Good afternoon and welcome to JustAnswer!!
My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.
If you have a All-Wheel drive then yes you are in 4wd all the time, and to select 4WD low you will need to move the shifter as you don't have 2WD mode.
The NV244 is an electronically controlled full and part-time transfer case with no two wheel drive operation.
A differential in the transfer case is used to control torque transfer to the front and rear axles. A low range gear reduction system provides increased low speed torque capability for off road operation. The low range provides a 2.72:1 reduction ratio.
The geartrain is mounted in two aluminum case halves attached with bolts. The mainshaft front and rear bearings are mounted in aluminum retainer housings bolted to the case halves.
NV244 operating ranges are:
- AWD(All-Wheel Drive)
- 4HI (Part-time)
The AWD mode can be used at any time and on any road surface.
The 4HI (Part-time) and 4LO ranges are for off road use only. The only time these ranges can be used is when the road surface is covered with snow, ice, or other loose slippery material
If you need anymore assistance feel free to reply and don't forget the RATING before leaving the site!!
Have a great day,
