    If you have a slave that is part of the throwout bearing, you know what you need to do....Just hoping there is an easier way? Nope...remove trans.

SOURCE: clutch slave cylinder

Yes, it is located on the passenger's side of the car at the front lower side of the transmission.
You will need the following tools: 12mm and 14mm socket. The slave cylinder could be bolted to the bell housing using either size bolt head.
A 14mm and 17mm open end wrench. The hose to the slave cylinder could be found with either size.
a 10mm combination wrench for the bleeder screw. A small set of vice grip pliers.
Removal and installation instructions for the slave cylinder:
1.Take the small set of vice grip pliers and adjust them to where they just barely close down on the slave cylinder hose. Just enough to pinch off the flow of fluid but not damage the hose.
2. Using the 14mm or 17mm open ended wrench, break the hose loose from the slave cylinder, turning it in a counter clockwise direction. Make sure you have the wrench squarely on the fitting to avoid rounding it off.
3. using either the 12 or 14mm socket, remove the two bolts which hold the slave cylinder to the bell housing.
4. At this point with the slave cylinder lose, have the replacement part near by, make sure you have the copper crush ring with it.
5. Holding the hose, rotate the slave cylinder counter clockwise, spinning it off the hose.
The replacement part should have a small metal rod and rubber cover which retains it to the slave cylinder. Make sure to remove the old copper crush ring and put the new one on the end of the hose. If the part did not come with one, reuse the old one. Spin the new part on the hose and place it back on the bell housing, making sure that the rod fits into the steel linkage which projects out from inside the transmission. There is a shallow hole which the rod should fit in. Holding the part in place, don't try to tighten the hose yet, screw both bolts in by hand and tighten them. Make sure you have them both in before you go tightening anything.
6. Tighten the hose, a good snug pull is all that is needed. you don't have to crank down on the line.
Now you can remove the pliers.
7. At this point you will need the assistance of another person. Have them sit in the car, you top off the clutch master cylinder (the one which has just one resevoir) with DOT 3 brake fluid. See if you can find a small container to catch the fluid in, or just use an oil drain pan. With you stationed under the car with the 10mm wrench on the bleeder screw ready to open it up in a counter clockwise direction, have your friend ready to pump the clutch pedal.
READY?
HAVE THEM PUMP THE PEDAL AND TELL THEM TO "HOLD IT" They should keep the pedal on the floor while you open the bleeder screw up.
Some fluid and air may or may not come out the first time you open the bleeder. Close it and tell them to pump the pedal again. They need to pump the pedal at least 5 times and them tell them to "Hold It" again, holding it to the floor. Don't open the bleeder until they have the pedal to the floor.
Open the bleeder and then close it. Repeat the procedure until you see just fluid and no air coming out.. After the first three times you bleed it, check the clutch master fluid level again. Avoid running the reservoir empty other wise you will be bleeding the cluch for quite a while.
Brake fluid will attack paint so if you spill any on the paint, pour water on it and it will neutralize it. DO NOT GET WATER IN YOUR BRAKE FLUID!!!!
If everything goes well, by the fourth or fifth time you have had them pumped the pedal, you will notice the slave cylinder is pushing the release arm and the person in the car should be feeling a normal clutch pedal along with the "pedal free play" being roughly 1/2 " from the top.
I hope I not only answered your question, but have supplied you all the necessary information should you be up to the task of changing it.

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...

SOURCE: 300Zx will not shift out of 5th gear

Dear javatrader: There are very few solutions to this problem. The fact that you had mentioned 5th & Reverse, tells me that you problem is has two possibilities. Both relate to the same component.
The shift fork for Fifth gear and reverse are the same as well as the hub which the fork fits over.
When you Move the stick shift, it moves one of 3 rails in the transmission of which one is 5th and reverse. The hub is what locks the transmission in gear. The gears are what are referred to as synchromesh. This means that when you shift from gear to gear, it makes it possible to easily make the transition without the gears grinding while the car is in motion. The synchros are in fact, kind of a "BRAKE" for the gears so that when you go to shift into that gear, the synchronizing ring, slows the gear down enough to match the speed of the counter gear allowing it to engage with it, without grinding. As the hub slides into gear, there are spring loaded "KEYS" which are small pieces of steel about 1/2 inch long, 1/4 inch thick and 1/4 inch wide with a little hump in them to push up into a small cavity machined into the hub when it slides over it, thus locking the gear into place until you pull the stick to move it out of place. If a key pops out, it could cause the gear to stick, not allowing you to pull the hub back because the key has popped out at an angle which prohibits the hub from sliding over it.
Another possible senario: The fork is secured to the shift rail with a part called a "Roll pin". If this part shears, the car will be stick in what ever gear it was in at the time the pin sheared. If the pin shears, the stick will still move out of 5th gear position but the transmission won't.
This problem, unfortunately is not one a layman can fix. This is best left to a professional.
Good luck......If you are pleased with my answer, please write in, that you are satisfied with my answer. I am new in this "FIXYA" group and need more people responding to work my way up the ranks.

The clutch slave cylinder is at the throwout bearing. Inside the transmission makes no sense

My 1987 jeep wrangler wont shift into gear...i have replaced the clutch master cyclinder or it may be called the slave cylinder whichever is located near the transmission...what do i do next?


If you have replaced the slave unit, and bled the system, then I'd replace the master cylinder on the firewall and bleed it again.
It seems though that you are a bit week on the diagnostics end...A slave unit is bad only if it is leaking fluid or frozen from non use. A bad master, can either leak externally (usually visible where the rod goes into it on the passenger side of the firewall) or internally bypass causing the slave not to move. The line between them cannot be leaking either or nothing will work. If everything appears to be working but the clutch will not disengage it is possible that the clutch itself is bad.

Clutch pedal has no feel and won't come back up all the way


the slave cylinder is most likely it is part of the throwout bearing on that model so the transmission will have to come out the clutch master should be replaced also as they do not like to be "run" dry and the seals get damaged

Clutch fluid leaking off quickly. The fluid is dripping out of the cover on the front of the transmission. Where/what could the problem be?


The clutch hydraulic control unit cylinder seals have failed. It is inside the bell housing and will need to be replaced.

If you go to this page... then allow pop ups and enlarge the image it is upper right in the picture here:

Here is a parts source.... the cylinder is 3/4 of the way down the page scrolling.

http://www.jeep4x4center.com/jeep-clutch-parts/wrangler-yj/index.htm#cylinders

What ever you do... verify that the part is actually leaking. It could be a leaking line and these are NOT cheap to replace. Jeep finally figured out in 1994 they should once again be using a slaved cylinder.

Thanks for using FixYa.

My car sat for about 5 months in the yard. Clutch and transmission are new rebuilt. Went to move the car clutch went to the floor and stayed there. What can I do?


Sounds like you either need to bleed the clutch slave cylinder, or you need to rebuild or replace the clutch master cylinder and slave cylinder. You might want to check with the shop that replaced the clutch and rebuilt the transmission. It may be covered under their warrantee.
