I have a 1992 f150 4.9lt with a manuel 5 speed, and i have a leak in the case of the transmission of clutch fluid. any time i drive it in the past coupple of days after a couple of shifts i will depres the clutch to change gears and it will not go into gear. well my first thought was to check the fluid level under the hood but it was fine. now it will only shift if i pump the clutch to build up the presure. what can i do to fix this problem?? if it is infact the slave cylender than how do i change it without taking the transmission off?

Re: SLAVE CYLINDER ISSUES
I thought the 4.9 has a conventional slave cylinder mounted to the exterior of the bell housing?
I am not sure about the 4.9 but I know the 5.0 has an internal slave cylinder, and unfortunately you must remove the transmission to replace it. The slave cylinder is mounted around the input shaft in a complete circle and there is no other way to remove it. You say your transmission is a 5 speed so I am pretty sure the slave cylinder is an internal one.

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.
You have a leak and you have air in the system. More than likely the slave cylinder is leaking, the slave is a direct acting one and as with all direct acting slave cylinder it is located inside the transmission bell housing on the transmission input shaft collar. The transmission must be removed to replace it.
first check to see if you have any fluid in the clutch master cylinder which is mounted by the firewall on l/h side of car. if fluid is inthere, follow the line/hose to the transmission. this line/hose goes to slave cylinder mounted somewhat on the front/top of trans with 2 bolts. that is the slave. have someone push the clutch as you are watching the slave cylinder for operation. it should move with clutch beeing pressed. if it doesnt move than you have a hydraulic issue/leaking master cylinder. if it moved nicely, tha i would be looking at the clutch.
clutch fluid level droppin means that ur clutch master cylinder is leaking,u can check by looking inside car where pushrod goes thru firewall to see if its wet with brake fluid where rod comes thru wall inside car, a wet ,stained carpet.the other possibility is ur clutch slave cylinder located at side of ur transmission,usually drvr side is leaking fluid.if this is the case u will notice clear brake fluid at the bottom center of ur trans,right where it butts up towards ur engine. anyhow its a good idea to replace both pieces at same time to avoid any further issues with clutch pedal. good luck hope this helps
The clutch is not adjustable,it is a fluid clutch.It has to be a leak,or the slave cylinder,and,or, the master cylinder are bad,It does not have to be leaking to be bad,but it is one of the two.Rate please,thank you.
Of course check fluid first & if low you'll need to determine the cause.
Other than that, it would indicate that either you have a leak between the Clutch master cylinder & the Clutch slave cylinder on the transmission, or, one of those 2 parts is defective.
Check under the clutch pedal on the floorboard to see if you can identify any clutch fluid (same as brake fluid for the most part) around the area below where the clutch rod comes through the firewall. If you do, that means the clutch master cyliinder is leaking.
Next is to go to the transmission & see if you can identify the leak there.
Amazingly, cold weather and bad Clutch Slave Cylinders go hand in hand. Once you find the problem just replace the part, tighten the line, bleed the system & you should be good for a long time.
Do not put oil in this system.It uses brake fluid in the reservoir.If the system doesn't have any fluid in it, there is a leak, and both the clutch master cyl and the clutch slave should be replaced. They both were used the same amount of times, and wear evenly. When you add fluid, the clutch master cyl compresses the fluid down the line/hose into the clutch slave cyl. This depresses the clutch fork/arm and disengages the clutch disc so the input shaft into the transmission stops moving, allowing the trans to be put into gear. LOOK FOR THE FLUID LEAKING TO ISOLATE THE PROBLEM. This is a closed system, and the fluid never gets used, unless there is a leak.
No, your clutch is controlled by a slave cylinder and clutch master cylinder. Check your clutch master cylinders fluid level first, if its high, your clutch is starting to wear down. Next, on the bottom of your transmission there will be an inspection cover, remove and check with a suitable flashlight if the clutch slave cylinder is leaking, if so, replace both clutch master cylinder and cslave cylinder. Stay away from slave cylinders that you have to build yourself such as those at autozone! Bleeding of these components will be required.
