My daughters Corolla has 150k. She came home with it this weekend. I drove it., on 2003 Toyota Corolla

I notice a vibrating hum like sound. maybe from the transmission. The sound gets faster as the car accelerates. Nothing while at a stop, the engine runs very smooth. it's been a great car...Any idea's
