My Explorer is having issues with delayed shifting and not going into overdrive. I took it to a trans shop to have it checked but it was not doing it when I got there. It sometimes runs fine and then will start up again. There is also a lown whistling sound when I am driving. No check engine light comes on when this is happening. I was told it could be a sensor problem.
