If you have bleed the system and If it will not go into gear with the engine running, the clutch pressure plate may have failed.
yes hydraulic could cause this also the clutch pressure plate could be collapsed
There is no adjustment, it's hydraulic.. If it feels funny, it could have air in the line, a leak, or it may be time for a new clutch..
the slave could be holding pressure, try and open the bleeder valve and connect the line.
To the best of my knowledge, the clutch on this vehicle is hydraulic and does not need to be adjusted manually. If you are having trouble engaging the clutch or shifting you should have your clutch checked to see if it needs to be replaced. I had, what sounds like, the same problem with my clutch. I own a 1995 Saturn SL2 with a hydraulic clutch. I COULD NOT put car into gear, whether the car was running or turned off. It turned out that the hyrdaulic clutch was out of hydraulic fluid. I took it to my mechanic, (I hadn't the slightest clue what could be causing this). He took a look and filled the clutch with hydraulic fluid and said it works just fine now. He said he didn't see a leak, or any indications of a leak. So we will see. But the short of it is, your (hydraulic) clutch may just need hydraulic fluid.
if its hydraulic there could be air in your line. bleed your clutch and refill.
If it will go into gear when the engine is off but not when the engine is running, the clutch is not disengaging. It could be the clutch, possibly warped or put in wrong, or it could be the hydraulic clutch mechanism.
When you let the clutch out all the way, if it continues to slip, it's worn out. A slipping clutch indicates that the clutch wear surface has gone. Plan on replacing the clutch disk, pressure plate, throwout bearing and have the flywheel resurfaced. While it's apart, it wouldn't be a bad idea to replace the clutch master and slave cylinders as well. If the clutch will not release when you press the pedal, it could be a warped clutch disk or pressure plate or a faulty hydraulic clutch system (master cylinder/slave cylinder).
Then you'll have excessive hydraulic pressure, and could damage the hydraulic system.
Check the hydraulic fluid in the clutch master cylinder. It could also be a worn/warped clutch plate or a problem with the cluch hydraulic system.
The clutch will have to be replaced. The pressure plate could possibly be resurfaced but usually it is as cost effective to replace the pressure plate.
Depends on the type of transmission you have. If it's an automatic, check the transmission fluid with the vehicle running to make sure it isn't low. If it's not and the transmission slips you've probably got an internal problem inside the transmission. If it's a manual transmission it could be the hydraulic fluid is low if you have a hydraulic clutch, or it could be the clutch itself. If you've got an older clutch that's not hydraulic, it could be out of adjustment, or the clutch itself is bad.
It could be a warped clutch disk, a faulty pressure plate, poor adjustment or air in the hydraulic clutch line. If it shifts somewhat normal when the engine is off it's a clutch problem.
