A vehicle driveline that includes a differential assembly, a two-speed transmission, a power take-off unit, a range sleeve, a mode sleeve and an input shaft. The range sleeve is non-rotatably but axially slidably coupled to the input shaft. The range sleeve provides rotary power to the two-speed transmission and is movable into different positions to control the gear ratio in which the two-speed transmission operates. The two-speed transmission outputs rotary power to the differential assembly. The mode sleeve is selectively movable into a position where it transmits rotary power between the range sleeve and a PTU input of the power-take off unit. Movement of the range and mode sleeves can be coordinated to provide a two-wheel drive high speed mode, a four-wheel drive high speed mode and a four-wheel drive low speed mode.
