Sorry to semi-hijack the thread. I'm not terribly familiar to transmissions, but does the synchro have directionality? If the output shaft is free to spin (due to broken axle), why would the synchro care whether or not the car is at idle? The synchro would just spin the output to match the input rather than the normal of vise-versa...

 

I guess that would also be where Rice's LSD question comes in...

 

The output shaft wouldnt be free to spin. The axle joint snapping outside of the transmission would have nothing to do with how the trans functions. The axle would spin just like normal. It would just not be connected to the wheel and there would be alot of grinding while trying to take off.

 

Wouldn't that all depend on how it snapped? If it snapped clean, then what is there to grind? Apparently something is grinding, but if there's not much resistance, then it should spin pretty freely. And when I say that the output shaft is "free to spin" I mean resistance. Obviously it's still connected to the diff. But if it's not connected to the wheel due to breakage then there's no resistance for the synchro to spin it. I'm not sure how else you'd get the vss to register without any wheel motion. I also don't know where the vss is actually connected. I assume it's on the trans output before diff? If that's true, the decoupling must be occurring between the trans output and wheels.

Again, the LSD throws a wrench into this. Unless it's the LSD that snapped.

 

Ya gotta remember the boot. The axle boot will wind up and not allow the axle to spin. Same thing happened to mine. I also have lsd. I thought it was a trans issue but i jacked it up and spin my drivers side wheel and saw that my passenger side didnt move. Everything acted just as normal except the car wouldnt move and the was a grinding noise when i tried to take off. I could not put the car into gear without the clutch while i was idling

 

Does that mean your LSD broke? Did your speedo move as well? For me that's the weird part. If the clutch is bad, but everything between the input shaft and wheels is intact, then why would the speedo move without the wheels moving, unless it's the diff?

I hope I don't sound antagonistic, just trying to understand. I'd like to figure out transmissions better.

 

The only thing that broke was my drivers side axle. Everything else was fine. I didnt really pay attention to my speedo. As soon as i hit the gas and heard grinding i stopped to reduce further damage

 

OK Rice it's past 5. We're curious. Get the car up.

 

Well there is fresh white grease evident all over my driver side axle and the surrounding area. Axle feels solid but i guess im gonna take it out to look at it more closely.

 

Just put the front wheels on jack stands and spin them.

 

Well i ripped out the axle and holding it in the middle, i cant get either end to spin without it. soo

 

Damn

 

Grease on the boot but axle seems okay.,

 

Gotta be clutch i guess

 

Call up KY Clutch.

 

You sure that axle is ok?

Does the output shaft spin with the axle removed?

Put it in 1st then press the clutch and see if the speedo stops. I don't think the clutch is the issue...

 

hmm good idea man i'll have to check! thanks for all the advice, as always guys haha

 

Im not sure where that white grease would be coming from. Axles are filled with black grease

 

Okay started the car in the air and peeped into the tob with the car coasting in gear.

Few things i noticed:

Pass wheel was not spinning
Tob was spinning
When the clutch was pressed in, the mph was 0, when i let off the clutch, whether or not i was in gear the speed would go up a bit and my warnig lights (door ajar, ebrake) would flash.

 

I'm now a spectator. You could say I always was, but i'm officially out of ideas.

 

I still think TOB or clutch or both due to one failing and causing the other to fail.

 

Just wierd if its the clutch, i havent smelt anything as of when it went. And the tob appears to be all there

 

Broken trans.

 

Really? wouldnt i have heard all sorts of crashing noises from it?

 

That is possible but you would think lots of clattering and strange noises from it.
