My wife's has ATX has 202,000 miles on it from the factory. It still shifts well and won't need a rebuild for quite a while.

It's all in how you drive them.

Mine seems to shift well and as I said the car has over 184,000 on it, so I'm hoping to get by using it as my daily driver so I can put less miles on my burban.

My first SHO was a ATX and it ran fine for years with liberal spirited driving. Add the biggest transmission cooler you can find and go at it. It's a cheap and easy "fix" ( not really a fix but a life extender.). and can add some life to your car. When it finally does blow, convert it to a MTX with the help of the good folks at the Shoforum. Search "AXT to MTX swap" for some good reading. When the ATX finally goes, it's nice to know you have options with the car.

My 93 failed at 120000 when, then rebuild and lasted 30000 more then rebuilt again and lasted 40000. (rebuilt by my father who is a ford master tech). I now just have a used trans and has been fine for the last 10000 miles. btw the first time it failed was when a rock made a hole in the pan, second time was the forward clutch piston, and thrid was the input shaft sheared.

I get my information from actual Jeep owners - we take them in on trade every day and virtually every one with over 100k has had the trans rebuilt.


dude drop it alright i own a jeep, know many who have and also a member of the forum you can say what you like i really dont care.

somehow i find it real damn hard to believe you take a jeep everyday on a trade if you did all your lot would be is jeeps.

these actual jeep owners you speak of remind me of people who claim to have owned these 4.6 supercharged taurus SHOs

actual jeep owners are the ones who know how to get dirty and swear to never buy nothing but.

man seems like i must be forgetting these 2 transmission rebuilds i had to of have since mine has over 200k on it.. i mean it has to be it shifts so well and its a jeep...

Hole in the pan doesn't count due to "Force majeure". Forward clutch piston must have been the reused aluminum unit prone to failure and revised by Ford, 1994-95 models have the upgrade. The revised steel one would have solved that issue but not the sheared input shaft. If you kept the car after 3 transmission changes means you are truly a one percenter. You get a SHO patch! There are 4 major things to get done when rebuilding a ATX that I personally know of:

1.) Shift kit with the drill mod for more fluid flow to the sun gear setup.

2.) Fluid dam install. More sun gear **** as I understand it.

3.) High friction clutch packs. I think there is a extra disk that can be added to the pack from a Ford RWD transmission , the model in question presently escapes me. Someone chime in if they know what I'm talking about. My memory is shaky at best.

4.) Weld the Diff pin!!!

Above mods are not in any particular order. Get them all done if you go this route.... that is if your ever need it.

Don't forget the cooler!!

I have a performance built automatic by SHO#7 in my 93'
Not cheap, but it is a blast and I could not be happier. As for the SHO, if I could not drive it with the pedal to the metal,--why have one?

155k on my 93 trans and it shifts great. The first 2 owners took excellent care of the car though and it wasnt abused and i dont abuse the car at all. I wish it was a stick car but oh well was to good of a deal to pass up. I would like to convert it to a stick but alot of work and not enough time and room to do it

Yes! :fit:

Especially if you have to remove and install it yourself.

Compared to my experience with MTX's, I had my first (and probably last) experience with swapping an ATX this weekend. Two of my friends, who both have experience with cars in general and SHO's specifically were kind enough to help me replace a slipping ATX in my daughter's car.

Between the three of us we'd have it done in one day.

After two (long days) we are done, and we all decided that that will be the last time we ever install an ATX transmission into a SHO.

Next ATX I pull from a SHO will get a :boot: and be replaced with the combination of a 5 speed and three pedals inside the car!

(This means you- Kayla and Davis and Sunny!!)

You will have to learn to drive standard, or save your pennies for a repair shop.

my SHO atx lasted until about 230k. My jeep automatic lasted about the same, but i pounded on the SHO and babied the jeep. Just the nature of crappy 90s autotragics.

There is one clear advantage for the ATX......you can still get NEW parts for it!!!

With an MTX, your SOL when it comes to gears, syncros, blocking rings, etc...

How many of you ATX owners have actually tracked your ATX? And I don't mean the drag strips. A real track day or two will show you the weakness of your ATX... fluid boiling. Every year at the convention there's somebody boiling their fluid and ATX's are a minority of the SHO convention drivers.

Every year I have to get off the track early because the O/D off light starts flashing (an indication of fluid over temp).

Then there's the parasitic power loss.

I have a heavily modified ATX. With the right setup they can be great. Fluid temps, fluid type, aftermarket fittings/hoses and correct tuning are the key. I have modified lines/ fittings running to a HUGE cooler with an aftermarket high flow fan on a switch. All monitored with a tranny temp gauge.

I have never seen my tranny rise above 190 degrees. I have been sitting in rush hour traffic on I-95, with the A/C on and 4 people in the car on a 95 degree day. Not even pulling hot laps at the dragstrip.

It can be done right. I hope to prove that with the turbo build.

It's scott writing this BTW

Uh-oh, :eek: I have an '89 MTX w/465K. So what can I do when the tranny needs to be fixed? What are my options? Another or new car is not an option at this point due to a myriad of financial and unemployment issues.
