Well recently started hearing this rough sound when the clutch is out while the car is idling. I know it cant be good.

Have a listen. Anyone ever hear this before? The Rough Sound comes and goes as I put the clutch in and out during the clip.

The tranny has 240,000kms on it and hasnt been cracked open for a clutch yet.

No big deal if it is shot, just kinda hoped it would go longer.

 

throwout bearing, mine did the same thing, more or less just annoying eventually it will need to be done. my TO bearing got really loud before i replaced my clutch. 292,000km on original clutch

I concur. That is the throw out bearing on the input shaft of the tranny. It is the piece that attaches to the clutch fork that pushes on the pressure plate to disengage the clutch. You can drive it for a while, but start saving your pennies for a new clutch and throwout bearing.
BTW, kudos on the sound clip. Most people just try to describe the problem using broken getto english. Its harder to try and decifer the words than solve the problem.

Thanks a lot guys.

Its kinda easy to make sound clips when you use your laptop in the garage as a Service manual and its got a built in microphone.

It's more of setting aside time for the labour, my parts maxima has a factory replaced tranny and clutch with only 35,000kms on it.

I think ive got enough parts to keep this maxima going for half a million clicks.

 

It sounds like it is only making the noise when your foot is NOT on the clutch, right? the noise is NOT there when you press the clutch down right? If this is the case, it is NOT NOT NOT NOT the throwout bearing. The throwout bearing DOES NOT SPIN when your foot is off the clutch, so if your car is making noise when your foot is off the clutch, then it's obviously not the throwout bearing. It is your input shaft bearing, inside the transmission. The throwout bearing only spins (and could only make noise) when your foot is ON the clutch. If your the noise isn't there when your foot is on the clutch, then it isn't the throwout bearing.

I work on transmissions all day every day, I've replaced 3 bad input shaft bearings in my own maximas - and the input shaft bearing is your problem from what I'm hearing. It's NOT the throwout bearing, trust me.

 

the sound comes in when the pedal is depressed.

 

No - it isn't. Look at his post again. He said the noise is present when the clutch is OUT (i.e. foot NOT on the clutch). It is his input shaft bearing. It is not the throwout bearing. 10000000000% guaranteed.

 

your right, i mis inturpreted it twice LOL. Them midnight to 8am shifts 6 days a week will really mess u up hehe

 

Yes, the noise is made with my foot off the clutch 100%. and goes dead silent when i push the clutch to the floor.

Is the rebuild on www.motorvate.ca. the one that I need to do for this tranny?

 

sounds exactly like my tranny (and I mean exactly). I also have diff bearing noise too though (it started first). If all goes well I am changing my tranny next weekend.

 

neal you still sellin trannys? i thought you were a while back.

 

my new (had it for 2 weeks) 96 se just started making this noise, i believe the clutch is pretty new, not the original for sure. can i just change this bearing without replacing the tranny? is this an expensive fix?

 

It is some kind of bearing. If the sound it present when your foot is not on the clutch it is most likely the input shaft bearing. I had this problem, spent 700 bucks to get the bearing replaced and a warranty on my tranni. Do not drive on this too long as it could chip away the tip of your input shaft.

 

Motorvate does only a partial rebuild - replacing the differential carrier bearings only. To change the input shaft bearings you need to take more stuff out - basically you also need to disassemble the shifter mechanisms and remove the input and mainshaft. You should absolutely replace all the tranny bearings and get the housings cleaned if you're going in this far.

Generally there is no need to disassemble the shafts themselves, unless you have a bad synchro.

one week later and not even 500 miles and the noise is getting really loud and very noticeable while in 1st and 2nd Gear. This thing is finished.

 

If you keep on driving it you will damage the end of your input shaft which is around 400 bucks(+installation)....I would take it to a tranni shop to get fixed ASAP. DO NOT DRIVE IT UNLESS YOU ABSOLUTELY HAVE TOO.

 

That sound on that transmission is unquestionably a bad input shaft bearing. Nealoc187 cannot be more correct in the information that he gave you. I have rebuilt about 15-20 nissan maxima transmissions and these transmissions are notorious for having bad input shaft bearings. If you keep using the car like that it could damage the clutch housing, cut into the seal and leak oil into the clutch. If you need a transmission I have 4 available. All fully rebuilt. New synchros and new bearings. Feel free to call me at 678-371-6185 and ask for Marvin.
