A few thoughts about solenoids.
How is the hydraulic circuit arranged?  Are there two solenoids, one to
open (feed) and one to close (bleed)?  If not, how is the pressure
relieved to close window?  Is it a multi function solenoid? Is there a
supply line only or a supply and return line?  Does the pump run
continuously, cycle to maintain pressure or cycle with the window piston?

If the valve is not just the right capacity (Cv) it could work too slowly
or slam open and closed.  If you don't know the exact size, I would
suggest that you go a little large and pipe an adjustable flow control
valve in series.  This is just an adjustable (and inexpensive)
restrictor.  It can be adjusted for smooth operation.  It should be
available from the same vendor as the solenoid.

Inquiring mind wants to know.
