1 day old SHO and blew ATX, need advice

[David's93SHO]

Hey guys, I will give you the low down, just bought this car, 93 SHO ATX, test drove the car and bought it, ran perfect, the ATX fluid is perfectaly red when I test drove it and now. It shifted fine and on the 2 ocasions that I brought it up to 65MPH(basically 1st to 2nd shift) at WOT it shifted nice and firm. Had to try it out with my friend. Other then that I never bagged on it, I only have had it for one day.

OK this is what happened, at a red light, looked to my left because I was making a right turn on red, just as I turned the wheels it made a bang and the whole car ****** from it, felt it through the seat, I was only doing 5MPH tops during the turn. I was just pulling into the parking lot that links me to my garage.

This is what I have found, jacked the car up, in park position the wheel cannot turn(checked one side at a time), in neutral, they turn nicely with no noise. I grabed the inner CV joint on the passenger side and it is loose where it goes into the transmission but the joint itself is fine. When I put it in drive or reverse, it shifts into gear perfect but it makes a loud noise like splines are slipping on spline, almost like I stripped the splines out. In reverse noticable louder(cant hear the engine run), so basically I shut it down from thier. Other then that the level is up and still nice and red and smells perfect, it honustly sounds to be related in the diff or the drive mechanism.

So this is my question to you guys, what options do I have to beef up the internals, I dont see a reason to replace clutch packs or anything because it shifted fine, but is thier anything for upgrades to beef up these things in the diff section of the ATX, I just wanna fix the broken part because other then this it runs fine.

Like I said, I just bought this car, my last car was a 94ProbeGT, I converted it from a ATX to a MTX, has anyone attempted this on here with an SHO????

Well, I thought I got a good deal on this car, runs perfect, all synthetic oil, new water pump and all, 105,000miles and I bought it for $3400 with new paint, day later......ATX breaks, dont blame the seller though, it was unforscene and he himself when we went for a test drive told me to punch it to test the car out so it was not like he was hiding anything. Thanx guys

Sounds like you popped one of the inner half-shaft CV's out of the tranny. The internal are a much stronger material then the splines on the shaft. Jack her up and take a look at each inner shaft. If it popped out then all you might have to do is pop it back in. If you wore down the splines you will need a new half-shaft. About 50 bucks or s o at AZ.

 

[Jr's Sho]

Does it make the noise when your at a stop and in gear or when your going down the road? It sounds to me like a CV axle popped out. Get under there and investigate further.

 

[David's93SHO]

yes, I have gone underneath the car but I will do so again, Like I said, the cv chaft was in but when I grab it she is loose all over the place.

At a complete, stop it just sonuds like splines spining on splines, Press the breaks, shift into gear, grind grind grind, put in reverse, frind grind grind, but ten times worse yet. The thing is I jacked up both left side and right side by them selves and I cant turn the wheel because it was in park so she must not be the CV shaft.

I will take a look at it again, I will try to give it a **** back inside and if it pops inside I will dissasemble it because to my knowledge it should have a spring clip to hold it.

Whatever the outcome is I will take pics and post for the memory banks on here and future events like this.

Its just I know so little about these cars and last night a learned so much under search but found nothing to my issues.

 

[SHO SPD]

I will agree with all of them, Check the half shaft. maybe even set the front end on jack stands, and put the car in gear and check to see if the wheels are spinning. If they are not, very good chance its just the half shaft.

I think that theres still a chance, with it grinding it may be in there enough to not spin it by hand, but with more torqu to the wheels its enough to make it slip.

 

[David's93SHO]

Could someone please tell me where this half shaft is again, is it on passenger or driver side, the passenger side it is installed into the ATX(the side that is loose in the ATX(cv joint), also found the seal leaking a little, the driver side looks like its mounted into the ATX as well so I will have to crawl underneath again and take a look at it, I just got 20 things on the go all at once so I have not been able to dedecate a whole lot of time to it, right now I'm driving my POS truck again.......crap!!!!

Exactally what I was thinking later on today, going out right now to take another look at it before I call a tow truck

 

[David's93SHO]

Alright, just got back from looking underneath, you guys may not believe me, but thier is no half shaft what so ever, all I see is CV shaft, really long over hang on the ATX, oil pan shaped like an "L", pan says AXOD SHO on the pan, and then another CV shaft, I see no half shaft and on both sides I fallowed each CV shaft into the ATX where I can visable see the ATX seal coming out of the ATX.

I can see where a half shaft maybe, from the driver side it all looks like ATX untill the backside of the engine, then from thier the transmission between the engine and firewall goes round and is about 18 inches long going toward the passenger side where it connects to the CV shaft, so I am at a loss right now.

Getting a tow truck and going to get them to bring it down to my shop and have them take a look at it.

Being that I am a mechanic, I am a mechanic for semi-trucks, somewhat cross referenceing all this to automotive. But I know for a fact and I am not crazy, I cannot find this half shaft.

When it gets into a shop I will take some pics of this and post this, I just dont wanna have people think I dont know what I am talking about....

If you've only had it for a day, I would take it back to the person who sold it to you and have him take care of it.

The CV shaft is the halfshaft. If it is loose something is wrong. It may have popped out but not completely. Also, I am not sure about the atx's, but the mtx's have a hanger bearing on the passenger side that makes a lot of noise when it comes loose. Also, how are the wheel bearings? Does the car move when you put it in gear or just make noise?

The half shafts and CV shafts are one in the same. Technically, the half shaft portion of the CV shaft is the bar portion that connects to the CV joints on each end, but most people just call the whole assembly the half shaft. Each shaft connects to the output shaft on either side of the tranny to the spindles.

Here's a pic of what is commonly referred to as a half shaft:

Are you aware you have the WORST year ATX??? I hope it's the half shaft...My SHO is for sale too! What state did you buy yours for $3,400? Is it in good shape? Just curious. Good luck man!

Yeah, the car is mint, engine runs smooth, no noise what so ever, new paint, red, sunroof, black leather interior, thier is not one burn, or rip in the interior, the car is flawless except for some very minor curbing on the rear rim, new Michelin Z1 tires all around, the car still smells new, 105,000miles on it, A/C works awsome, CD deck and tape works great. The car is absolutly flawless, minus busted ATX.

OK, Yeah, of corse thats thier, on my Probe I had an intermediate shaft or Jack shaft.

Basically I called that a half shaft until some shmuck was ******** on me about calling that a half shaft, he said that this is the CV shaft and the intermidiate shaft was the half shaft AKA, jack shaft, intermidiate shaft, quite obvious that guy was teaching me some poor terminalogy, thanxs for the clairfication.

 

[David's93SHO]

Alright guys, got the car towed to a transmission repair shop, basically they said they never have done a ATX SHO torus before and did'nt know if thier was a difference between the 2, so yeah, I pulled the car out of thier very quickly, another tow bill later I talked to a guy who has done MANY ATX SHO's and MTX SHO's, he was explaining to me the weak links of the ATX, I explained to him what it sounded like and how it happened, he started explaining to me of possible causes and Price quates to fix the Problem, also after the transmission is rebuilt the car will be put on a Dyno to insure the ATX is performing like new, and that the valve body is putting out its correct pressures, and its not the half shaft, he looked at it quickly.

Basically the job will cost $1300-$1600 and comes with a life time warrenty

Decent price if he knows what he is doing. Of course, that is MY opinion.

Car sounds nice. Good luck with it.

Answer me this one question: Does the speedo register when you put the car in gear and give it a LITTLE bit of gas?

Why dump money into a new ATX when the problem might be a half-shaft/CV joint?

 

[sdpatt]

You should be inquiring about legal advice rather than mechanical advice.

It does not register speed
