Throwout bearing?
 

My throwout bearing usually squeaks when I push in the clutch. It's on the list to replace but just haven't gotten around to it.

But today, on a cold start the car was making this sound. It's a high pitched whine, almost sounds like a supercharger.
Could it be the input shaft bearing? Or just the throwout bearing?
The sound slightly goes away when warm, and is definitely coming from the bellhousing.

Here's the 2013 Warranty info on the transmission and dispute process

It's covered under the power train warranty which is a lot longer than standard factory warranty.

I had mine replaced at 19k miles when it made the sound. I swear the clutch feels better now and I haven't heard any sounds 3k miles later.
