Leaking clutch fluid

My truck is a 2002 with the 5-speed NV1500 tranny. One day driving home I lost almost all resistance in the clutch pedal; I could push it almost completely to the floor before I felt anything. Mind you, this was after I had worked the truck fairly hard from hauling mulch. Anyways, I got it home and the master cylinder was almost dry (STUPID mistake on my part). I filled it up the next day and the pedal felt normal again, but it seems like the longer you drive it the more play it gets, and the less fluid the master cylinder has. It seems to lose the most fluid when the truck has a load although I think it still loses some with normal driving, but it's not as bad. The front bottom portion of the bellhousing is wet and it feels like brake fluid, so I'm thinking the slave cylinder is leaking. Any opinions or ideas before I drop the tranny to replace the Slave cylinder? Is it possible that I got air in the system which could some how be making it leak? Thanks in advance

Re: Leaking clutch fluid

Thanks for the input. I was advised to just buy a clutch pack and do it all at the same time, but at 73,000 miles I don't think I need a clutch just yet.

Re: Leaking clutch fluid

At 73,000 you could very well need a clutch, or not. It really depends on how it was driven.


Alldata allots for 4.7 hours of tech time to do the clutch, and 4.5 hours to do the slave cylinder, so I would say it's probably worth the time to just do the clutch at the same time. If you pull it apart and the clutch is in GREAT shape, then put it all back together and return the parts.


If you do the clutch, make sure that you resurface the flywheel.

Re: Leaking clutch fluid

Just a thought on resurfacing the flywheel - It would be like $40 to resurface it and it's like $50 for a brand new one. I'm just sayin'...

Re: Leaking clutch fluid

Depends on what year and model your Jeep is and in part where the leak is coming from. If it's a '97 to '06 Wrangler it's easier, and cheaper, to replace both. It is a sealed unit, very easy to install. Other models have different needs and fixes.

Who said anything about a heep. He has a s10 that is a 02 with the nv1500 which means he has the 2.2, clutch kits are cheap. If it were me i would replace both the clutch and the slave. Thats me I dont like doing things twice. Also if your clutch disc is soaked with brake fluid then replace it anyway, its not good on the disc.
