Transmission whine on deceleration

2023 392 Durango - have a higher pitch whine when letting off the gas (no brake) at speeds above 45 mph. I’ve always noticed it but being on interstate today and letting off and on a lot to keep up with cars on a busy highway made me wonder if I should get it checked out. I drive probably 3 miles a day normally and don’t notice day to day because of that, but I will say it’s something I feel has been there from the start of ownership and with a year left on warranty wondering if it’s something to bring it in for or a normal thing others experience. It’s not excessively loud but is noticeable.
