Squeak From Transmission

[Cadmoon]

Hey guys im getting some funny noises from my gearbox (R33). I can only hear it when the car is warm, when idiling in neutral with the clutch pedal out there is a squeek coming from the box but it goes away when i push the clutch in. Any ideas?

Thanks

Thrust bearing. Very very common.

How big a problem is it? The box will need a rebuild at some point in the future because a couple of syncros are on the way out, will leaving it for a while cause any major problems?

It's not in the gearbox. It's in the bellhousing with the clutch.

Yah but i can get it replaced when the box is taken out to be rebuilt.

[GTSBoy]

I would have thought that would be obvious.

[Cadmoon]

so did i, still dosnt answer my question about how big a problem it is.

It's not a huge problem. It's not going to force you to pull the gearbox. It's not going to force you to rebuild the gearbox. It will get worse over time. It might fail. It would be better to replace it than leave it for a long time. If you are pulling the gearbox to rebuild it then it is trivial to replace the throwout bearing. If you are not going to pull the gearbox to rebuild it, then pulling the gearbox to replace the throwout will add some cost and effort, but it's not going to bankrupt you.

Thanks, i might have to do the box sooner than expected.

Yeh as said, replace it if you're going to have the box out anyway. It's a $60 or so part, so not like it's a massive problem. But mine has been making the whirring noise for a good 2 years now. It hasn't got any worse in that time, so I haven't bothered pulling it out. If it starts to get louder then I'll pull the box and replace it.
