I have a 2000 jeep wrangler, just replaced the master clylinder and slave cylinder but i continue to have problems after my jeep sets for awhile, the transmission will not go into gear, if i pump the pedal about 30 times it will shift great while i'm driving..............is there anything else that i need to check...........where is the bleeder on the slave cylinder, i saw on here that it is located on the back of the slave cylinder but on mine this is where the line in attaches and there is no bleeder there, if i feel up on top of the slave cylinder i feel something like an allen screw may be located maybe that is where it's at?...............thanks for any assistance.........already paid a guy 260 bucks to replace the master cylinder and slave cylinder............so now i'm even worried about taking it back and having him mess it up more
The bleeder screw is located on top of the slave cylinder. It will not work right until it is properly bled.If the reservoir runs dry, you will have to start all over. Have an assisstant pump the clutch pedal 3 times with the bleeder screw closed...then hold the pedal down and open the bleeder screw. Don't release the pedal until the screw has been retightened...continue this process untill no air bubbles come out of the bleeder screw....don't let the resevoir run dry...Please rate this...

Check the clutch fluid level. If it's low, add some (takes brake fluid). There is a bleed valve down on the clutch slave cylinder on the bellhousing. Open the bleed valve and have someone push the clutch pedal slowly to floor, and hold. Close the bleed valve, and repeat until fluid comes out in a steady stream when the pedal is depressed. Your pedal should have pressure now, and the clutch should be working. If no fluid is forced out the clutch master cylinder, into the line, and to the slave cylinder when clutch is pressed, then you may have a bad clutch master cylinder. If fluid does come out the bleed valve, but still no pressure on the pedal, it may be a bad slave cylinder. Post back for more. Would like to know what you find out, and what the problem was, OB. Good luck.
Look to make sure your Hydraulic fluid level is full for the clutch. It
is located near the brake master cylinder(see owners manual) . If it
is low , fill it and pump the clutch pedal a few times and see if that
takes care of it. If it doesn't then I would be looking at replacing
the slave cylinder and master slave cylinder for the clutch. If it is
completely empty and you fill it and pump it a few times, and its back
to empty. Yes, you guessed it, look for a leak.
leaky slave or master cylinder - if you have someone listen to the slave cylinder while you press the pedal is should "squelch" if there is air in there, if the slave cylinder doesn't make a squelching sound then the master cylinder or a hydraulic line between the two cylinders is leaking - slave cylinder isn't very expensive but the master cylinder can be rather pricey. and any good parts shop or motor-factor can source or make-up a new hydraulic line if it is the line itself that is leaking.
Check the clutch master cylinder, the line to the slave cylinder on the bellhousing and the slave for leaks. If fluid is low there is a leak. Master can "bypass" as well similar to a brake master in which case it wont leak but the slave won't move when the clutch is applied. If that system is working then the clutch likely has worn out.
If you have an internal slave cylinder check it for leaks or if an external slave cylinder check it for leaks. Check the back side of the master cylinder where it attaches to the firewall and see if the seals are leaking. If so replace the master or rebuild it. Same with the slave cylinder.
This is not a bleeder hole, this is a weep hole like in a water pump to see when there is seepage past the seals.
Bench bleed the system. With the master cyl. line and slave cyl assembled, place the master cylinder in a vise, fill the master cyllinder. actuate the slave cylinder back and forth lower than the master cyl. This will allow the air to escape upwards back into and out of the master cyl.
Once bled the system can be installed.
