GODDAMN transmission problem (now transfer case problem?)

4/28 , 4/29 UPDATE----

The car actually runs perfectly fine w/ no noises when the 4WD is set to "LOW."

Once it's set to "HIGH," the noises come back, AND, reverse no longer works.

Also, after reving the engine over 3k for long periods of time, the overdrive light starts blinking, and the next part I'm not sure if I can explain properly.

The OD light keep blinking, and it seems that OD is off (half way). Usually when I turn off OD, the engine will rev a lot higher. This is expected. And When I turn off OD, it revs lower.

But now that it's blinking, it revs higher, when the OD is percieved to be off, the RPM higher than normal, but not as high when OD is actually off.

or in other words...
While the light is blinking, and I turn off OD (at this point, I can't tell if it's on or off by just looking @ the light... I can only tell if OD is off when the engine is reving higher), the engine revs higher. When I turn if on, it revs lower, but not as low as when the OD light is not blinking.


This goes away after I leave the car overnight.


The mechanic disconnected the transfer case's ability to go into "LOW" and "AUTO" mode, and did something so the geary noises does not come back while under "HIGH" mode.


So, now, is it OK to drive in this type of condition? I doubt it, but oh well. I really need the car for obvious reasons (work..heh).

I essentially lost the transfer case's ability to be in "auto" mode, and it can never go into "low" mode. With this, the car runs just like it did before, except, that on some occasions, when I accelerate, it feels like the car's running on 3rd gear instead of 1st gear (so it accelerates slower than usual).


I fear that when I go to the dealer, they're goign to strip down everything, replace everything, and charge me an incredible amount of money.


sigh 🙁 🙁

------------------



My car is a fvcking money pit. First the engine goes, and now it's fixed. Just bombed 100 bucks on O2 sensors too

The transmission's been serviced, but it's been less than a year since then. Now it's gone again.

It makes a loud, geary noise everytime I let my foot off the accelerator, and it only happens when I go above 40 mph or so. It seems, after the tranmissions goes past 2nd or 3rd gear, and I let my foot off the petal, the loud, geary noise comes on.

I just have to press on the gas to make the noise go away.

Before I look like a total noob in front of the dude who'll fix my transmission, and he tries to rip me off, you guys tell me exactly what's wrong, what needs to be fixed, so he doesn't charge me on uncessary fixes and what not.


EDIT: sorry, not filters, i meant SENSORS.

EDIT2: also, any suggestions as to who I go to for the fix would be appreciated. Do I just go to some tranny mechanic? dealer? etc..

If it makes ya feel any better my '99 taurus is having transmission problems too. I've already taken it to a mechanic but unfortunately he doesn't do transmission work so he couldn't help me. I'm getting tired of sinking money into this car (about $1500 in the last 6 months) so I think I'm just gonna scrap the heap and buy something else. I can't continue to take my car to the mechanic 'cause I really need to have a car for work.

..could be damaged planetary gear assy from broken friction material from the bands. Fords planetary gear sets are trashy.

Might not be the Trans. Sounds liek it could be gear noise from the rear Diff. Jack teh wheels up and spin them and listen to the rear. Also check out the drive shaft and see if it has any play near the diff. input.

 
They probably reused the panetery gearset, and it failed. A buddy of mine (who posts here) had it fail after a rebuild. Reported roughly the same issue as you did; where it went away under power.

Could also be a bad fluid pump.

Generally, that would make noise under load instead of when not loaded. When not under load, the load bearing surface switches from the front of the pinion gear teeth to the back, which wear much less. If this were a breakdown of lubrication, the sound would be more noticable under acceleration, as there is a much higher deflection causing load when under acceleration.

That's not to discount the diff as the issue though. Jack up the explorer and spin the rear wheel. The other should turn in the opposite direction. Check for wierd noises, or a jerky motion which could be a sign of a broken tooth.

While I hope this is true, the noise definitely comes from directly below me (driver seat/center console area)

if that's the case, do I still go to a transmission mechanic? Also, during my last oil change, the mechanic told me that the transfer case had a slight, but pretty negligible leak (wtf? any leak is negligible?). Maybe it got worse, but I've been inspecting the car almost everyday for leaks. The lines are all new, and the car doesn't leak.

What kind of geary noise is it? By that i mean what is this pitch; high or low?

that depends on the speed. If I let go of the pedal at higher speeds, the pitch is high. As I slow down, the noise pitch goes down as well.

Hmm, my knowledge of cars isn't very extensive and i doubt this could be it (since it isn't shifting) but i was thinking of synchronizers.

The sound is originating from the transfer case.

The car actually runs perfectly fine w/ no noises when the 4WD is set to "LOW."

It does come back when in any other mode.


aggh. 🙁
 
od blinking is it telling you there is a trans code in the computer for it. The loss of reverse and high revs forward can be because the trans is in limp mode. Can lose rev or even high gear (hence why the rpms are going up further) till the problem is fixed. Can also be an easy fix or one hell of an expensive one but wont know till you get the code read. Just make sure to bring it in when the od is blinking so it is still stored in the computer. Most of the time when the light goes out the computer resets itself and clears it so its improtant that it is bliking.

Sorry to hear about your expenses. They sound very familiar. I know a couple of people with Explorers and they ALL have major repeated transmission problems. Consumer Reports puts the Explorer transmission/drive train at the worst possible category (overall it gets quite horrible reliability marks too). If I were you, I'd seriously consider selling it before you get another transmission problem.

Ford makes good vehicles. The Explorer is not one of them.
