Remember that to drive effectively in any mountains, you need to take care of your engine AND transmission. Learn when to downshift to both make power and keep the tranny from getting hot. If you don't have a tachometer in your vehicle, you need to install one. In order to not burn things up, learn to drive by the tach, not the speedometer. Spin your engine up to higher rpm's will keep the engine and tranny coolere.
Coming down the long steep grades, you will need to remember that lower gears and slower speeds are directly related to safety. You should rarely need to use your vehicles brakes if you are using your engine to brake.
