A whining noise in the transmission is usually an indication the transmission fluid is low. Check the transmission fluid and fill it to the recommended level.
There can be many causes for a whining noise in automatic transmissions. The least expensive thing you can try to eliminate the noise is to have the transmission fluid and filter changed. Some shops will only replace the fluid unless you ask for the filter to be changed, so ask.
