Wasn't sure but it sounds like you are using the autopilot's alitutde hold. Just to add to what Andy was saying, the altitude hold as currently implemented doesn't work realistically. If I'm not mistaken the 747 autopilot and autothrottle system should be holding the pitch at the preset angle for cruise with trim and the throttle should be controlling rate of climb/descent. You could try that method manually to see if it will trim.
