wining noise thats consitant at idle--but goes away when clutch is pressed???

[Mike]

I dont agree with this. I have the same problem with my trans to.
All my seals, clutch, TO bearing are brand new OEM parts right from the dealer. Shit I even got my fluid from the dealer.
I still have the same noise with only 1000 miles on all the parts.
From what I have been told, and from searching. The noise seems to be the output shaft bearing (23121224164). This problem is usually caused by the shims wearing out between the bearing and housing cover.

You posted the part number for input shaft bearing, the output shaft bearing is PN#23121224166, correct? I am in the same boat, and am hunting for answers. How tough a job is this, if you have no problem pulling the trans on your back, in a freezing garage, 3 or 4 times in a row? Whats the best way to diagnose this, cause I have a whole extra tranny waiting for me to toss in.

It's a good idea but seriously, it's the the fucking bearing. What have all the techs said so far? The bearing.

I'm with the fiddler on this one. It's the throw out bearing.

What if the noise is present at all times when the clutch is engaged, including while driving in-gear? But does away any time the clutch pedal is pressed in?
