An informative video from MadMatt 4WD. A HUGE difference in brake temperatures by changing the way you do a hill descent in an automatic. Over 200C (392F) degrees cooler descending the correct way!

Mad Matt takes about saving brake pads and rotors but it also means you do not cook your brake fluid.

For me a timely reminder as I always did this in the manual Nissan Patrol, I need to remind myself to do it in the auto Grenadier - now that I own a van. The only twining I have done so far, was a flat terrain.

The same methods used with earthmoving and haul trucks with powershift and auto transmissions. They may have engine brakes like Jake's or exhaust brakes to assist but the key is to select the correct gear for the descent one gear lower than assending the incline and keep the engine rpm high to get better engine braking.
The other thing not mentioned but can be noticed and we see on trucks is that on long steep over 10% descents with tight turns at full GVM the front tyres cop a flogging and in some instances tyre pressure and temperature will increase quickly if the speed is too high.
