so i changed the fluid annnndddd......
 
ok so i went to change the transmission fluid yesterday. I have a 1997 wrangler with 133000 miles, got it a couple weeks ago. i do general maintenance when i get a vehicle for my own satisfaction and i did this because i dont think it had ever been changed. it came out like gray liquid silt. So i filled it back with redline and what do you know my 1st 2nd and reverse no longer work. 1st and second are completely blocked, it will go into reverse but will just click and grind, 3rd 4th and 5th will engage and pull. what the hell did i do?

sman68 09-01-2009 02:08 PM

anyone

empty it again...new fluid...check repeat...though if you havethat much crap in there might need rebuilt or replaced.

Ironman 09-01-2009 02:15 PM

You used Redline? Did you use Redline ATF?

sman68 09-01-2009 02:48 PM

no i used mt 90 i believe i dont have the bottle on me im at work. i did it twice still no go, im leaning towards maybe i knocked something like a pivot pin or something otherwise maybe the tranny is bad.

I hope you removed the right fill hole plug/bolt which is half-way up on the driver's side of the tranny to fill it through. The drain plug is on the passenger side near the front... assuming you have the 4.0L engine and thus the AX-15 transmission.

+1 sounds like you removed a bolt instead of a fill plug...but I've been wrong before.

sman68 09-01-2009 04:07 PM

right under the skid plate its a 15/16th for both, ive done it before on my focus and its pretty much the same areas. wouldnt be a bolt i know the difference, the drain had the magnet that collects the random shavings so i know im right on what i drained

sman68 09-01-2009 05:06 PM

well i talked to a guy at aamco and they said it might be a pivot pin, or that something in the linkage is messed up which is random because i dont know what i could of moved but thats pretty much my only choosed

if the fluid came out with as much metal in it as you described the syncros are gone. i bet what happened is that the old fluid was actually helping now that it was creating more friction than reducing. with the new good fluid the syncros just plain dont work anymore because they are too well lubed. replace it.

sman68 09-02-2009 12:11 AM

yah thats what i was hoping didnt happen, i will find out for sure tomo but im pretty sure the syncros are shot as you stated. :(

350chevrolet 09-02-2009 01:37 PM

at least its a fairly simple and inexpensive job if you do it yourself.

sman68 09-03-2009 12:31 AM

is there a how to here on it?

the same thing happened to me.

sman68 09-03-2009 09:09 AM

pm replied to. yah its frustrating seeing a bad ass looking jeep sit there like a paperweight

I just R n R my Tranny, I have a 97 with an ax-5, not sure what yours is, but it's an easy job, just takes some time to do it. It took me 2 and 1/2 days but I was taking my time. I know people say they can do it in a day and you probably could. I used this site as a guide, it's really good:

What I still don't understand is how this problem occurred if the correct drain and fill bolts were removed and only the gear lube was changed. If I were a betting man, I'd bet there's more to the story of what happened. :confused:

it makes perfect sense. syncros wore down, alot, creating the silt like fluid that came out of it. while the old fluid was in it it was acting as a friction multiplier because of the metal shavings in it and making the syncros work even tho they were almost completely shot. when the new fluid was put in it acted as a friction reducer thus rendering the worn syncros useless and blocking him out of the gears. i bet with enough force it would go into gear but the 1-2 shift while moving would have to be done with double clutching like an old non-synced trans. first and second are the two most commonly used gears and there syncros allways wear first, reverse is also fairly commonly used gear so i could see it wearing too. i wouldnt be supprised if water got in the trans at some point along the way and helped to kill the trans tho. spend some time behind the wheel of an old truck with a crash gearbox and you'll see that you dont really need syncros, but they sure do make life easier.

Similar happend to me with my Impala.

Dang "mine-runner" ran great until I did some preventative maintenance. Transmission gets hot and shifts hard. I am pulling a code on the diagnostics and it happened immediately after the tranny oil got changed.

Good thoughts 350....makes sense to me...

sman68 09-05-2009 06:19 PM

yah come to find out the fluid had never been changed and it is the syncros those things are shot, pretty much just gonna be down for a bit. thanks for the help guys and wish me luck

I would guess water intrusion. Transfer case and differentials?

sublimemaze 09-05-2009 09:36 PM

Reverse has no synchro, sounds like a clutch or linkage problem to me if its grinding into reverse with the clutch in. With the clutch in, the tranny should act exactly the same as it does with the engine turned off. If thats not the case, there is a problem with the clutch not dis engaging.

bpowa 09-05-2009 10:02 PM

it hard to believe that the syncros were held together by the fluid.

Was draining and fill all you did?


Did you try rocking the jeep back and fourth and trying it jam it in gear at the same time?

sman68 09-10-2009 10:14 AM

yes draining and filling is all i did, so its been checked and the tranny is fine, clutch wouldnt be an issue cuz it engages in third fourth and fifth. would not having the skid plate on cause and issue, i took it off and havent put it back on yet, and my tranny guys are thinking that could be it. ill let you know in a few if thats the issue but anyone had that be a fix lol....

whiteyj 09-10-2009 10:25 AM

No skid plate back on as in no rear transmission support???????

sman68 09-10-2009 10:42 AM

......yes

sman68 09-10-2009 10:43 AM

like the skid plate that covers the trans, big, black, deceivingly heavy.

mudslinger150 09-10-2009 10:43 AM

you might want to zip the plate back on, that may be ur issue

Thats the one, if and when that is off you want to throw a jack under your tranny housing so it has some support.
