Where is the location for replacing power steering fluid in a 1998 BMW 740il?

Look under the hood to the drivers side of your car, there will be a black jug with a top on it with the letters (ATF) This is were the Power Steering fluid is checked and filled. Note: This is not the Transmission Fluid fill spot. There is no way of checking the transmission fluid except by lifting the car up and opening the nut that is connected to the transmission.
