Woody, at post thirteen you said that putting the fuse in made it stop. That means that the clutches are fine and it does not need the flush. Since it let's the pressure off the clutch when the fuse is in, but the ecu is not letting the pressure off under normal circumstances, it means that the ecu or it's associated wiring and sensors are playing up.
I would be visualy looking at the internals of the ecu, (with a magnifying glass), for capacitor, resistor, transistor or printed circuit board breaks. It might pay to check the resistor under the bonnet too.
Save the flush money for the repair you really need.
