My 2004 all wheel drive with an auto tran wines more noticeable at lower speed? on 2004 Toyota Matrix

Started to hear the nose 2 weeks ago and it is always a bit to winey now an it is only in gear and going forward.
It most noticeable at lower speeds 10 to 25 mils hr.. Trans fluid is fine and shifts well..
