My thought is the pump is worn out.As they wear the 'tolerances' get larger and the oil gets thin as it warms up. About the only way to 'fix' is to replace the pump.However,testing is a good idea,if you can.My 'old' 706 with 13,000 hrs is getting that way too.

If the fluid is new Hytran, ignore this. New oil can have much more stable viscosity than old oil. It may be possible to use a combination of Hytran, and 30wt non detergent engine oil to keep it operating. If this system is never connected to remotes, putting a blend in it will not contaminate other tractors. Jim
