Well if you have been following the engine bay sound threads, some of you willknow I tracked that sound down to the Transmission Control Module. Knowing itslocation and giving my best technical guess at it being one of the transmissionsolenoids, it was off to GM in the USA to get the technical reason for thissound.
With a very nice return email from them, they asked me to contact Holden backhere.
This is where the loop starts.
Holden Head Office, advised me to contact a Dealership, the Dealership asked meto contact Holden.
So after I forwarded the email from the parent company GM back to Holden, theyadvised they would do a little research.
Today I got the call following that research.
That sound is "classified". I kid you not!
Holden advised they were unable to release that information to a customer, whojust happens to own the item...
So I guess in a world of IP, TM and Copyright, Holden and GM are keeping thisunique sound under wraps.
Still, give it a few years and it will be on ITunes for the world to enjoy.
I'll have to use this at work next time I'm asked by aircrew, "whats thatsound in the engine nacelle?"
