You might have somebody press the pedal as you get down and check the clutch travel. Might have an adjustment on the clutch arm.
Could have wrong pressure plate, did you match them. I would check the travel first.

SOURCE: 1995 gmc sierra clutch pressure problem

could be wrong here but sure sounds like its out of fluid at the "master cylinder" look near the brake master cylinder for a seperate little container for the clutch. bleeding is tricky because it is small and wants to run out of fluid quick. you have to keep adding each time you bleed. Hope I helped. Thanks

SOURCE: Clutch wont engage

With the hydraulic systems, there is no adjustment. So what pedal travel you have is likely normal for that vehicle.

SOURCE: Poor Braking power- new cylinder-new lines new ABS module -bled

i have ran into this problem , but on earlier gm products---check the local dealership or a well known mechanic shop that has all data and check for bullitains. what i had found out was there was some trucks that gm had installed the wrong power booster . not saying your booster is to blame, but may be a great place to look seeing you replaced abs modules ,master cylinder ect---hope that helped out!!

SOURCE: I replaced the slave cylinder on my 91 G.M.C.

Yes, get a pro-bleeder. They are around $ 75-$90 but well worth it.

Hi- 1995 jeep wrangler 2.5yj- clutch grinding won't go into gear - seems full of fluid but over filled it works good for a few months -does it again- repeated -works good-maybe master slave problem ?


1995 YJ if still stock all that is ONE PART, see FSM quote below.
is the fluid dropping, day by day, week by week???
y/n?
yes, then either the slave or mc are bad.
sometimes both can fail, (rust happens inside and is progressive)
what I do , is this. (if not wanting to change out both)
1: look at the MC, if it done leak down either side of the fire wall
it might be good (dont mean the piston seals good but its not leaking, so if fluid drops , (every week say) the the MC is ok
and for sure the slave leaks.

2: so where is your slave. have you looked,? (swaps happen)
most leak and can not be detected as that leak landed on the road to work.
for sure its just 2 parts, here, you know the clutch is ok.
because it works with fluid in the system and bled.
now ILL PASTE THE FSM words out of a real factory service manual.
they are clear.
FSM words, QUOTE:
CLUTCH HYDRAULIC LINKAGE REMOVAL
The clutch master cylinder, slave cylinder
and connecting line are serviced as an assembly
only.
The linkage components cannot be
overhauled or serviced separately. The cylinders
and connecting line are sealed units. Also
note that removal/installation procedures for
right and left hand drive models are basically
the same. Only master cylinder location is different.
(1) Raise vehicle.
(2) Remove fasteners attaching slave cylinder to
clutch housing.
(3) Remove slave cylinder from clutch housing (Fig.
9).
(4) Disengage clutch fluid line from body clips.
(5) Lower vehicle.
(6) Verify that cap on clutch master cylinder reservoir
is tight. This is necessary to avoid undue spillage
during removal.
(7) Remove clutch master cylinder attaching nuts.
Note that one nut is accessible from engine compartment
and one nut is accessible from under instrument
panel (Figs. 10 and 11).
(8) Remove clip securing clutch master cylinder
push rod to pedal and slide push rod off pedal pin.
(9) Disconnect clutch pedal position switch wires.
(10) If pedal pin is equipped with bushing, inspect
condition of bushing and replace it if worn or damaged.
(11) Remove clutch hydraulic linkage through engine
compartment.

Hydraulic clutch is not disengaging, when put into 1st gear the engine conks out. Replaced the master cylinder and bled the line - still conks out. Do I need too replace the slave cylinder or what?


as per your description problem not clutch since able to start in gear and drive without stall problem sounds more like a fuel delivery not the clutch

My 1999 accord wont shift into gear while its on but will when its off its a 5 speed.


It's your hydraulic clutch system that probably isn't working. When you press the clutch pedal down, it causes the clutch master cylinder to put pressure in the line to the transmission's little "slave cylinder" that operates the clutch inside the transmission bell housing. This disengages the engine from the transmission so you can shift gears. It's probably not putting the slave cylinder to work by hydraulic pressure. The clutch master cylinder is mounted on the firewall, similar to the brake master cylinder, the clutch cylinder has a reservoir and you may need to add brake fluid to it. If it is dry, then you will need the system bled at the slave cylinder by a pro or someone who understands how. Pretty simple, really, just like bleeding brakes. Also the clutch master cylinder can develop internal leaks and this will lead to loss of clutch.

I have a 2000 mazda 323 with a manual transmission. i have already change the clutch kit but the gear is still hard to shift


Check the hydraulic clutch operation. This is a clutch master cylinder with a reservoir on the firewall, and a clutch slave cylinder down on the bell housing of the transmission, with a steel tube running from the master to the slave cylinder. When clutch pedal is depressed, hydraulic fluid (brake fluid) is forced from the master to the slave. The slave cylinder should push out a little plunger that contacts the clutch fork lever-pushing it forward to engage the clutch.
Add brake fluid to the reservoir if needed. Watch the plunger on the slave cylinder: if it moves little, or not enough, try bleeding the slave from the bleeder valve. They are bled just like brakes. If bleeding doesn't help, your clutch master or the slave may need replacing. The master cylinder, like a brake master, has internal seals that hold hydraulic pressure, so force can be applied to the plunger on the slave cylinder.

Hydraulic clutch in a 2001 nissan altima gxe 5 speed manual


Open the hood and look for the clutch master cylinder.
It is smaller than the brake master cylinder, but should be very near it.
The clutch master cylinder is about half the size of the brake master cylinder.
Take the lid off and see if it is full.
If it is empty, the likely problem is the slave cylinder (which is mounted on the transmission at the other end of the brake fluid line), has failed and needs to be replaced.
It will likely not do any good to fill the clutch master cylinder, as you will trap air in the line.
The slave cylinder will need to be replaced, and the line bled to get the air out.
Be blessed.

My 95 ford probe has a hard time going into gear i push the clutch in and try to put it into first i sometimes can but mustly i really gotta force it to go into first and the rest of the gears as well


Sounds like there is likely a master cylinder or slave cylinder leak. These are the two that push the hydraulic fluid to the clutch mechanism and sequentially the slave cylinder after getting the pressure of the forced fluid to it from the master, it forces the rod out of it the move the clutch mechanism so that the clutch engages and disengages the engine/trans.
also check if you have a brake line leak as the brake fluid reservoir shares its fluid with the clutch master cylinder. If enough of the fluid is being drained out of the brake reservoir so that you are pumping air into the clutch slave cylinder, but still have enough in the reservoir to have the brakes working, then you should check that as well. I however think its likely either the clutch master or slave.

My hydrolic clutch has just been repaired all new from master cylender to plate but will not stay bled for more then bout 50 miles what could the problem be


can you see leaking hydraulic fluid anywhere? The principle is very simple The master cylinder behaves like a syringe. You press the clutch pedal and fluid is forced by the master cylinder plunger to the slave cylinder mounted on the side of the gear box. The slave cylinder is like a syringe in reverse so that the fluid pushed into it from the master cylinder causes the plunger to extend into the clutch/flywheel bell housing and engage with the end of the clutch bearing release lever. The slave cylinder has a bleed screw on the top of it to release any air that has got into the system. Ensure that reservoir is full and ensure that a sheet of polythene has not been left under the screwed on cap: sometimes done to prevent excessive fluid loss whilst working on hydraulic systems. Make sure that the hydraulic unions at the master and slave cylinders are nice and tight. make sure all bled points are similarly tight. The only possible remaining places for air ingress (and by default fluid egress) are the cylinder fluid seals on the pistons... get under and look for leaks when you can get a colleague to pump the clutch repeatedly
