4310 transmission hyd. pressure low

I have a trouble code that has led me to check transmission hyd. pressure. I have checked it and only has about 60psi when it should have 135-175psi. to engage the solenoid valves and clutch packs. Does anyone have any ideas what steps I need to take for troubleshooting?

When was that last time the transmission oil, filters, and suction screen were changed/inspected?

Thanks

That was my first thought so I drained the fluid and flushed with diesel fuel and changed all the filters. Still same result. I did notice it seemed to have some water in it.
