2001 Oldsmobile Intrigue Transmission is whining

Recently when I accelerate from a stop sign or to merge in traffice I am hearing a whining noise that mimics my acceleration pattern. The car seems to be working fine and I don't notice hard shifting or anything, but the sound is noticeable. I recently had my car serviced and all fluid levels were checked. Is this something to be concerned about? Or is it an old man being nervous about nothing. Thank you
