Alright, guys. Might have a potentially serious problem here. I seem to remember a few other ATX'ers also having this problem, but I don't recall the cause(s) nor has the search turned up anything useful. I welcome any and all opinions. Here's a brief account of what happened:

I was out driving tonight around 2am on some local 40mph highways. As I came to the red light at one of the usual intersections, I made my stop and waited for it to turn green. As it did, I applied my usual amount of throttle (read: not much) and intended to putt through the intersection. The only problem is that right as the RPMs started to rise, something gave (or broke free) and the car stopped moving. I also had a new, RPM-specific, "belt whining"-type noise when the car was in gear.

I proceeded to put it in neutral, seeing what would happen. The car did go into neutral and the engine seemed unaffected. The whine went away, the engine idled fine, made no strange noises, and would rev freely if I blipped the throttle. I then tried to go into reverse and the had the same results as drive--no movement coupled with the whining noise.

I got out, checked for fluids and didn't see any. Fortunately, I was only a few feet out in the empty intersection and was able to push her back to the crosswalk line. I waited until some very nice officers stopped their patrol car and helped me push the girl into the Autozone parking lot just up the street. That's where my SHO resides now at 3:30am.

That brings me to the question of the hour: what's going on? Forward clutch piston? Something in the shift linkage? As I said, I recall a few accounts similar to this but don't recall the cause.

FWIW, my '95 ATX has 135k on it and is not really abused. The first 100k were gently-used, female-driven miles. I have put 35k miles on her since buying her in Dec '99. Fluid changed at 70k by the original owner and then 100k with Mobil 1 ATF by me. Fluid still looks and smells great 35k later, although I had planned to change it very soon.

Any ideas?

That my friend does not sound good. I would venture to say that the diff is no more. I think the only thing that may save you is if you broke an axle. My first question is when you were in gear and trying to move the car, did the speedometer move? If yes, then check those axles. If not, then you may need a trip to the transmission shop. Good Luck.

did the car continue to roll even though there was no power? does it sound like something is shearing inside the tranny? does it sound at idle in a gear like there are little pieces of tranny being tossed around in there? if so my condolances. my tranny did the same thing when it hit 147k i was going at about 35 and the tranny went to shift into second and never quite found it. the final drive gear collapsed, imploded and shot out throught the bottom of the pan, instanly killing the tranny. doesn't sound like the mortal wound mine recieved, but it's not good at any rate. check the c/v axels first. if that's not it you'll have to open up the tranny casing, i hope it's prettier than mine was...

SHO#7:

I'm honestly not sure if the speedo was moving or not. In addition to being in a major lane of traffic at an intersection, I was so caught off-gaurd by the incident that I didn't even notice. I'll try to check that when I get one of my SHO buds to load her up on the trailer. Do you really think I blew the diff? I know the diffs in either SHO tranny aren't that stellar, but I've never heard of an ATX (especially a '95) blowing one before (??).

DoC-JoneS:

To answer your question, the car would roll in Drive like it was in Neutral. No matter which moving gear I put it in (Drive/Reverse), it would not catch and would just roll freely. I tried revving it upto 2000-2500rpms a few times hoping it would bite but it didn't. The sound itself is a little hard to describe, and while it doesn't sound like shearing or metal parts rattlling around, it does sound like some parts are rubbing against each other when it's in gear. It's not unlike the sound you could get from a loose or slipping belt on a supercharger, and it's coming from the tranny area. The engine seems to be perfectly fine and exhibits no problems. I haven't had a chance to check the fluid level or the CVs yet, but I have some assistance lined up for later today.

I'll let everyone know what I find. In the meantime, if anyone else has *any* ideas or thoughts, please post them. Better to hear a far-out idea than nothing at all. Unless it's the CVs, I'm thinking my tranny guy will be performing a rebuild here soon.

Yes, I have rebuilt Taurus transmissions because the diff went bad. Yes, I have had two in here at the same time for the same junk diff.

However, I have towed cars in that the owner was convinced it needed a transmission, and fixed it with an axle. I will keep my fingers crossed for you. Good Luck.

Well... I drove down to AZ tonight to check on my SHO. I started by jacking her up to check for play in the half-shalfts. No play and both sides were still connected at the wheels and tranny. Did notice that both wheels turned together, but freely, no matter what the gear (except Park). I then lowered her, started her up and let her idle. After the fluid had warmed up, I checked the level. Level was ok (in the middle of the crosshatch area), still pink and didn't smell burned.

At this point, I'm thinking it's an internal tranny problem. Dunno exactly, but I'm going to try to have my tranny guy tow it tomorrow and have a look at it. I'll keep everyone posted on what I find out. Thanks for all the help so far.
