I have been reading these posts about the whistling noise and I am having the same noises.
Other issues that I have had:
Rear diff replaced due to 12 pt pinion nut bulletin
Left and right front CV axles
What I am experiencing is that this whistle is between 30-45 MPH and comes in under acceleration but right when the TC locks, then it stays for a while after letting off the accelerator. I have a feeling that this issue is in most of the dodge ram trucks. I was given a 2012 with 27,000 plus miles on it and the noise in that one was just as bad if not worse.
Its your transmission cooling lines to the front of the truck, you need to install a rubber piece between the support and the lines. This has been covered in many threads. I have the same issue till I installed my Magnaflow, now I rarely hear it
