2012 V6 PP - gear whine.. anyone else?

I've noticed recently when I'm cruising along at a steady speed that there is a bit of gear whine... I'm not sure if it's rear end or transmission, but at first I was thinking it might be the tires, until I realized that it changes sound/goes away depending on whether I'm pressing on the gas pedal (even just a little bit) to eliminate the "slack" in the drivetrain. It seems like it might be the trans, as I've also noticed that I can hear the synchros (I think) 'spinning up' as I go between gears.

The car has 26k miles on it.. is this normal behavior for the trans in this car?

I'm sort of hard of hearing (deaf) in one ear, and partially in the other.. so it's hard to say if this has been happening for a while without me noticing.. I just happened to notice it the other day.

There is a slight whine in the transmission, which I wouldn't worry about too much. If it is loud, may be worth getting looked at? (not sure)

After doing some more driving this morning, I'm pretty sure it's the rear end. It maintains a constant change in pitch based on increase in speed, and doesn't change pitch based on the gear I'm in. It's most noticeable (and fairly annoying) at 50 mph in 5th gear, maintaining constant speed... I think I may take it in to have it checked out... and while I'm there, see if there's anything they can do about the flaking clearcoat on my PP wheels.

The tranny does have a slight whine even when everything is normal. I had a a problem where my tranny was making loud whines as if its the synchros going. I went to my dealership and that exactly what it was. They replaced my 4th and 3rd gear synchros.

That's the same type of noise I hear from mine occasionally. If I catch it just right, with light load on the drive train, I can hear a whine from the rear. Only does it in certain conditions, but it's annoying when I do hear it. As for the trans, mine has been replaced already...it started whining louder than normal one day, then locked me out of 1st, 2nd a few times. The new trans is whining a little, but it hasn't changed much since day 1. I've thrown a few 7K rpm shifts at it, and still hanging in there.

You should have them checked out and make sure thereís nothing else going on, guys. Be sure to speak to your Service Manager about the noise. He/she is in the best position to let you know if there is work needed, and about and coverage you may have for it (warranty, recall, etc.).
