Auto on transfer switch case?

On the switch, there's 2 wheel drive, 4 high, and 4 low. Then some models have an auto among the selections that functions like an all wheel drive. Look on your switch to see if there's an auto option

if it helps you understand the transfer case at all, I wouldn't drive around town with my transfer case running. It's job basically for a 4WD is that allows both axles to be controlled by differential connection. And it also eats your gas pretty good, too. Keep in mind, took, when your case is activated and the front diff is controlling that axle, it also prevents your from turning sharp turns. good luck
