Eaton 10spd. Crawler gears?

You will in time. Eventually.

Interstates are built for 70 mph passenger car physics and 7% Grades generally. When you get off interstate and onto certain areas then you will find 10 and beyond. There is a difference between 7 and 15% 15% the end of your trailer is a certain amount of feet below your tractor and you cannot risk stopping upgrade because restarting is very difficult loaded. Beyond that if something broke on even steeper pulls well. All you can hope for is to stay where it is at that spot and not fall backwards off the mountain.

Anyone can get uphill. But it's the getting down that will separate the boys from the men.

 

some of the bigger hills i been down was in pennsylvania ... theres one highway i forget if its in west virginia or pennsylvania, anyways, the speed limit for trucks down this hill is 10 mph, it winds thru the mountains. no idea what grade it is but i would say pushing 12 - 13%, cool slow drive on a nice day, i wouldnt go near it with snow or ice.. i from out west but i didnt get to some narley hills till i went to pennsylvania

 

Oh dear misunderstood CC yer driving an automatic! Allison is the best Eaton not so much but we had a driver "crawl" into stopped car ahead 'cause wasn't holding down brake hard enough.

Good luck with those mountains . . .

 

Oh now Heavy, a 936 was a 3cy machine. It would probably struggle lift an empty 7 cy bucket.
