Complicated ?
After many years of working on them I only figgered it for myself that it had 2 sisteemes.
1. Where the oil gets pumped in a constant circel(the low pressure side )
2. The high pressure side is like a reservoir on a hill. If you need something to work you open a tap and you have flow and pressure.

I believe I understand JD's closed center hyd systems a lot better now after reading/posting on tractor discussion forums that back when I served 13 yrs as a JD dealer service manager solving closed center problems.

I finally had time to split it. Here are some pictures. I think the trans pump is shot.

I found the pump, but haven't had any luck so far with that adapter.

Did you do your tests before you oped up the tractor ?
Very big Q !
Golden rule no 1 Do your tests before splitting ! Then you know what to look for !

It has quite a bit of scarring. I saw a few videos online and they said that it should be glass like smooth. It also has a lot of play in the shaft
Here is a video of it: John Deere 2130 trans pump - YouTube

Today I opened up the cover underneath the steering column. The oil smelled really bad (burnt) and there is quite a bit of grey metal floating inside. The hole highlited on the last photo leads nowhere on the cover.IMG_20200606_123631.jpegIMG_20200606_124106_1.jpegIMG_20200606_124318.jpegIMG_20200606_123913.jpegIMG_20200606_125615.jpeg
