Not going into gear

[Peteycrete]

I replaced a dead head Hydraulic pump, new Hydraulic filter, new oil, checked and cleaned the screen. I have good movement with the loader, the PTO, and the 3 point. But I can not get it to engage into a drive gear. The shifter on the tree as well as the shifter in between my legs both move as they did before the Hydraulic pump dead headed, but it will not move once put into gear. I have tried all combinations of gearing options as well.

The neutral works when running the PTO. It stops when I push the clutch in.

Sounds Hydraulic. Leaking Regulator Gasket, Clogged Screen on the Valve Body?. Not the Pickup screen from the Pan Etc. There is a Shifter Spring on the shifter I look at? Unusual model on here. Fredricks shows the Reg. Gasket TCG-4310 If the shifter is in good shape I'd be looking at the Hyd. Valve body. TRANSMISSION: Yanmar Tractor Parts

I replied on the other site , one more thing could be the pressure relief spring for the power shift. it accesable from the outside of the trans.
