I am having trouble with my JD 2640 hyd they were real slow then they went out completely,found the transmission pump was broke (a gear was stripped) replaced it and it is working but the tank above the main pump is empty and I fill it up and the hydraulics work just fine until the main pump uses up the oil with steering 3 pt and remotes which does not take long,then nothing works also the pto is turning and it want shut off,I have checked every valve on it and the stroke control valve but I am not sure why the tank in the front does not fill up or the suction line to the pump is not supplying oil to the main pump or is it bad? Thanks
