Hey! I baught my Sable for $1150 CND, and it's a 1991 3.8L, and it's running strong for me, and I can see the transmission breaking like everyone else's too. How much milage you got on yours? Mine's at like 113000KM when i baught it, now it's like 117000KM.
Wasn't the known problem something about an aluminum part? Well, it's known in material engineering that if a material is weak, it'll only take so many rotations at a certain force to break it, seems like this is the case, no matter how you drive it, after a # of turns it'll break just like parts in the laboratory. Replacing this with a stronger metal will effectively make the # of rotations for failure tend towards infinity, well, like 10^7 at or something like that. So it was inevitable for your transmission to break, was just a question of time. And I hear that if you replace the transmission, it costs a lot, but you can get them to install one that has a steel part instead of aluminum, which would last indefinatly, like transmissions should. But if you're gonna race your car, I don't know what you should do, not get a stock transmission of course, the taurus SHO was made for racing, look into that? maybe you can transfer over a transmission from a SHO if it's good, i think i saw a site talking about that, you just need a few extra things.
Anyways, that's all I can say.
So how long were you driving it until it broke? were you peeling out at lights and racing and stuff? I think if i start doing that mine will break like yours too. So I guess i'll have to hold back.

Hey Guys,
That AXOD has a history. I've smoked a few of them; two on an '89 I bought new in Dec '88. I had 102,000 Mi on it when the first one went and only 35,000 later for the second. Sold it a year later in '94 @ 145,000. In Dec '01 I picked-up my current '92 wagon for $1200 and smoked the tranny in the first week of Feb '02. Since I got the car so cheap, and everything else was in excellent cond., I thought I'd do some serious research on the possability of doing my own rebuild.
I learned a lot!!!  Mods and updates were the big thing I needed to get my arms around. The aluminim piston had a problem of cracking. An extreamly fine "hair-line" crack, but would allow pressure to drop and you'd burn-up from lack of lube. It was updated with a steel pistion but not sure when. Planetary gears had a couple of updates over the years, latest have extra lube holes. Also on the Planetary issue, the internal tubes were rerouted so a larger dia. tube that fed the speedo gear (don't need much) was "crossed-over" to feed the planetary, and vice-versa. A "1-qt over fill" was also put out; intended to raise fluid level to better lube the planets. To improve flow, another mod is to drill two "full-time" flow holes in the valve body. May be others but i don't recall everything.
I added an after market shift kit (looks like a spring and spacer), an aux. trans fluid cooler and AMSOIL Universal ATF; 15 qts includs the 1-qt. over-fill. Runs perfect since I got it back on the road on 1 May '01 and thats been 30,000 miles ago. Moving to Central CA next week and I've gotta do a pound tripper to WV in May (all trips via Las Vegas, NV too). That should give me another 10,000 by the 1st of June. If current performance is any indicator, I should be fine.  |
