Also, the noise in 4th would mean something, but that wasnít it. Then going in neutral at 40 mph, which didnít do anything either.

I did figure out that above 40 the noise doesnít really occur. It is more in stop and start situations. It is definitely something that spins whether I am in gear or neutral, moving and at a stop. I am leaning transmission, but not sure what?
I have a similar sound but looking more forward a vaccum related issue (another thread, long story)

Does it sound like two metal disks spinning together making a sometimes quiet, sometimes loud, metallic whirring? Not like a knock, but just a rotational sort-of-grinding noise? Kind of like a diesel engines sound but milder. With the high pitched portion
