Slow hydraulics

I have a couple of trucks where the sideshifts are moving veeeerrrrrryyyy slow. Aux system is only running about 975 - 1000 psi (should be almost 1800). The lift/aux pump is less than a year old and the solenoid valve isn't the cause either. Anyone have ANY ideas? We're fresh out.

yep...
cylinder bypass would be my first w.a.g....
I would also be considering changing hydraulic oil and filters... as a preventive maintenance.
freezer operation?

try lifting and sideshift at same time,if it sideshifts,reach or tilts faster, that means the pump isnt running fast enough,the aux side of pump is bad
