Partner’s 2004 Scion xA lots all gears in the manual transmission today. Shifting feels normal, and linkages move properly on the transmission, but everything is neutral. Se describes the moment of failure as such:
“It was dodgy shifting up to highway speed, as if I missed 3rd and didn’t have a problem the second time, but after it broke none of them worked. There was quite the shudder in the shifter. (Vibrated but not visibly) . The clutch felt like it didn’t unclutch in the trying for 5th gear.”
Clutch pedal feels fine to me, but she describes it as “like a playground spring”, so it seems wrong to the person who drives it all the time. Slave cylinder definitely moves out when clutch is depressed, but doesn’t seem to retract fully. I can push the end of the clutch fork and it will retract further, but at no point does it act like it is in gear with the clutch out, and I’m not sure I am getting it to full retraction.
So in order of probability I’m guessing:
1) throwout bearing
2)clutch plate/springs
3)sticking slave cylinder or other hydraulic issue.
4)internal transmission failure.
Does that seem right to people? Any guesses or other diagnosis I can do to narrow it down before I pull the trans?
Also, anyone in Rhode Island have an engine hoist I can borrow? Mine is in CT.

When you say you can push the clutch fork in, do you mean with clutch pedal all the way up the fork can swing down further (ie, engage clutch more)? If so I’d take a stab at bleeding the clutch first.
Also, how is the car driven? Original clutch/how many miles on it?

Could be the throw out bearing. When the clutch in my mom’s Honda failed, the bearing jumped through the clutch splines. The only thing retracting the pedal was the pedal spring. When it went in my truck, there was no resistance. I could still shift without the clutch. The trick was getting it started in first gear then keep it rolling after that. Shifting was a matter of rpm matching.

Sounds like the clutch or throw out may have disintegrated based on the vibration and refusal to go into any gear, but that’s a wild guess.

Seconding an attempt to bleed the clutch. Can cause lots of weird symptoms and all you need is a can of fluid. It’s probably something more serious, but it’s a quick check which rules out a hydraulic leak (lines or in master/slave) if the symptoms remain after the system is bled .

Sometimes a clutch can go out in spectacular fashion, not slowly. My money is on that or throw out bearing, so a clutch job for you either way. I agree with others to bleed to clutch first though just in case.

It was someone’s commute into boston car until she bought it a few years ago, and has been her DD since, with a city commute. It has over 150k and it is probably the original clutch.

Qith the pedal all the way up i can push the end of the fork and force the slave piston further into the cylinder. From the limited pics online of installed xA/xB slave cylinders, it looks like normal postion is even further retracted than i can push it.

Being that it was a former commuter, clutch disc or pressure plate going out wouldn’t be a surprise. TOB is less likely just by the nature of a TOB. Keeping in mind that I haven’t personally seen the issue with my own eyes, it’s still worthwhile to attempt a bleed, as there’s a possibility it is that and it’s a pretty cheap thing to attempt.
Best of luck!

I can’t help feeling like a clutch disc look would make for cool ass rims...

It needs the clutch replaced. The splines on the disc could be stripped off. Throw out bearing or slave would necessarily prevent engagement because in both of those scenarios you would be grinding going into gear. Aka shifting without using the cluth pedal.

Sounds like e ither the clutch is slipping, or internal failure somewhere in the input (I’d guess, as it affects all gears). Put both drive wheels in the air, have helper start car in like 3rd or 4th, and carefully see if you and a 2nd helper can stop the drive wheels (both, because open diff) to check... I suspect it's the clutch and the wheels drive fine with no load.
If it needed to be bled, it would be hard/impossible to get into gear while running, as the clutch wouldn’t be disengaging. If you started it in gear, you’d have limited/no ability to clutch it, and would be stalling it or forcing it into neutral.
If the TOB blew into pieces it'd mimic above, possibly with awful noises. If it locked up, pressing the clutch would drag RPMs down, possibly even stalling it.
