You can think of a four-wheel drive transfer case as though it were a two-speed transmission with an extra output. Engine power normally goes through high range (or second gear if you think of it as a transmission) in a 1-to-1 ratio. Low range is the transfer case's "first" gear. Power normally flows directly through these gears and out the back of the transfer case, but shifting it to 4WD engages a clutch that sends engine power to a second shaft that drives the front wheels as well.

Shifting the Transfer Case

Step 1

Start out with the transfer case's gear selector in the "2WD High" position. This is your standard driving position.

Step 2

Shift to "4WD High". Many older transfer cases require that the vehicle be at a complete stop when engaging 4WD. However, newer "four on the fly" transfer cases generally allow you to engage all four wheels at any speed.

Stop the vehicle and shift into "4WD Low" when you need to overcome obstacles on the trail or pull a heavy load at low speeds. Many transfer cases offer a gear reduction of between 3- and 4-to-1. You'll have about three to four times the power, but that extra grunt comes at the expense of a very limited top speed: about 20 to 30 mph in most cases.
