Clutch apply cavity air bleed

A transmission comprising:

• a stationary component;
• a rotatable component configured to rotate relative to the stationary component;
• a selective coupler having a plurality of friction discs selectively engageable with one another, an actuator element axially moveable relative to the stationary component between a disengaged position in which the actuator element is spaced from the friction discs and an engaged position in which the friction discs are engaged with one another by contact with the actuator element, wherein:
• a first fluid cavity is formed on a first side of the stationary component,
• a second fluid cavity is formed on a second, opposing side of the stationary component and between the stationary component and the actuator element,
• such that a fluid flow from the first fluid cavity to the second fluid cavity is operable to urge the actuator element into the engaged position to rotatably fix the rotatable component relative to the stationary component;
• and
• a disc biasing member urging the friction discs to disengage from one another;
• and
• a check valve assembly for controlling a flow of fluid in a transmission, the check valve assembly comprising:
• a housing including a first chamber and a second chamber, the second chamber fluidly coupled to the first chamber and arranged axially of the first chamber along a first axis of the housing, the first chamber and the second chamber defining a fluid passageway of the housing;
• a biasing member supported by the housing for axial movement along the first axis, the biasing member configured to actuate prior to actuation of the disc biasing member of the selective coupler as a fluid pressure of the fluid flow increases, such that fluid flow from the first fluid cavity to the second fluid cavity actuates the valve element of the check valve assembly before actuating the actuator element and the plurality of friction discs;
• a valve element positioned within the first chamber and axially moveable in a first axial direction along the first axis to a seated position in which the valve element is contacting a seating surface of the first chamber and moveable in a second axial direction along the first axis, opposite the first axial direction, to an unseated position in which the valve element is spaced axially apart from the seating surface;
• and
• at least one swage extending radially inwardly from an interior wall of the first chamber, the at least one swage configured to limit axial movement of the valve element along the first axis in the second axial direction.
