Case C-O-M mechanic needed

I recently repaired a c-o-m in an 830. The tractor had no pull at all after disassembly I found the 3 screws that hold the keys in the clutch pac had broken allowing the keys to come out damaging the clutches & plates. After replacing 2 clutch plates & a drive plate & drilling out the screws,checking clearances &replacing a couple seal rings I got it back together and the tractor pulls much better and can work but it ain"t right. It loses pulling under load in high gears and will "bogg-down" in low. There is 310# of pump pressure, 140#of clutch pressure, and zero pressure from the TC.
I am trying to understand what is happening and the flow to the converter.
If any one knows or might know whats happening please drop me a line.
 
Hows" that gonna help? Dont know if thats possible. Take the pump assey off and fill the pick-up tube& pump with Lucas 80w oil? What will that do? Theres already enough pressure there. Explain a little more please. Thankz
 
Don't use 80w. First off what gear are you trying to pull in, have you tried putting it in direct? You should be using hytran or better yet a good grade of atf. Will try to attach a picture out of manual.

I use a preamium TCH compatible fluid. Direct Drive does work but the tractor will loose momentum in any gear if pushed and a lower gear must be used. It does pull a 2-bottom ok untill it comes to a heavy spot even DD doesnt help I have to pull the plow up to move it. In 6th on the road it has problems on slight rises.
My concern is the excessive pump pressure and the zero converter pressure, its as if its restricted or blocked some how but I don't know.
My TO-35 will out pull it, at least it will spin the wheels pulling.
