Poor lubrication to the O/D unit often causes the dark fluid - a result of not enough fluid volume through the intermediate shaft to the O/D unit. This was the root cause of many A518 failures - not enough coolant flow to the O/D planetary set would over-heat the fluid. I'd look into an up-graded intermediate shaft that has larger coolant holes.
