A plurality of self-energizing/blocker members ( ) transmit shift force applied to the shift sleeve and self-energizing force to friction rings ( ) via blocker surfaces ( ) defined by blocker members ( ) that have opposite ends ( ) attached to the friction rings. The blocker members also disengage the friction surfaces of one cone clutch prior to engagement of to the friction surfaces of the other cone.
