Abstract: A transfer case includes an input shaft, first and second output shafts and a planetary gearset having a sun gear, a ring gear and a pinion gear meshingly engaged with the sun and ring gears. A range actuator includes first, second and third range sleeves abutted in series being axially translatable between a first position to provide a drive connection between the input shaft and the first output shaft, a second position providing a direct drive ratio connection between the input shaft and the first output shaft as well as the input shaft and a second output shaft, and a third position to provide a reduced speed drive ratio connection between the input shaft and the first output shaft as well as the input shaft and the second output shaft. The gears of the planetary gearset are not driven when the range sleeves are at the first and second positions.
