2805 hydraulics appear to be sucking air, no p.s, brakes, pto, or hydraulic lift, trans fills up with foam after running a few minutes.
The trans is over full with oil.
I think the leak is external, the tractor has the canister type hyd. filters, 24 speed has been changed to 8 speed.
Does anyone have any sugestions what to check, or do I just pull the filter assembly apart and hope I find the leak?

I'd almost bet you have a seal or more bad on the right hand pump. I have seen this before. I had one once that the right hand pump was bad even though the hydraulics appeared to work fine, the left hand pump was pulling air from the right hand pump. The left pump operates two auxillary cicuits. The right pump operates the pto, difflock, and transmission on the low side of the pump. The three point and third auxillary, if it has one, oprate from the high pressure side of the right pump. The early 2805 had a seperate power steering pump driven from the engine in the valley by the injection pump.
