Abstract: A dog clutch operable to bypass a variator of a transmission is disclosed. The dog clutch includes a housing engaged with an input ring of the variator. The dog clutch also includes a piston engaged with the housing and movable from a first position in which the piston is disengaged from an output ring of the variator to a second position in which the piston is engaged with the output ring. The variator input ring and output ring are locked together when the dog clutch is in the second position to prevent the variator from producing continuously variable torque output. The variator is operable to produce continuously-variable torque output when the dog clutch is in the first position.
