Case 2590

[Keckr]

My case 2590 has remote hydraulics for the first 30 minutes to 1 hour of operation depending on outside temperature. After the oil warms up I lose remote hydraulics. If I push in the clutch I gain rear hydraulics again but as soon as I let out on the clutch the remote hydraulics fade away. I'm asking for anything to look for or to replace TYIA.

You have a big internal leak in the power shift transmission

Roger has it right, you may be able to narrow the leak down by seeing if the lift works depending on which clutches are being used in different powershift positions, shifting takes different clutches in and out as you shift. By knowing which clutch combinations give you which ranges you can figure it out.
