2000 Boxster S (6-speed) transmission noise

The transmission noise sounds like a whine and it makes the noise while going straight or turning no difference. The noise gets louder the faster you go and if you push the clutch in the noise goes way. We took the gear box out and can’t find anything wrong…any ideas?

Is the wine speed dependant or Rpm dependant? Cold, hot, all the time? Leaking? All gears?

The wine is speed dependant but you can hear it even when you are driving slow. Hot or cold makes no diff. No leaking. And it makes noise in all gears but it gets louder the faster you go. Thanks for the help.

Milage? Did happen all the sudden or over time? (as in getting worse).

Seems every time I answer a question with conventional wisdom, someone pipes in with some common elixir specific to the 986,

Since no one has, I’ll give it some conventional logic:

-Clutch in (or out of gear?) no whine while it’s rolling; so it’s not: anything that’s left turning. That would be wheel bearings, half shafts, differential part of the transaxle, throwout (thrust) bearing, pilot bearing.

-Engine rpms have no effect by itself (out of gear)so: nothing on or in the engine, water pump, idler, generator engine bearings etc

-Wines the same independent of what gear your in; not the gears or there related bearings.

-No grease on the ground and your sychros work fine so; being out of gear oil is pretty unlikely.

- Directly related to cars speed with trans engaged; and so something that is spins with the wheels and the trans.. Not the wheels (above) , not the gears themselves (above) sooo…

That leaves the trans, something very specific in your trans…maybe the output shaft when it has a load on it and thus it’s bearings or gears

I’d take it to an indy shop soon and prove me right or wrong. If it’s a howling bearing in the trans, it can fly apart really wreck your trans (not to mention your day)

Regards, PK.

While it is a bit tough to give an exact cause without actually seeing this, the 4 point bearings on the mainshaft and pinion shaft are known to go out on these from time to time.

We have done quite a few of these and while they are not the most difficult things to work they do require a 45 ton press to press the gear clusters apart. Not really a job for someone who has never done this before.

I realize that you post is a bit older, but if you are still having issues with this feel free to contact me and I will be happy to talk to you in more detail about this problem. Depending on where you live I might be able to recommend a good shop nearby to you, or we can always look at it too.

Just trying to help,
