Greetings. Have a '96 automatic. For the past few months I've been noticing (as best described as a) whistling sound as I accelerate. Noise can't be heard the faster you go but then obviously, becomes audible when I slow down. Another descriptive example is like a radio frequency sound/pitch. Looked underneath (not a mechanical guy) thinking CV boot issues but all seem intact, no grease leaking, no tears. Vehicle handles well, nothing noticeable that could relate to the noise. A buddy of mine said to check the transmission fluid as the pump could be making the sound but all is well in the fluid department. Any thoughts or suggestions where to look, what it might be? Thanks for reading.

Also, I can't replicate the sound while in park and revving engine.
