Transmission Whining at idle

Finally got the 280SEL 4.5 up and running pretty good, but now I'm having issues with the transmission. Performed tranny fluid change with new filter and seals. The A/T switches gears well, no slipping of hard shifting, and no problems when the car is cold, but once driven for more than 15-20 minutes, the transmission starts making a whining sound. No noises in park, and no noises when actually moving, but when in Drive or Reverse and at a stop, it sounds like there is a woman screaming under the car. The noise comes on slowly after about 15 minutes of driving, when stopped at stop lights or in traffic, just a faint whistle at first, then with more stopping, to the point where people at looking at the car. I'm thinking this isn't good! Any opinions out there?
