I would agree that it is probably the control valve. My dealer is replacing the control (under warranty). They can and did test the cylinders for leakage pretty easily, but in my case the 'sag in my FEL is also seen in the B'hoe and the 3pt hitch. This would seem to indicate a constant leak in the 'return' taking away from over-all hydraulic pressure - the system 'sags' even when under power. It would only need a 'leak' in one controller to affect a system with 'power beyond' feeding a B'hoe and a FEL etc. A cheaper fix would probably be to replace the valve seat.
