Anyone with an Automatic heard a hissing sound when in gear?

[stangguy94]

I have noticed a hissing sound when I am sitting still in reverse or drive. IF you put in it nuetral or park it goes away. I sometimes could hear it when I would get on it pretty good as it shifted thru the gears. Anyone else heard this? I didn't notice it when I first got the car.

i got an 06 gt auto, can you be more specific in the hissing sound, maybe at higher rpm or maybe the hissing sound sounds more like a whistle?

Yep...I hear it.

Happens whenever I'm driving at any speed. It goes away when I come to an idle....

I though it was radio interference but I have no idea what it really is...

i hear it at idle in gear with the window down. it sounds like a vacuum leak or something. if i go down the road and go about 1/2 to 3/4 throttle so the exhaust isn't real loud i can hear it as it changes gears. i dunno.... just thought i'd see if anyone else had heard it.

None with mine that I have noticed. Next time out I'll listen to see if it's happening with mine.

Mine makes a noise somewhat like a hiss/whistle combo(something like a real low volume turbo spooling up). I only hear it at WOT right before it shifts. I don't hear it any other time. Will be interesting to hear if it is still there after I get my tuner...
