Hate to be the harbinger of bad news Joe, but to fix this problem you have to split the tractor. In the middle of the torque housing there is a seal between the hydraulic reservoir and the transmission. Hopefully this is not true; but most probably the case.

Uncle B,
Disagree on the cause of problem.
'IF' the fluid levels were the same (relatively), the seal would probably be the way the oil is getting into the xmsn.
But, AC Joe had said that the hyd fluid was goin down so much after filling that it was off the dipstick and the xmsn/diff fluid was increasing even more.
I suggested he try leaving the levers in the down postion so that he could be certain. If the pump is not engaged, the oil would stay at the same level.
Another test to determine if the hose is shot, is to move the lift arms to the up postiion (if possible) and leave lift lever in hold postion; then push down on the arms....if they dont hold, the cause is likely the hose, or cylinder seal inside. There's a big difference between taking the lift arm housing off and splitting the tractor.

Gatz, Thank you very much for the help. Im gonna look at it this afternoon. I forgot to mention that the rear lift would not hold up or lift the rear blade. The broken hose problem sure sounds like it could be the problem. Im not as familiar with AC as I am with Deere and IH. Does the pump have to come out or require a tractor split? Thanks again for your help! Joe

Joe,
The pump does not have to come out, nor does the tractor have to be split to get at the hose and/or lift cylinder. Just need an overhead lift or cherry-picker.
Besides the hose (&/or cyl seals) you'll need the large gasket for the lift-arm housing, the gasket for the transport valve/distribution block on top of the differential (this could be made by hand) and the small o'ring for the cyl anchor pin. You may want to put in new cylinder seals while it's apart and replace the PTO seal at the rear of the housing. Write down your tractor's serial number for ordering parts.
I strongly encourage you to get a shop manual.
Either AGCO's Service Manual for the D17 or IT's AC-201 manual. I could copy the 2 pages in the AGCO manual and email them to you. Let me know.
Gatz
