2390 Powershift diagnostic help

This forum has been a huge help and is full of a wealth of information. Hoping someone out there can help shed some light on a hydraulic problem with my Case 2390.
Just recently picked up a great running 2390. Engine purrs like a kitten. Everything was functioning for first 5 hrs use. Went to start yesterday and after reasonable warm up period, it would stall when clutch fully depressed. After several tries, it finally would allow me to clutch without stalling.
Packed everything up to road it to one of my other farms 5 miles away. Thatís when I noticed 4th gear was not working at all( no low, medium or high) Thought maybe I lost a linkage from plowing week before so continued in third gear.
Plowed about 25 acres and then things started going down hill. Did most of my plowing in 2nd gear high. When I was finishing up I noticed that 2nd gear medium and low seemed soft. Thatís when I started worrying. In 1st, 2nd, and 3rd Ėlow medium sluggish to not working at all. High gear functions normally.
My thought was problem with C-1. I checked C-1 pilot spool and it was sticking. After freeing it up low and medium seem to work a little better in some gears.
While packing everything up to road back to barn I noticed everything had gone to hell.
Here is what I have:
1. 1st gear- low doesnít work, medium works but sluggish, high and reverse works fine
2. 2nd gear-low and medium work but sluggish, high and reverse works fine
3. 3rd gear-low doesnít work, 2nd sluggish, high and reverse works fine
4. 4th gear-low, medium high, donít work(I didnít check reverse).
5. Auxiliary hydraulics do not work unless in high, and then they work very slow and only with engine reved very high.
6. 3pt does not work unless in high
7. Power steering does not seem to work at all.
Iím ordering a set of gauges to check pressures. If I have a leak in the c-1 circuit , I figured that Iíd lose both low and medium. But I clearly have medium in some gears. Low is mostly hit or miss(mostly miss). Iím thinking 4th gear is a linkage issue I just havenít found yet. Loss of power steering completely baffles me. Itís too coincident to think the cylinder gave up the same time everything else. I am also baffled as to why auxiliary and 3 pt only work in high.
Iím a decent mechanic so if I have to split and pull powershift for rebuild, that doesnít scare me. Hoping someone could point to a suspect accessible valve/junction that I should check first.
Please limit inputs to constructive feedback. I donít need a lot of ďWhat do you expect from a case power shiftĒ
I absolutely love the engine in this tractor and Iím willing to invest he time/money to get the hydraulics working correctly again.

Thanks in advance
