A vehicle driveline component having a housing, first and second shafts supported by the housing for rotation about a rotary axis, a two-speed transmission in a power transmission path between the first and second shafts, a shift fork and a failsafe spring. The two-speed transmission has a movable member that is movable along the rotary axis between a high-speed position, in which the two-speed transmission operates in a first gear ratio, and a low-speed position in which the two-speed transmission operates in a second gear ratio that provides a higher speed reduction between the first and second shafts than the first gear ratio. The shift fork is coupled to the movable member for movement therewith along the rotary axis. The failsafe spring is disposed coaxially about the rotary axis and biases the movable member toward the high-speed position.

A method for operating a transmission (3) that includes at least one form-locking shift element (A, F) with two shift-element halves is provided. The shift element (A, F) is disengaged in a first end position and is engaged in a second end position of a displaceable shift-element half. Upon detection of a sensor malfunction, a check is carried out to determine whether the shift-element half, before the malfunction of the sensor, was in an end position as demanded and was actuated by an actuation force acting in the direction of this end position. Power flow in the transmission (3) is maintained for as long as it takes for the shift-element half, starting from the current end position, to be actuated in the direction of the other end position and/or for the actuation force acting in the direction of the current end position to be less than a threshold value.
