Tractor Repair: Case IH 885, clutch pack, pressure gauge

Question
My MFD quit while I was plowing. Checked all electrical and it is fine. Checked and replaced electric over hydraulic solenoid. Still nothing.Doped transfer case and took apart the clutch pack and the clutches are fine. Doped plate for the TA because they are on the same line to see if anything was leaking to drop the pressure and everything looks fine. All lines and ports are open and the TA was still working. I am out of Ideas.

Answer
You have to remember that it is a electro/hydraulic released mechanically engaged mfwd to make sure the power and ground are good to the solenoid. When you changed the solenoid did you change the spool to or just the coil? Pressure gauge is the only way to go. See what you got and we will go from there.
