Zusammenfassung:	An apparatus (100) for engaging a hydraulic clutch (102) has a varying control volume in response to an engage signal. The apparatus comprises a solenoid (106) with an armature (204) and a coil (202), and a control valve having a spool and being connected between a source of pressurized hydraulic fluid and the clutch. The spool is connected to the armature and is movable between a no-flow position and a full flow position in response to the movement of the armature. Control means is provided for controlling the spool via the armature in response to a voltage condition of the coil and an end-of-fill signal.
