1997 BMW 540i V8 Two Wheel Drive Automatic 165000 miles
When running at steady speed car sounds like its changing gears up and down constantly but looking at the RPM's staying steady its not changing gears. Transmission works fine and changes as it should.
Also rough roaring noise when cruising speed is steady and car not pulling but maintaining speed. Stops when gas is increased. Doesn't do it ever above 80 MPH.
May be two separate things.
