This is a tough one. If I had to guess, I would say the noise is coming from the transmission, but is nothing to be worried about. In the past, I have heard similar things in these trucks but have never been able to identify where it comes from other than the possibility of a bearing in the transmission. Regardless, the sound never seemed to change and the customers never had problems.
I hate to say it, but I have to recommend that you wait to see if it worsens. If it does, then perhaps one will be able to locate and repair it. At this point, it will be nothing more than a guess which usually leads to money spent on parts that are not needed.
