Has anyone experienced a hissing sound coming from the center console (possibly transmission) area during acceleration and deceleration? When I reach over 1500 RPM the sound is minimal, however it is louder as I go faster and is more prominent when I decelerate at high speeds. It's not audio or electrical interference; sounds more mechanical almost like the AC unit releasing air. I did a search in CL and it might possibly be the transmission pump (gear pump). I'll be taking it soon, but wanted to see if anyone may know what it is ahead of time. It's an 08 with 70K. Thanks.
