Wacky Clutch
'02 TJ with 4L and NV3550:
Anybody have a clue as to what would make clutch disengagement intermittent??? I'm driving through a little village and press the clutch pedal to change gears, and _nothing_ happens - the clutch remains engaged. I force it into neutral, then can't get it into any gear at all. No amount of clutch pedal pumping makes any difference. Not rolling anymore, I shut the motor off and put it into first gear, then start it up with the clutch pedal pushed in. The TJ lurches a little bit, the the clutch "breaks free" and everything is completely normal for the three mile drive home, clutch is working fine. The powertrain is still nominally under warranty, so I call the dealer and make an appointed. The fifteen mile trip to the dealer is completely normal, clutch working fine. Naturally, after keeping it for a couple of days, Dealer calls and says there's nothing wrong with it. What gives? Could this somehow be related to the increasing noisiness for the normally noisy NV3550? /Peter |

LOL!
Haven't done that for a while, funny.... It froze on. Literally. Hit any puddles just before?

No, no puddles that I recall. They would have been frozen anyway. It hasn't
been offroaded since before freeze-up, so it's not like I just did some fording or something. I can't say I've ever heard of a clutch being literally frozen before. So the intermittent warm idle "thunk thunk thunk" from the bellhousing and the new bunch-of-marbles-rattling-in-a-can-when-coasting-with-clutch-in sounds are unlikely to be related to this disengagement anomaly? (The new bunch-of-marbles-rattling-in-a-can-when-coasting-with-clutch-in sound is not the same as the old bunch-of-marbles-rattling-in-a-can-when-in-neutral-with-clutch-out sound. The latter is standard NV3550 fare I gather.) /Peter "Mike Romain" > wrote in message ... > LOL! > > Haven't done that for a while, funny.... > > It froze on.

Ouch....
That could be something like a broken part that jammed the slave before falling to the bottom. Does yours have an inspection plate on the bottom you can open to see if any 'fingers' are laying around down there? Mike Peter Pontbriand wrote: > > No, no puddles that I recall.

Hi Peter,
Sounds like the pressure plate or the dampener springs in the disk are coming apart and jamming their release, it may be a rock in there, but not if your luck is like mine. That's if the clutch pedal wouldn't go to the floor, if it does that's in the hydraulics.

My first guess was... air lock in the hydraulic line. But you have
rattle... that ain't right!. The $teeler not hear that?

I just picked it up from the "there's nothing wrong with it" dealer. While
there, I asked if they had taken off the inspection plate and taken a look inside. They hadn't. I asked what they thought of the "thunk thunk thunk" and marbles-in-can sounds, and they said they didn't hear anything unusual. But then, if they had I'd bet they would have charged me - at least the bill was only $0.00 for them to simply drive it around and declare there's nothing wrong. The sounds are definitely still there, but the clutch is still working fine now. By the way, the "thunk thunk thunk" sound can be felt too, notably in the brake pedal. There's something hitting something somewhere, but I'll be jiggered if I can figure out what. /Peter "Mike Romain" > wrote in message ... > Ouch.... > > That could be something like a broken part that jammed the slave before > falling to the bottom.

When it happened, the clutch pedal did go to the floor, yet there's no leaks
and everything with the clutch action has gone back to normal of its own accord. Only the odd sounds/vibrations remain. /Peter "L.W.

Would an air lock just magically disappear? And no, the dealer claims to
have heard nothing unusual. I suspect they didn't drive it enough to experience the "thunk thunk thunk" business, since it only does that when fully warmed up. The NV3550 is known to be a noisy transmission. Mine always has been noisy when idling in neutral. What's changed recently is that now it makes the same noise when coasting in gear with the clutch pedal depressed, perhaps even louder. It didn't do that for the three years I've owned it and now it's just started. New sounds make me think _something_ is wrong, but it seems the dealer does not concur. /Peter ----- Original Message ----- From: "JimG" > Newsgroups: rec.autos.makers.jeep+willys Sent: Friday, December 17, 2004 5:42 PM Subject: Wacky Clutch > My first guess was... air lock in the hydraulic line.
