Why do you say if its a diesel gearing down wont help? Down shifting my diesel holds me way better than any gas truck ever has. I can go down a 6% grade and simply pulling it out of overdrive or down to second will maintain my speed with my fifth wheel
If it does as you say. then it has some sort of after market exhaust, or engine brake or trany brake. diesels by design little to no engine braking in their natural state. Why? Because while they have tons of compression on the front side. All they have on the back side is a great big open hole. Nothing to create back pressure.
That is why Exhaust brakes were invented in the first place. To give engine braking to diesels, because they didn't have any. Having driven the big trucks. I learned the hard way. Diesels in their natural state, free wheel down the mountain, in any gear.
