Is it a top drive power shift pto? I believe certain 3000 series Allison’s had this, almost like a power tower or a power splitter ahead of the actual transmission drive arrangement itself. These were to increase the amount of available horsepower to a pto, it far exceeded what a 6-8 bolt pto could put out.
