Ford Explorer Transmission Questions



  • nvbankernvbanker Posts: 7,285
    I have always had trouble with what the dealer told you about not changing old oil on old transmissions, but oddly enough, there always seems to be some anecdotal evidence that it's true. Nevertheless, I would try some of the various TransCure treatments you can buy at a retail auto parts store, one that says, "cures slippage", and see if that helps. If not, you're done for. You'll need a rebuild. Sorry!

    Low gear seems to be out in my 97 Ford explorer. All other gears are working. Any advice on what the problem may be.

    Probably a band has broken, but it's going to need a rebuild to fix it. No other way.

    Are you sure it is a trans problem and not an excessively loud coolant fan,the coolant fan is the cause of thousands of trans complaints
  • No it's not a trans fan. It's making a little ticking noise on the trans. I talked to the ford dealer and they said I shoulnt have change the transmission oil if it wasn't done regularly. The sludge on the transmission was keeping the gears together. I talked to several mechanic and they said the same. But it still doesn't make sense to me why this would happen. I added some Lucas transmission additive and it seems to help. But I really have to warm up the truck and drive it around before I can drive it on the street. This is what has to happen when it's cold. Thank you so much for responding.
  • saludos, vivo en venezuela y tengo una ford explorer eddie bauer V8 2008 con un problema similar, el golpe de la caja, acudi a muchos concesionarios o agencias y siempre me dijeron que ese golpe era normal y ademas que no habia forma de quitarselo hasta que me comunique con FORD de VENEZUELA a traves de su pagina web y en pocos dias me llamaron para enviarme a un taller especifico donde me resolverian el asunto y realmente fue asi, despues de casi 3 años la camioneta definitivamente es otra, les cuento que le reactualizan el soft ware y para ello cuando se le esta cargando, la camioneta debe ser manejada durante al menos 15 minutos en una via totalmente plana sin frenar para que la computadora aprenda a cambiar sin brusquedad y debe ser manejada por un tecnico que tenga oido con el motor para asi acelerarla de manera adecuada y cambie apropiadamente, esto debe hacerlo 3 o 4 veces, en defecto de la via libre y plana, realizan el procedimiento sobre un puente dinamico que solo talleres bien especializados lo tienen. Por ello le recomiendo que se comuniquen con FORD pues seguro le resuelven el asunto.

    The member above lives in Venezuela and has a 2008 Ford Eddie Bauer V8 with a similar problem - the thunking - and he also went to many shops where they told him it was normal and there was no way to fix it. Then he contacted Ford of Venezuela via their website and they called him and send him to a specific shop where, after 3 years of having this problem, he was told that you need retrain the software by driving the truck for at least 15 minutes on a totally flat surface, without braking, so that the computer can learn to change without abruptness. This should be handled by a technician who can hear the motor and ensure that it is accelerating and changing properly. This may have to be done 3-4 times, and in the absence of a free & flat surface, specialized mechanics have equipment to replicate this.

    He highly recommends contacting Ford to resolve this situation.

    I wish that worked, but having had one of these transmissions, I sincerely doubt it. Mine had to be frequently reflashed to resolve the problem, which it would do, only to recur in a few thousand miles. It was leased, so I let it go back, but my friend bought it, and has had the continuing problem. Having owned 8 Explorers, most of them being excellent vehicles, in my opinion, once you get one with a bad transmission, you may as well get rid of it, they seem to be cursed with no long term remedy. I've had two of them, an 04, and an 06.
  • OK, let me preface this with I have 232,000 miles on my Explorer and no complaints or problems (knock on wood). That said, starting a few days ago when I disengage the cruise or let off the gas at over 40 mph it makes a whining sound almost like a gear spinning or turbocharger sounds. If I tap the accelerator it stops. Know it has to be in the transmission or torque converter. Any thougths?
  • nvbankernvbanker Posts: 7,285
    My only thought is, if you have 223,000 on it, it has served you very well. Sounds like my first Explorer, 1994, and my best one. Went 150,000 miles with only one problem. Eventually the shift motor for the 4WD went out.

    But I digress.....
  • Thanks nvbanker! Good info and it is a fix I may attemptmyself. Appears pretty straight forward and I have been playing with cars all my life. You were a great help!
  • Hi everyone! I hope everybody's doing great!

    Can anyone tell me how i can check the transmission fluid pressure on a 2002 Ford Explorer XLT?
    I just found out how complicated it is to put the trani fluid in to this car, so i would like to check the pressure first =)
    I think the fluid is low, but I'm not 100% sure...

    It would be great if somebody could help me, thank you!

    Miss Niki,

    I think you want to check your fluid level? To do this make sure the vehicle is level and at operating temp. . On the transmission pan is a large hex with a smaller plug(may be allen or torx head)inside. Remove the inner plug and fluid should drip out. If it does not add the correct fluid until it does. (refer to manual, I believe its MerconV). To add fluid you will need something to force the fluid against the forces of gravity and through that small hole. This would be beneficial to do this because at this point you can add fluid. To check the pressure you would need an expensive pressure gauge(which you will probably never use again) and be unplugging and plugging an area that might leak, and you can not add fluid at this location. A pressure reading may indicate an extremely low level, but not necessarily the correct operating level.
  • I have a 2005 Mercury Mountaineer which the fuel gauge intermittently reads empty. It is a 4.0 flex fuel model. I have read posts about 2002 models needing wiring kits or flex fuel modules to correct this. Anybody know where to start on this model?
  • nvbankernvbanker Posts: 7,285
    More likely, it's your fuel pump, which has an attached float and provides voltage to the guage. Sometimes, whey they age, the float sticks. More often, they stick up and read full, but it's also possible the float has a leak in it and won't float all the time, and sinks to the bottom. This happens on virtually all cars, by the way, not just these. I'd start with replacing the fuel pump. If you're going to do it yourself, I think you have to drop the tank, and if so, make sure it's empty as possible! They're very heavy full. Good luck.

    "...intermittently reads empty..."

    An open fuel guage sensor would indicate a full, OVER full, tank. A short, less than 30 ohms, would read empty. A "sunk" fuel sensor due to a leaking float would also indicate empty but would not likely be an intermittent situation.

    So the most likely cause is a short, to the chasis, in the wiring between the top of the fuel tank and the instrument.
  • My explorer is doing some really weird things... I hope someone can help! When I first start it, it will rev up to almost the red sometimes it dies sometimes not. When I put it in gear it 'jerks' really hard almost feels like I hit something. When driving it shifts real hard in 1st and 2nd. Another thing, when first driving after it has set overnight or for a few hours, it does this thing like if you were to pump the accelerator while driving... bounces very annoying!!
    Please does anyone know what the heck is going on? Is it just a piece and I should count my losses and look for something else or can it be fixed? Thanks so much!!
  • nvbankernvbanker Posts: 7,285
    If it does it consistently, so you can demostrate it to the shop, it should be fixable, and possibly pretty cheaply. Some component is failing and causing this to happen. It may be easy. I'd give it a try, for sure.

    The hard ones to fix are the ones that rarely do it, and NEVER do it within 1000 feet of the mechanic....
  • Thank you. Im def gonna take it somewhere to have someone look at it! Its just soo annoying!!
  • 2006 Ford Explorer 4.0L. The transmission seems to not shift between 2nd and 3rd for a few minutes. It will drive fine for a while, then it does the slip again and the rpm increases when I give it gas. I wait a few minutes and it drives fine again. It is intermittent. Also, when this happens, the temp gauge will shoot to the top and after about 2 to 5 seconds, come back down to normal. A diagnostic showed a mis-fire on #3 spark plug. I changed the coil pack and plugs 1, 2, & 3. It is still doing this.

    I believe it to be a bad sensor maybe or governor. Thoughts?
