Why is there clutch fluid dripping inside the cab?

Keep pumping clutch and bleeding

Open the bleed screw and pump all the fluid out of the system . Refill with metholated spirits and repeat the operation until it is also bled out . Fill with new fluid and bleed out till the reservoir is almost empty . Refill the reservoir.

If you look at the drivers side of the brake fluid reservoir you should see a rubber hose that feeds to the clutch master cylinder. The clutch master cylinder is kept full via the brake fluid reservoir.

Sounds like the clutch slave might be the issue. You should be able to find it on the front of the transmission. Peal back the rubber boot and see if brake fluid drips out. If there is fluid behind the boot than it is leaking. You can also look up under the dash to see it the clutch master is leaking. It will leave a brake fluid trail from where the metal rod goes in. If either of those are leaking than your clutch fluid reservoir is likely empty. You can find it under the hood just to the drivers side of the brake fluid reservoir. After you have replaced the leaking parts fill the reservoir with new brake fluid and bleed the system. Make sure you keep the reservoir full while you are bleeding. You should be back in business when you are done!

remove the slave cylinder and replace. fill the clutch reservoir with dot 3 brake fluis and open the bleeder on the slave cylinder until fluid starts to run out. refill the reservoir with fluid and with the help of a friend have them push down on the clutch pedal and open the bleeder. repeat this step till no bubbles come out and keep filling the reservoir. hope this helps

sounds like the master cylinder reservoir is empty of fluid. re-fill with fluid and bleed all air out of system all the way to the slave cylinder,,, this will / should restore the system.
also,, check to make sure there is not fluid dripping from under the truck when you press in on the clutch pedal ( could be a leak or bad slave cylinder (?) ),, but I would say that the system just needs to be bled.

Is the clutch fluid reservoir empty? If so you have a leak as the fluid will not appreciably go down even with years of use. Check around the foot well inside the car and around the reservoir tank for signs of fluid loss. If the foot well carpet is soaked it is likely the master cylinder seal needs replacing. If the area around the reservoir is wet then the union from the reservoir or to the pipe connected to the slave cylinder needs to be tightened from the reservoir. If there is no sign of a leak then the leak is associated with the clutch slave cylinder, either at the pipe union, the bleed nipple or the cylinder seal. The first two will be obvious to identify on the cylinder itself. The seal leak may well be indicated by drips coming from the junction between the gear box bell housing and the engine block. The slave clutch can usually be refurbished with a repair kit that includes a new seal. Take care when removing the clutch fluid feed pipe not to bend or damage it so that it can be easily re-used when reinstalling the salve cylinder.

check the fluid level in the clutch reservoir,make sure its full,the hydraulic slave cylinder is located inside the bell housing you can check that by looking around bottom of transmission for fluid leak,these systems are hard to bleed air from ,

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 - Transmission/Transaxle). This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort.
Verify that all the lines and fittings are dry and secure.
Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system.
Remove the reservoir cap.
Fill the reservoir to the proper level with the required fluid.
Attach the J 43485 (Adapter) to the J 35555 (Mity Vac), or equivalent.
Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use.
Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening.
Apply a vacuum of 51-68 kPa (15-20 hg) and remove the adapter.
Refill the reservoir to the proper level.
Repeat Steps 6 and 7.
If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops.
The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear.
Pump the clutch pedal until firm (to refill actuator cylinder).
Add additional fluid if needed.
Test drive vehicle to ensure proper operation.


NOTE: The principal parts of the clutch system are the driving members, the driven member, and the hydraulic system. The clutch housing is part of the manual transaxle assembly.

Driving Members
The driving members consist of two flat surfaces machined to a smooth finish. One of these is the rear face of the engine flywheel, and the other is the front face of the clutch cover assembly.

Driven Members
The driven member is the clutch disc. The clutch disc is splined to the input shaft. The clutch disc slides on the splines to provide clutch disengagement and engagement.

The clutch disc is held in contact between the flywheel and the clutch cover assembly by the pressure of a diaphragm spring in the clutch cover assembly.

Hydraulic System
The clutch release system consists of a clutch master cylinder, remote reservoir, tubing and an clutch actuator cylinder assembly. The clutch master cylinder is mounted to the front of the dash and is controlled by a pushrod connected to the clutch pedal. The clutch actuator cylinder assembly is mounted inside the clutch housing. Tubing connects the clutch master cylinder to the clutch actuator cylinder assembly.
