Maunual trans noise?

I have a 2002 TJ Sahara with a 4.0 and a 5 speed trans and I am getting a noise from the trans when I let the clutch out in nuetral. When I push in the clutch the noise goes away. First thought was the throwout bearing so when I installed the SYE I decided to go the extra mile and replace the clutch, pressure plate, and throw out bearing. I put it all back together and still the same noise. Any suggestions?

By the way the truck only has 75000 and the trans fluid is at the right level and looks very good.

My '02 Sport does that as well, it's just a naturally noisy throwout bearing. Nothing to worry about in my case. If it's not real loud I wouldn't worry about it.

the nv3550, the 5-speed that jeep started using in the 4.0's in 2000 is just a naturally noisy trans. most people describe the noise while in neutral as a marbles sound.

Some comments on this thread are backwards.

When you push the pedal DOWN the throwout bearing is used - if it's going to be noisy it will now.
When the pedal is UP the bearing no longer spins, so it cannot be the TO bearing no matter what gear the trans is in.

New those 5 spd transmissions made a little bit of noise running free, but not objectionable. Depending on how loud is loud you may be in for some repairs.

But first, I'd dump and refill the trans with new CORRECT trans oil - there's zillions of trans oils that claim they are the best. Some will make it shift hard, some will cause undue wear.
I only trust the proper trans fluid from a Jeep dealer. It may cost you more - $2 or 3 to do it right.
No additives either.

When the clutch pedal is depressed it creates a load on the throwout bearing removing all of the play in the races and clutch fork, thus making it quieter. Without the load the bearings rattle in the race, and rattles within the clutch fork itself creating the noise. A bad throwout bearing will make obnoxious amounts of noise when unloaded. There is always a rotational forces on the throwout bearing from the shaft that it rides on and minor contact with the pressure plate.

Some light reading

Gee - I must have been calling it wrong for years! I had no idea that a TO will make a grinding noise all by itself without it turning. Does it do it in the box too?

The TO is not supposed to be touching the fingers when released, thus not turning. The spring in the slave cylinder is supposed to pull it back slightly.

I guess I'll have to contact several hundred happy customers and tell them they aren'y happy after all.

BTW - according to the PO, he'd replaced the TO - the new one is exactly just as bad as the old one? That's one for the Smithsonian, or at least Ripley's!

rrich you should really try chilling back with some drinks sometime. Maybe even smoking a cigar to relax a little.

The clutch kit was only $165 and it took me about 3 hours to drop the tranny and replace it. No big deal my buddy has a shop with a lift so it was really easy.

Thanks for all of the replys guys. So it seems that the trans is naturally loud wich is fine with me its not that bad. I was just wondering if there was a known problem with bad bearings in the tranny and apparently there is not and its just noisy. rrich I understand how a throwout bearing works but sometimes if something is noisy when there is no pressure on it and it becomes quiet when you apply pressure to it like pressing the clutch. I know generally they dont make noise until you press the clutch and it is a loud squeeling noise. The noise i have sounds like a loose bearing. But regardless in my original post i was not asking if you thought my throwout bearing was bad. I was asking if there was a known problem with a bearing in the trans. As i stated I have already replaced the clutch and bearing and I still get the noise. But thanks for the opinions I will just deal with the very small amount of noise. I just wanted to make sure that it wasnt a problem and it would brake one day on the highway.

My '02 has made that noise from day one. Purchased new with 5 miles on it in May of '02. I talked with my mechanic and with the dealership, and folks I trust. I was told this is normal. The clutch is self adjusting, and well its a jeep.

And yes when I push in the clutch it goes away just as you stated. I have 115 k miles now on the original set up. Marbles is a great way of describing it.

Now if you want noise, my 3B sounds like a washing machine full of bolts sometimes when I slow down. When I let up on the pedal to start the braking sequence (still has 11" front drums/9" rears) it is LOUD. Same thing, its a jeep and they are noisy. The 3b has the original T-90 and everything works as it should.

Its just that dang clack clack noise it has started lately from the engine area that is irratating.

Hello:

I have the "marbles sound" when the clutch is let out. When pressed in....there is no noise. Will the sound get worse? Trans shifts great, clutch grabs fine.

I have the same issue with my '03 and, over time, I've found that I've come to expect the noise...and even LIKE the noise! It's definitely a Jeep thing.

Cool

I have a 03 wrangler sport with 40,000 miles on it. It makes the exact same marbley noise you guys are talking about. Everyone that I talk to has the same problem. Gears shift nice and smooth so that is all that matters to me.

The noise is not a problem, it is nothing more than the input shaft and bearing spinning from the engine turning the tranny's input shaft when the clutch is out. Step on the clutch and the transmission's input shaft and bearigns are no longer being spun by the engine.

I have an 2003 with the same problem. BUT I just got mine out of the transmission shop and after $945.00 later I still have the noise. But that cost did include a new clutch and changing the fluid and the fluid in the transfer case.I brought it back to the shop yesterday to complain about the noise and the guys at the shop looked puzzled.

That's why they gave you all those speakers. Turn up the music and you will not hear it anymore.

Mine has noise

I bought a used 2002 Sahara, 75,000 miles. On the drive home I noticed the sound you guys described, 30 day warranty on the drive train. Took it to the jeep dealer(different than the one I bought it from), asked the lead mechcanic to listen to it, he didn't have an answer for it. Can you guys hear the sound from outside your vehicle?

Bought my '02 Sport in August this year. Only 27000 miles. Same noise. Brought it to mechanic friend who also confirmed it was normal. Was told as long as there is no serious noise when clutch pedal is pushed in, it's fine. Everything is normal. Coming up on 30000 and plan to change out all the fluids and start fresh. Any recommendations on fluids for the older jeeps? Synthetics or the good old fossil stuff. I have a buddy who is an Amsoil distributer...

I feel blessed to have the ax-15. Quiet and smooth. Really don't care if the nv3550 is better or not. Just hear to many horror stories about it. Strange noises and being temperamental with fluid. Yikes!
