    Hi! Today, after hesitating quite a while and reviewing all the info on this forum I finally went to the dealer. The problem with our car, Ford Expedition 2006, accellerated weird. When you pull up, it would shift from 1 to 2, but not accellerate in 2 and directly shift to 3. So when you pull up hard enough it doesn't matter much, because than the speed/RPM is high enough to continue accellerating further in 3rd gear. But when you pulled up slow/normal it would be difficult to pull up further because the speed/RPM is to low for 3rd gear to really pick it up and continue accelleration. At high speed the car was fine. When slowing down the gear didn't shift down until full stop and you heard a big clunck or sometims some rough noise/grumble slowing down.
    At the dealer the "Transman" joined me with a testdrive and was pretty sure he knew what the problem was: a valve (there are 8 of them) on the bottom part of the transmission should be broken. It would take about 4 hours of labor and $100 on parts to fix it. Well ....ok! When I came back that afternoon it was fixed and we did the testdrive again and it was working fine again. Indeed one valve was broken and he replaced all of them. Costs altogether: $580 incl. tax
    I am kind of happy my car drives normal again and I don't feel like something is falling down from my car (the clunck) when I come to a stop.
  • I recently purchased an 06 Expy King Ranch with 58000 miles. Upon driving to Florida this week, we noticed a hard downshift out of/into overdrive. Went to a dealership, turned off the car, went for a test drive with service manager and nothing. Started driving again, same thing. We took the car out of OD and then the advance trac warning came on and the engine light came on. Now when driving at low speeds it sounds like a plastic playing card is in the spokes of the right front tire. Great. :mad: Any answers out there? I've seen posts that say it is as simple as a reflash or as complicated as a torque converter. We have no shifting problems at low speeds/gears and thankfully we don't seem to have the engine fail issue either. Yet. Thank God the car is CPO.

    I am an owner of a 2006 Expedition with 59,087 miles and just had to replace the tork converter and pump on the transmission. Does this sound right? Thanks Fords!!!!! I also just replace a rear hub assembly. Did I buy a lemon or what? Is it even worth going to Fords and complaining? Something has to give. This cost us almost 2,000 dollars. I just talked to another ownerof a 2008 Expedition. She is replacing her transmission as well. I think there is a problem here?!?!?!? It started out as a thump upon exceloration from a complete stop. thump sounded like it was coming from the rear end of the car though. I know that sound carries so this just blew my mind. I do not think I will own another Ford vehicle again. I am so sad. Why is Ford's the only one who does not offer a bigger warranty? 3yr 36thous. miles. What kind of krap is that? Are they trying to tell us to bewarre of their products? GM and Chrysler all give longer warranties.
  • My transmission is slipping. I checked the fluid and it was way low. What kind and how much should I put in? There was none registering on the dip stick.?
  • The manual should tell you what type to put in, if you don't have one you can download it from the Ford Fleet Services web site. How much depends on how much is missing, you should probably get it in for a complete tranny service and evalaution - sounds to me like there is a bigger problem here than just the need to top it off. You need to find out why it is down so much.
  • I have a 2007 Ford Expedition E.B. 5.4L. We had a big snow storm here (Michigan) yesterday and while was driving into work (4A) my transmission acted like it came out of gear then clunked back into gear. When this happened my check engine light came on and a wrench appeared on the display. I took it to the local dealership and they told me that the air filter housing was open and it was allowing air and water into the transmission. That was there diag. I am a ex mechanic and they said that no trans flush was necessary. I fail to see how the air filter housing has anything to do with the trans. Is there a vent tube or valve on the trans that will allow this to happen? Can anyone here give me a reasonable answer?
  • i see its been a while since you posted it and am new to this but my expedition is doing the same exact thing as yours could you tell me what was wrong with your vehicle? thanks
  • The term "sunshell" your being told about or may have heard is probably what is really called a sun gear. A sun gear is a part of the mechanical set-up in an automatic transmission called the planetary gear set. Gears spin and rotate around the sun gear, thus giving it the terms sun gear and planetary gears. Automatic transmissions have from 1 to possibly 3 or more planetary gear sets, depending on how many forward and/or reverse gears the transmission has. In your vehicles case, it probably has 2 planetary gear sets in the transmission. It is possible that a mechanical defect in the transmission (planetary gear set) could cause a clunking noise due to the amount of high weight and stresses the transmission undergoes. If the planetary gear set is the cause of the noise, and it was confirmed with a good diagnosis and repaired properly, the noise should be gone. Otherwise, there is most likely something else wrong with the vehicle and another proper diagnosis should be performed to see what is really wrong with the vehicle.

    Our 99 is not running all that well. This morning it seemed to be ok, but my wife just took it out to go shopping. The spedometer is way up past our actual speed and the 4x4 won't engage. Any ideas? Do we need a new tranny or is it in the transfer case?

    Good Morning, I recently had a transmission colling line rust through while driving my truck. It started to slip while in drive, I pulled over and found the problem but I made a mistake and put a quart of Dextron III in for replacement. It continued to slip while I drove it home which was about 5 miles. I found the broken line and replaced both as the other cracked as O was putting in the broken one. I drained all fluid from TQ converter and pan with Mercron V and now it will only shift into reverse. What would be the next step in repair for this vehicle? Any advice would be appreciated, I am capable of most any repair work but have not rebuilt a transmission before, only replaced one on a RWD Volvo.
    Thanks so much, Noel

    I have a 2006 Expedition Limited with about 116,000 miles on it. When coasting at about 45 mph, only giving enough gas to maintain 45 mph, the transmission makes a clunking sound until accelerate to a higher speed. When I accelerate, there is more intense clunking until I accelerate out of it. The clunking only happens when there is little load on the transmission when coasting. Othen than this, the transmission is fine.

    Is this a sign of something more serious to come?

    I have exactly the same problem. It never happens in lower gears, but I have had it happen at higher speeds when there is no load and I increase the gas just slightly. It seems to be an "overdrive" issue. If I gas it aggressively, it will downshift with no problem. Let me know if you hear anything, and I'll do the same.
  • I have a 2006 ford expedition eddie bauer and when taking off it feels like it is missing a gear, then when slowing down it downshifts hard. I have replaced the spark plugs, changed the oil and filter, replaced the transmission oil filter since it has 60k miles on it. This was the original filter because the dipstick plug was still in the pan when I dropped it. I put the correct transmission fluid per the man. specifications. I cannot see the transmission going bad with only 60k miles on it. Is there some kind of sensor or vacuum line that I can check?

    Hello!! I just bought a 2007 Expediton EL 4x4 in January 2011. I am now having the same issues that you have in this post. Have you found anything else out about this? What was the issue?
  • I have the same problem on my 2005 XLT. At 40-45 it shudders, if I force it to downshift then it moves into the next gear as expected. Also, drove with overdrive turned off and problem goes away, so makes me think its something to do with the overdrive.

    Each year as it gets hot I notice that my Expy runs very hard and sluggish. It is almost as if the truck was switched into 4Xlow (exaggerated) and it sounds like a large commercial truck in terms of engine rev and noise. Very noticeable difference from winter experience.

    In the winter, no problem, the truck is normal. Having the AC on/off does not influence the problem and the temp gauge indicates no difference in temp from summer running or winter. Always runs smack in the middle of temp gauge.

    I live in AZ so it does get very hot here but it just seems the vehicle is working so much harder than it has to. Any ideas if this may be related to the tranny?
  • Hi There,

    I'm having the exact same problem that a few people already described in the post. I have a 2004 Expedition XLT with 128,000 miles on it and just started to experience this problem as well. Like everyone else, seems to only be happening in Overdrive. Please let me know if you've found any info about the problem and how to fix it. Thanks.

    My brother, who drives a 2006 Super Crew and had the same problem, suggested I take my Expedition to Autozone and have them check the ignition coil packs. One or two of them could be misfiring. This translates into clunking and jerking when accelerating.

    I plan to to take it to Autozone and have them check my coil packs for free when I have the time. They also, apparrently have them for half the price of the dealer.

    Thanks :sick:
