cannot be independently reprogrammed, reprogram the PCM to ensure that engine and transmission calibrations are updated to the latest level simultaneously.

    a. Verify that the TCM shows 8L1P-7J104-AC (8L1P-7J104-BC for 2008 vehicles built after 12/3/2007) part number after reprogramming is complete.

    b. Select the following from IDS, Tool Box, Powertrain, OBD Test Modes, Mode Level 9 Vehicle info, TCM Cal Part Number.

    3. Clear TCM keep alive memory (KAM) and adaptive tables.

    a. Using IDS:

    (1) Open Toolbox.

    (2) Choose Powertrain.

    (3) Choose Reset KAM.

    (4) Then Choose TCM.

    b. Using PDS:

    (1) Choose all Tests and Calibrations.

    (2) Scroll down the menu and choose reset TCM KAM.

    NOTE FOR PDS, RESET TCM KAM IS NOT THE SAME AS CLEAR TRANSMISSION ADAPTIVE TABLES, WHICH IS UNDER THE POWERTRAIN - TRANSMISSION MENU TREE.

    NOTE UNHOOKING THE BATTERY WILL NOT CLEAR THE TCM KAM.

    NOTE DO NOT CLEAR THE PCM KAM.

    4. Verify that the transmission fluid temperature (TFT) PID is above 175 °F (80 °C). If it is not at 175 °F (80 °C), drive unit approximately 3 miles (5 Km) to reach temperature.

    NOTE TFT MUST BE AT 175 °F (80 °C) OR ABOVE BEFORE PROCEEDING TO STEP 5.

    5. Drive unit to perform adaptive shift strategy learn:

    a. Accelerate from rest with light throttle to 15 MPH (24 Km/h), remove foot from accelerator pedal.

    b. Brake very gently to a complete stop (allow at least six (6) seconds).

    c. Repeat Steps (a-b) a total of five (5) times in the dealership parking lot or similar setting.

    d. Accelerate from rest with light throttle ensuring that the 1-2, 2-3 and 3-4 shifts occur at engine speeds between 1300-1800 RPM.

    e. Continue to accelerate until you achieve 50 MPH (80 Km/h) or the 5-6 upshift.

    f. Brake gently to a complete stop and hold foot on brake for at least 10 seconds.

    g. Repeat steps (e-f) three (3) times.

    NOTE THE HARSH BUMP FELT WHILE BRAKING TO A STOP WILL BE IMPROVED. HOWEVER, SEVERAL DAYS OF DRIVING ARE REQUIRED FOR THE TRANSMISSION TO FULLY ADAPT.

  • The service interval for the tranny is 30k. I don't think a premature change would hurt, but there must still be some underlying issue. It would stink to do a premature service and mask the problem only to have it fail outside of the warranty another 20k from now. It could also just be a computer issue and a reflash would correct it.
  • I have a 2000 eb expedition every time I start from a completely stop the truck makes a very hard shift from 1st to 2nd. Any ideas?
  • Yes - take the truck to the Ford dealer and have them reflash the transmission memory. They can do it while you wait or they did mine. It is a 2008. It fix a really hard shift problem.
  • I have a 2007 Expedition with 53,000 miles that I bought used so I had the transmission fluid changed. After driving for a while I noticed when taking off from a stop it accelerates slowly then the transmission grabs and acceleration increases. It feels like either the torque converter is slipping or the transmission isn't downshifting from 2nd to 1st until you accelerate away from a stop. I've seen several messages that indicate shift problems can be fixed by taking it to a dealer for a reflash. Is that the recommended solution for this problem?
  • Yes

    Ford told me that the transmissions work fine and are durable. What messes up is the communications between all of the systems in the drivetrain and the transmission. The transmission learns how you drive and adjusts it shift pattern to your style or the terrain you drive on. So if it gets confusing inputs it starts shifting strange/funny/weird.

    My problem started after a serious 4 wheel experience when I unexpectedly got into off road wet conditions . I was having to clean the mud out of the tire tread by keeping the tire speed above 40 mph while going about 5 mph. There was much stopping and starting. After that the transmission jerked.

    They re flashed it in a few minutes and you would think it was a new car.
  • The tranny is a 4R100 which is used in the F250. There isn't much you can do in an Expedition that even comes close to what it is designed to handle.
  • I have a 2005 Ford Expedition Eddie Bauer edition. Love it, it's been great (I've been driving Fords for 32 years). It had a rebuilt Ford-certified tranny put in it 2 months ago due to an accident which blew out the original transmission.

    I parked it today to run in and get a taco. Engine was on, as my son was in the car with the a/c on, listening to music. After sitting there for five minutes, it suddenly started to move, and it rolled into another car! Damage was minor, but I'm wondering was this my fault and I merely thought I put it into "park" or could it have shifted into drive somehow? Do these transmission ever shift by themselves with the engine on?

    I appreciate any help any anyone can offer. To say I'm upset is an understatement--because I don't know if I had a lapse in brain power or if my car is safe. Comments?
  • Report this to the National Highway Safety people. If they get other complaints, it could lead to a recall. Ford did have a problem like this with their passenger cars back maybe in the 1970s. This government agency is in the spotlight now for not handling Toyota's problems better, and they won't want to get behind the curve again.
  • we are having this exact problem. our expedition has begun hesitating and i am finding it hard to accelerate. we dont have too much of a problem getting to 40 mph. but as soon as we want to go 50 or above or into 3rd gear our suv seems to have such a hard time getting there. can you tell me what the problem was for your expedition?

    my husband just changed the fuel filter and tested the fuel pump. all is fine there.

    thank you in advance for your time.
  • How many miles on it? Have you done a tranny service? The interval is 30k.
  • we are at 98,000 miles. we have never had it serviced yet. but we haven't had it too long either. any suggestiosn as to what it may be?
  • The fluid breaks down over time, which is why they have service intervals. There is also a filter in the pan that needs to be cleaned / changed. I would ask a Ford dealer to pull the records on it and see what has been done. You may get lucky and the previous owner may have had it serviced by a dealer. Or you may strike out. Can't tell until you try. In any event, I would take it to a dealer and have them do the trans service. Better done at adelaer because they power flush the lines and get all the old fluid out.
  • Sorry for my bad spelling at the end there....one other way to tell if it has ever been serviced is by the presence of a rubber plug in the bottom of the pan. It is assembled with a plug in one of the holes (dip stick hole maybe?) and during final assembly the plug is pushed out of the hole and drops into the pan. If it is in there, then it has never been serviced.

    Guys, I bought this car January 2010. 2 months after I noticed car having several "jolts" before it comes to a full stop. Went to the dealer, i was told they need to chexk transmission. Anybody had this kind of problem before? thanx
  • The dude answered you in the other forum before you posted this, I'd say he is pretty spot on with what you described and since there is a TSB it deosn't sound like it is too mysterious.
  • Just received word from Ford that they will not honor damages and transmission from a similar incident which happened to my family. Our 2008 King Ranch jumped and rolled from park into reverse while running. Thankful that no one was injured. Ford road assistance sent a tow company to take vehicle in to dealer ship and it happened to the tow driver also.

    We had transmission problems in June 2009 and the dealership "fixed" it under warranty, funny now that there is body damage and we are close to end of warranty they are washing their hands. The pros from Ford have never contacted me, my wife, or the tow driver to get our information either. It ain't over!

    Call your insurance company and tell them what happened. They may go after Ford.

    I started having the exact same problem today. I have a 2007 Expedition EL and I'm the only owner. I had the transmission fluid service done at 30K (albeit not by the dealer) and 58K (by the dealer). I'm now at slightly more than 60K and this morning I noticed that my transmission was really sluggish going from a stop into accelerating or going from Neutral into Drive. It's fine in reverse though. Then a few minutes after that, my transmission start "sticking" at about 40 MPH and I'm afraid to drive my car faster than that. I pushed it to 45 MPH and the gear didn't change over from maybe 3rd gear to 4th gear? And my RPM is stuck at 3000, will go to close to 4000 if I push to 45MPH. I drove straight home and called the dealer. The service rep told me it sounded like a coil needed to be replaced. He said there are 8 coils and if one goes bad, you get the exact symptoms I described. I have an appointment to take it in in the morning and they said it would need to stay there all day. I forgot to ask for a price range for that type of repair.

    Reading the previous posts on this forum, I also realize that the slight bump that I get sometimes switching from Neutral to Drive wasn't just my bad driving, it might be part of the problem? This was very intermittent and it started several weeks ago. I just didn't think much of it.

    The only warning signal I have been getting is the Low Tire Pressure Warning because I'm missing a TPMS and I'm not paying over $300 to get it replaced so I just override it all the time. I don't ever tow anything.

    I can't find any information about "coils". Can anyone confirm that I'm not just being told a B.S. story because I'm a woman and if you had a similar problem and got it fixed, how much did it cost you? I still have 2 years of payments on the car! Grrrr.

    good morning .... i am sorry to hear you are having problems ... have you recently had mis fires on your coil pack? that was our first issue of many to follow .... you have 8 coils under your hood that ignite your engine and keep it running ... when those coils misfire your vehicle will have the problems you described .... we had 4 of our coils misfire (go bad) and they were approximately $50.00ea and my husband was able to do them himself .... we had a check engine light eventually come on and it told us which coils were misfiring so we only had the change the ones we knew were bad ...

    then no too long after that happened our catalytic converters needed to be replaced {the isues you are having now are similar to what your describing - our suv didnt wanna go it has no power at all and took forever to get to 40mph} on both the drive and passenger side which is a pretty penny ... we were told this normally occurs due to the coil packs misfiring .....

    good luck ... from researching on the web it seems like these issues are issues many people face who own an expedition .... i hope what we have endured helps you diagnose your issues much quicker than what we endured ....

    Your issue does not sound like a coil pack problem. Coil packs generally will give you a check engine light, especially if it is as extreme as what you say it is doing. Coil packs are usually good for 100k or more, over time the boots will degrade and the spark will arc to the motor rather than to the plug which is what will effect performance. There are thresholds for what will set a CEL message, and intermittant misfire may not do that, but if they scan the computer it will show what it is storing. An autoparts store will scan that for free so you should be able to double check. Your problem sounds more like a torque converter or transmission problem as you suggest. The fix could also be as a simple as a reflash of the control module for the transmission. I believe there is a TSB for a reflash concerning the bump you describe.

    BTW, A coil pack from the dealer will run you around $90, from an auto parts store around $50, and on ebay you can find a set of 8 for $90. Other users in boards I follow have reported great results with the ebay purchases.
