When coming down the other side, I use the tow haul switch so that I can control my speed. When in tow/haul on my rig it will down shift each time I step on the brakes until I get to a gear I am comfortable with.
I don't know if this helps but it makes me feel better not letting the engine rev up like a two stroke.

Same with Cajon Pass but going downhill I find that not using the Tow/Haul and just tapping occasionally on the brakes works okay without the very, very high RPMs. Now pulling our Jeep Wrangler so I don't do much more than 60 on flat roads. Going up Cajon Pass I'm with you, about 45.
