A transfer case includes an input shaft, first and second output shafts, and a planetary gearset including a sun gear, a ring gear and planet gears rotatably supported on a carrier coupled to the first output shaft. A collar is driven by the sun gear and selectively drives the carrier. The ring gear is moveable between first and second positions. The collar is coupled to the ring gear for movement therewith between first and second positions. The collar is operable in its first position to couple the sun gear to the carrier and operable in its second position to be released from engagement with the carrier. The ring gear is operable in its first position to be released from coupled engagement with a stationary member and operable in its second position to be coupled to the stationary member. A mechanism moves the ring gear between its first and second positions.
