i have an 04 xb 5spd, and my transmission is making an odd sound when in gear. the sound goes away when the clutch is pushed in or is in neutral, but as soon as it engages it sounds horrible. it drives no differently, no slipping or grinding when shfting, just sounds like something is rubbing horribly

 

If you are still under warranty bring it in and have the dealership look at it.

 

Just a shot in the dark, but a guess would be an input shaft bearing. If still under warranty, but to the dealer you go.

 

dont know if its still under warranty. when does the standard warranty run out? its an 04

 

I wanna say it's your throw-out bearing that's the culprit?
Btw, your powertrain warranty should be 5 years or 60K miles...which ever comes first!

 

I would have said throw-out bearing (or some refer to it as release bearing) also, but he stated in the first post that the noise goes away when he clutches in, this is when the bearing is under load & would definitely make noise. Since when clutching in he is taking the load off the input shaft bearings, & the noise stops, ergo, must be an input shaft bearing.

 

like everyone else, I would also say the throw out bearing. Watch out though, because this piece is part of the clutch assembly the dealership will say that it is a wear and tear part which is not covered under warranty.

 

Just to clarify, the throw-out (release bearing) & input shaft bearings are 2 different things. The release bearing works with the clutch pressure plate to engage/disengage the clutch. The input shaft bearings (2) are in the transmission & hold the ends of the input shaft which have your gears (1 to 5) on it.

 

5/60 powertrain that is what it is there for.

 

From what I've been told and expirenced myself both the T/O bearing and the transmoission itself sucks on this car. With that statement off my chest...

I would probably guess its the T/O bearing unless you're like me and tried to rape the ____ out of your xB, then its most likely an input shaft bearing, or even worse the rest of the transmission like in my case. Either way if your car is still under warranty go to the dealer.

 

dude my transmission may be jacked. i took it in today and they pulled out the dip stick and they said it looked like liquid metal. but in my case it has a chatter sound wen i slightly let off the gas. and everyonce in a while it will have like a thunp. does anybody have any ideas wat it could be? and shouldnt the warranty cover it?
