By the wonders of YouTube.

You should be able to hear a sort of whiney noise throughout that follows the revs. happens when static and in neutral also. Only noticed it recently.

N54 6AT with about 70k on the clock.

Is my gearbox on the way out or am I just paranoid?

It's an auto, so bits and bobs will be spinning to some extent.
OP you can't hear anything from the clip, apart from the mic/phone/whatever rattling about and some mic hiss.

First port of call if you suspect an AT is to change the fluid if it's not already been done.


OH and...

It's an n54 with decatted downpipes - those are just lambda sensors throwing errors. I can get my JB4 to clear them but it reminds me to check every so often for anything else.

You need to turn your speakers up - I just checked - it's a clear mechanical whining that follows revs. You can only notice it at low speeds because otherwise it gets drowned out by the raspy goodness and turbo whine.

I've bought the bits and will be changing the trans oil this week, see if it makes a difference.

Tried e90post, they said change the trans fluid and check again. Cheers for any assists.
