I pulled my manual.. (you got me thinking about this situation)...

I have the 5 speed tranny on a 2007 chassis. Page 183-185 covers driving/trans operation for my tranny. The way I read it, I should stay in "D" with Tow Haul and work the brake to stay at a safe speed.

Link to the manual that I've been using:

Truckers rule of thumb "whatever gear it takes to go UP and whatever rpm you run in that gear, that's the way you come down. Example : it takes 2nd gear and the best rpm you can get is 2500, then you come down in 2nd gear. When the rpm gets to 3000 rpm, use the brake to get rpm to 2000, then let off brake, (so they can cool) and let rpm build back to 3000. Then brake again, etc., etc, until you reach bottom. Keep your rpm 500 above, then brake until 500 below, what it would take to pull the same grade. Sometimes this must be done by trial, especially if you haven't pulled that hill. You can time how fast the rpm's build, and if it's too fast, ie the brakes don't have time to cool, then you might need a lower gear. If it's too long, then you might need a higher gear. If you are on the brakes 15 seconds, then you need to off of them for 15 ~ 20 seconds. Speed adds another factor, that may require a different gear selection. The idea is to split the braking required , letting the engine/trans do half, then letting the brakes do half. Hope this helps.

By the way, couldn't get to your link, error said I must log-in.

Sorry about the link...

Try this:

Then put in your year, Ford, and the closest match. For me, I used the F-550.

Thanks, now that I've seen the manual, sounds like TOW/HAUL will work most of the time. Again will depend on the grade and the weight of your rig, and the speed you feel safe running. I usually use the posted TRUCK speed as a guideline, and try not to exceed it by much. I don't have tow/haul on my F150, so I manually select a gear, usually at the top of the hill or just before, while still going slow, before things get out of hand. Also good to be down a gear or two at the top, in case you made a wrong selection, your brakes are still cool and you can get slowed down enough to select a better gear. One last thing, don't worry about the traffic behind you or the horn blowing. They'd really rather be going slow than not at all if you spill your rig all over the road. The horn won't hurt, and neither will the gestures. I even enjoy being shown I'm "number 1" sometimes. (hope we can all laugh at this).

Hey, the government has used a lot of your tax dollars turning me into an a$$hole and I'm proud of it. I take it as a compliment. In my line of work there is no room at all for ambiguity and therefore I say it as I see it.

I will proudly stand along side ya windrider...

Again...my surprise was the inability of the V-10 engine to provide enough engine compression to keep my unit down to essentially a slow crawl! On the Steamboat Springs downgrade, I had the transmission in low (first) gear...and the transmission never tried to upshift (and I wouldn't have wanted it to). I wanted to keep the speed down enough so that I would have time and enough braking left to pull over and stop if I had to. Some people were passing me, going downhill, at least 70mph and I could hear their tires squealing on the curves! My nephew (a truck driver) was with me and cursing my V-10 engine and kept saying "see I told you, you should have bought the diesel with a jack-brake!"
I was once in Wyoming following a TT being pulled by a small pickup and they burned out their brakes on a long downgrade. They said that they had down shifted to first gear and the combo kept trying to break the speed limit in first! They decided that
they would stay in first even if the trans burned out. Everytime they upshifted to second, the combo wanted to shoot ahead. They thought that they were going to go off the road.

Sounds like you've got a bad combo. Sell it and go with a diesel since that's what you'll trust. You probably were going too fast to actually be in 1st gear. My bet is the computer upshifted for you. You won't answer my questions so I'm guessing you don't like the answers.

Assuming that, you probably didn't have Tow/Haul on and you probably thought the engine was "overrevving" because it was too loud for what you thought was safe. My guess is that you haven't read the manual and probably won't. Please sell the rig before you wrap yourself around a tree and blame Forest River. You could probably sit on that hill all day and watch F53 chassis come down it without a problem.

Happy trails!

Tsunami, it's not just the V10, it's ALL gas engines. I have never driven an RV yet with a gas engine that WILL hold you on a 7 percent grade! I'm not even sure a diesel would do it either unless it had a jake brake. I really don't know why you expect the V10 to do it. Our Chevy 454 in the last rig we had would warp it's exhaust manifolds to the point of letting the exhaust gas burn through the spark plug wires if you tried to use compression only to keep your speed in check.

It comes down to the fact of proper driving technique as eluded to by Windrider and Steve. It is the reason why you see large semis on steep passes doing 10mph down hill and using their breaks prudently to keep their speed in check and the engine from over reving.

I think you have unrealistic expectations. There are several of us here driving MUCH bigger rigs than yours with the same engine without problems. I suggest as the others have to read your manual and learn to drive your rig correctly.

It also sounds like those folks in Wyoming had a truck too small for the trailer they were pulling, that's not the trucks fault but unfortunately it's a condition we see all to often on our trips. Rigs overloaded, guys pulling full size SUVs with their motorhomes that are probably at least 1500lbs over the rated tow capacity of the motorhome, etc, etc.

I was trying to relate my surprise concerning the action of my V-10 rig on a steep grade.
Rather the responses I received on this forum were "shut up or go out and spend another $20,000 for a diesel"
I guess that I will shut up...I certainly don't want to interact with the people who seem to populate this forum!

Might be best for everyone. Folks here like to ask questions to get more info so they can advise you. We provided you a link to the manual, offered ideas about Tow/Haul and suggested that being in 1st gear may have been wrong. Given all of this feedback, the premise of your question about redlining in 1st gear is probably wrong.

Since you won't provide any feedback other than to talk about someone unrelated guy and his travel trailer and your buddy that wants you to have a "jack brake" (btw it's called a Jake Brake), your probably not a good fit for this forum.

Link regarding the Jacob Brake in case you're interested:
