Is the oil level low in the torque tube and high in the rear end? If so then you likely have a blown hose in the rear end going to the cyl. or a packing ring on the cyl. blown.
There can be several problems inside the pump itself but look for the simple things first.

Thanks dave I also forgot to mention that it also has a seprate auxilary valve for the remotes on the back and when I pull it both ways it makes the arms come up I dont know why it does it because its for the rear remotes and sometimes the arms come up and I cant push them down I dont know whats wrong with it

Like Dave said, check hydraulic fluid level and then try it for awhile again and recheck. You could be loosing it with the hose or the ram. Hopefully it's the hose, but you still have to take the two point lift mechanism off of the rear end to get at the hose and change it out.

Disconnect the auxiallary valves and it will work fine. Maybe unhook the hose plugging into the standard remote outlet??

It's not plumbed the way it normally should be....can't see everything from this picture. Usually the oil is pumped thru the steel line to the Transport valve, so get rid of that "tee" and connect the elbow back into the side of the Transport valve. Then disconnect that hand shut-off valve and install a Pioneer female coupler on the rear of the Transport valve which is the outlet. Then the arms should go up and down with the long lever on the steering wheel. To operate the auxillary valve, you then need to plug it into the Pioneer coupler and lock the long steering wheel lever in the "up" window. I assume the aux valve has a line or hose returning the oil to the torque tube under the sediment bowl???? When using the aux valve your pressures will be limited to 2000 to 2200 psi??? or whatever the aux valve relief is set at. The tractor is set for 3700 psi on the lift arms and Pioneer coupler outlet. Someone else needs to post a good picture of how this should be plumbed.

Ok I went out in the rain and took a pic just for you guys. Here is my D17 SI with the two way valve setup, I think it is factory. In this pic it is set up to use the lift arms, I uncoupled the line from the transport valve and plugged it into a female coupling of the two way valve just so it wouldn't be flopping around. You can see that the return line from the 2-way valve dumps back into the rear port on the transport valve.

OK...so the rear port is the return port? then get rid if the shut-off valve and get a Pioneer male nipple in it's place and install a Pioneer female coupler on the rear of the Transport valve and leave it ( the male nipple) unplugged for lift arm use.

It's permissible to have to pull the lever below horizontal to get arms to go down. Overfilling isn't the problem. May have "hold" valve problems inside, which would require removal of the pump to repair. Before removal of the pump make sure you know what the pressure is...should be 3700 psi maximum, but anything over 3000 is usually enough.
