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?

Re: Wacky Clutch
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" <romainm@sympatico.ca> wrote in message news:41C32E33.D7D121EA@sympatico.ca... > LOL! > > Haven't done that for a while, funny.... > > It froze on.

Re: Wacky Clutch
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.
