When I shift into neutral I can hear a squeak coming from somewhere under the car. I can hear it best if the car is next to a wall (like at Starbucks) and I shift into neutral then move the shifter back and forth with the window rolled down. Could it be the linkage to the trans? Don't know if it's serious enough to warrant a 250-mile round trip to the nearest dealer. My 05 MCS is still under warranty.

Ideas?

Thanks
