GT500 hissing noise

[DocGT]

I absolutely love my new ride.
This thing is a beast.

I do notice an odd hissing sound, or maybe more of a higher pitched fluid through a line sound, that seems to randomly be present when driving, and I definitely notice it when I shift into reverse.

Does anyone have any idea what I’m talking about? Much thanks.

Mine does the same thing. Very noticeable with windows down and backing into the garage. It's been mentioned before and I think some alluded to fluid pumps in the DCT or possibly a pump for one of the coolers.

Alright... the OP threw you a softball...!
Someone insert "Hissing Cobra" joke... C'mon!

I wish I would have thought that far ahead, but you caught a joke I wasn’t even trying to make . . . Although I’m definitely taking credit for it now.
I definitely get a hissing noise, it I’m now considering accepting it as the sound of an angry cobra!
Nice catch.
