The other day I did some more listening and trying things out to see how it affected the whistling noise.
When the car is idling, at a stop, at normal operating temp, I noticed the sound can NOT be heard when the transmission is in gear for, R, D, OD, 2, or 1.
However, as soon as you shift into P or N, the sound becomes very audible.
This leads me to believe it is something to do w/ the tranny.
If it is the tranny, is it anything major?
The tranny was just rebuilt ~3K mi ago., but since this car sat for about 6 months, it is already past the 1yr. warranty.
Thanks.
