Transmission makes a constant whining noise

Car listed above is an i4. Having an issue with the transmission, constant whine from engine start through park, neutral, 1,2 and 3rd. Goes away when it shifts to 4th and 5th.
Its an automatic. Had an issue where it wasn't shifting right, cleaned solenoids A, B and C, not shifting issue went away. Solenoid tube mesh was blocked. Drained and filled with fluid twice. 1st drain and fill was with Castrol Transmax ATF, The sound almost went away, was reduced greatly but whenever the engine and transmission got hot, kept shifting really hard. As in hard enough for me to check rear view mirror to see if someone hit me from behind! when cold, was shifting normally. Drained and filled again with Honda DW1 and hard shifts have gone away but whine remains. Changed transmission oil filter as well. (External one.)
Any ideas would be very helpful... Thanks.
