Hst trouble. 2021 2638

I had to repair the hose elbow that goes into the hydraulic fluid strainer filter after I damaged it while shredding.

I replaced the filter and the elbow, and have no more leaks. Filled the hst fluid with iso 46 and test drove. Did great when cold, and as it warmed up there is no power and the trans gets whiney. It gets to the point where it will not even move. The hst fluid now looked cloudy.

So I changed the spin on filter and all new fluid but I have the exact same result. Any ideas?

Tractor has 105 hours.

No not that I see. I'm thinking it's milky like it's got air in it. After sitting it does get clearer but not back to it looks like new.

And the power steering is hard now, where it was super easy before. Almost seems as though it has a blockage limiting the flow.
