The Donner Summit is the high point at 7,300 ft. Short compared to passes in Wyoming and Colorado. Just drive with a little more attention to RPMs and temperature gauge. When RPMs are down and Temp gauge starts to climb, DOWNSHIFT. More RPMs means engine isn't lugging and coolant circulates faster. Don't wait for the computer to downshift, do it manually. Downhill, also downshift and use engine retarder. Apply brakes firmly to drop speed 10 mph then FOOT OFF PEDAL until you need to slow by 10 mph again. Biggest issue is folks that ride the brake pedal or apply lightly and build up heat.
