A torque converter includes an impeller, a turbine and a stator. The torque converter may also include an impeller clutch configured to releasably couple the impeller to a power source, the impeller clutch having a disc stack with a plurality of splined friction discs and a plurality of separator plates. The friction discs may be rotationally engaged with the impeller. Each of the separator plates has an ear extending radially outward from an outer diameter and an opening formed in the ear, the openings in the ears of the stator plates being circumferentially aligned to define a channel. A pin is received in the channel and in a recess defined by the rotating housing.
