Help with engine sound

[Bud Fox]

I am getting a unique sound from my truck and wanted to see if anyone else gets it. When it is running it is a very low sounding squealing,engaging sound coming from the engine area but seems to increase when I put it in drive. It is very hard to describe as you can see but wanted feedback as if anyone has heard this noise. Wanted to know if possibe TC noise THANKS(tried my best to describe)

Check The Levels !

I would check the Transmission and Power Steering levels.
