95 ATX Tranny pboblem only when warm...

[Tecchie]

Okay, here is the lowdown...

95ATX Green w/206k+ on clock... Possible original trans (have only had the car about 8 months now) so I don't know for sure..

Anyways, when cold I can roast the tires from a stop.. Once it's up to operating temp, I can't roast'em anymore..

Trans shifts fine between 1-2 when cold, after warm it is soft between 1-2 then slams the last little bit....

When cold on freeway I can get it to kick down from OD (4th) to 2nd @ 50MPH or less... when warm (operating temp) it kicks down to 3rd from 4th (OD to D) and won't go to 2nd until I manually shift it there or press the OD on/off button...

If I press the OD button for OD to be off, then it will kick down to second gear, but will stay there even with my foot off the gas until I turn OD back on... (light on dash = off)

One other thing is that occasionally the OD light will be on, on the dash indicating that the overdrive is turned off... I can't get the button to work until I shift it into gear and wait a few seconds...


I was told by Bickford Ford around here in Snohomish, WA that it sounded like the trans's internal oil pump...

Another shop that does trans's only said the same thing...

Is there a fix for the pump without ripping the whole mess out of the car?

Or should I just have a new trans installed? and if I have to get a new one, I want one that has all the updates and has been drilled for lubrication...

Any ideas??

I am going to have this car for many more years and miles and eventually will be supercharging her as she'll be one of my daily drivers...

TIA GUYS!!!!

I'm pretty sure the pump can be removed from in the car, but it's not easy. The side pan has to come off. I'd remove the air box and cruise control unit first.

Sounds like a fluid change might help...? How long's it been?

getting that side pan off, is a royal pain in the ass, you have to drop the subframe slightly it's so friggin tight in there.

The tranny has to come out to pull the pump. You CANNOT remove the pump from the side.

Avoid taking advice from someone who has never been inside this thing.

Perform your hydraulic pressure tests instead of guessing. The procedure is in the manual.

A little late, but I agree with Steve. Your symptoms reek of low line pressure, which could have one of several different causes. Furthermore, if the pump needs replaced, you might as well rebuild the tranny while the entire unit is out of the car.

IOW, be prepared to drop some greenback.

Hope all is well.

hey look, you have 1337 posts! sw337.

my trans is starting to do this as well. I is not happy. I'm hoping a fluid change might help... been, er, a while..

Well, the car has a litle over 206,000 miles on it.. IT's my baby, my project car, and wife understands...

The fluid? I have no idea when it was last changed, as the previous owner didn't know either, he got the vehicle from his uncle.... go figure...

I talked to Midas and they said it's probably going to be better to just have it rebuilt...said they wouldn't feel right doing a flush and gasket/filter change to it after I described the problems... and a couple of other tranny shops in town said it sounds like the pump is starved or on its way out...




In either case, how much for a complete rebuild kit with all the updates and parts? would it be cheaper for me to get the parts/fluid and have a trans shop do the rest (I don't have many tools, jacks/cheery picker, etc) or....what am I looking at here? And where can I find a complete rebuild kit with all the updated parts, clutch packs, etc..etc.. ?

I am on a very tight budget, otherwise I would just have a tranny shop do it like right now.. lol

Thanks! Been busy, as usual, but all is well.

You must be more 1337 than I, as I didn't even n0t1c3!

If you are able and intent on rebuilding the tranny yourself, this "How Do I?" thread will help get you started:

Tecchie, if you decide to attempt this yourself, give me a holler if you need a hand. I've never rebuilt an ATX, but I'd like to learn. I've also got a ATSG AXODE/AX4S manual around here some place. It's probably not as good as the Ford manual, but might do the trick.

 

[n8rsk8r]

Also, I will actually be completing that thread very soon. Still trying to locate an a donor trans AX4S (hint.. hint)

EDIT: Don't want to spread mis-information.. until I can confirm the AX4(S)(N) issue for sure. Sorry for any confusion.

 

[projectSHO89]

the 95 will be the AX4N, not AX4S.. just so you know. Also, I will actually be completing that thread very soon. Still trying to locate an AX4N (hint.. hint)

Uh. NO!!!

The 96 will be the AX4N, the 93-95 use the AX4S.

BTDT.

Still driving it 40K miles and 2 1/2 years later.

Actually I believe it's the AX4N (Non-Sequential) on the 95 ATX's... I've noticed that when there is a shifter that shows 1-2-D/OD then when you put it in 2nd gear, you start in second...where as the AX4S (sequential) doesn't offer that... some manuals says putting it in second and starting that way on an ATX (like my wifes contour that we traded for this) calls it the "snow gear" lol

Anyways, you can tell on my non-sho 96 taurui that the shifter is labeled 1-D-OD...... if you put it in drive, you just don't get the OD function... and it's a AX4S..


Also, when you WOT the engine when you are slow enough you can feel the gears cycle backwards on the AX4S to get to the gear like 1st or 2nd.. where as the AX4N will just jump right to the appropriate gear....

That's my $0.02 worth... and yeah, when I get some more tools together and parts I'll be hittin you up for help, bradman, if you don't mind... as long as my case isn't cracked which I don't Think it is, then I'll just get a complete rebuild kit...

 

[hawkeye18]

There never has, never is, and probably never will be an AX4N on a gen 2 SHO. Sorry. I, like many others, wish we had a non-sequential tranny on our beloved 93-95s, but it's not gonna happen.

93-95 trannies are ALL AX4S. AX4Ns were only on 96+. Please don't beat this horse.

I have found different manuals stating 94-5 was AX4N. If it is truly not then I admit I am wrong.. but what I do know is that different transmissions were offered same year for regular taurus/continental/sable.... both in the AX4N and AX4S.


BUT depending on when the SHO was built there are carry over parts that went from year to year. LIKE.. the torque converter/turbine shaft splines. 93 and some in 94 had 23 tooth (F3DP-7902-BA)(36) and some from 94 & then 95 had 25 tooth (F4DP-7902-EA)(42). << those ford part #'s are for the torque converter. On 12/20/93 there was the switch from 23 to the 25 tooth.

I am going to try to put all the dates up that I can for part switches like that in the AXOD-E thread. Hopefully that will help some of us out a bit more I have amassed an impressive amount of Ford 3-ring manuals on our transmissions

 

[projectSHO89]

Check the vehicle cert label on the door for the TR code.

For 95 MY

L=AX4S
X=AX4N

As hawkeye already pointed out, the horse is dead. Quit beating it.

 

[Axianator]

Furthering the point even further...

- AX4S- and AX4N-based computer calibrations are not interchangeable.
- The D4U1 calibration was programmed to control an AX4S transmission.
- All '94-'95 ATX SHOs used the D4U1 computer calibration.

Thus, all '94-'95 ATX SHOs were equipped with an AX4S transmission.

 

[NEp8ntballer]

personally I'd rather pay a couple hundred for a flush to see if that will fix it before dropping over a grand to rebuild the trans.

 

[n8rsk8r]

I understand and understand, I actually misread/mis-understood some articles in the TSB manual..

I have corrected my post.. at this point I am not the one beating the horse..
