Could the sound be coming from the transmission area? If not, we need to rescan the computer. There are several valves this could be referring to. I would scan the CAN system. CAN stands for controller area network. It ties all the modules/computers together. Here is a video:

Still, record and upload the sound. With a little luck, I'll be able to recognize it. I'm starting to question if it is related to the cylinder deactivation system which can get involved.
Let me know
