If you're loaded heavy and start down an unfamiliar grade turn on your jake, start out with whatever gear puts you 1500-1700 rpm at 30 mph. let it hit 30 then brake with solid even pressure back to 25, let it build back to 30, repeat. If that feels fine, jump up a gear and do the same thing braking 35 to 30, if that feels fine go for 40 to 35, etc... you want your top speed to always equal 1600 rpm's or thereabouts whatever gear your in and when you brake push good and solid, don't ride them, pull it down 5 mph, then let off.
If you don't have a jake and are fully loaded you may have to go as slow as 20 or 25.
I should explain, when I say "feels fine". What I mean is there is adequate time between braking to allow cooling and that when you brake you slow the truck down easily. If you have any doubt, just don't shift up. no shame in taking it too slow your first couple times. There's been more than a few who wish they had.

In driving school I was told to use one gear lower than the one used to top the hill.

A lot of newer drivers dont know how Monteagle was a long time ago. Im too young and never drove it back then but Ive seen the pictures. Ive talked to old timers about it (no offense guys). A newer guy said to me a few years back, "that Johnny Cash song about Monteagle.... I dont see what the big deal is". Thats when a couple guys at the lunch counter educated him.
OP- take it slow and dont let anyone rush you. Just put on your flashers and take it easy. Guys will get pissy with you, but they will get over it, people who fly down those mountains eventually learn that, that arrogance can get you or someone else a severe case of the Deads. I would follow Danny the truckers advice.camaro68 Thanks this. -
If I went 45 in 8th gear my engine would be screaming. I always go down it in 9th using the jake. May have to tap the brakes a little if I'm on the heavy side. Haven't smoked them yet.
camaro68 Thanks this. -
There are signs posted with varying speed limits depending upon your gross weight. Use whatever gear you need to in order to run that speed down the hill. If you're doing it right, your RPM's will be between 1500 and 1800 so that your engine brake will be better able to hold you back. If you don't have jakes, drop another gear or two and go a little slower. If you've got to touch the brakes more than a couple times on the way down, you're in too high of a gear and trying to go too fast. If you're riding the brakes the whole way down, you've got no business behind the wheel of a truck. Seems every time I'm down that way, though, I see a few trucks smoking the brakes as they fly down that hill and I'd hate to see what would happen if they came around one of the curves and found the road blocked....whether it was a wreck, landslide, broke down vehicle, etc...not a good situation to be in.
It isn't a race to see who can reach the bottom the fastest, so take your time and save your brakes in case you need them. -

I found that a lot of what they taught us in school had no basis in reality as far as mountains were concerned.
camaro68 and Blind Driver Thank this. -
Do what the signs tell you. Put it in one gear less than the speed required (ie 8th for 45mph, 7th for 35mph etc etc, on a ten speed of course) and then turn on the CB and get yelled at by the super truckers going 70 and laugh because you know that superheroes don't exist. Be safe out here drivers
camaro68 Thanks this. -
I had 40plusK paper load first time down. hit it in 8th with full jake. max 35/40mph...everyone was blowing by me. seems like there are posted speeds for going down that grade, no one seems to see the signs or just totally ignores them. I'm pretty new to otr so its prolly a bigger deal to me than to most drivers who have been out for years.
camaro68 Thanks this.
