Driving an automatic on icy roads and taking off on hills?

Was way more fun before they ran the jersey barrier all the way down. I remember the first time I went up it all chained up and had nothing but air to stop me if things went south and I slid backwards.

 

Seat belt off n the door open?

 

We can disagree and I probably won’t change your mind also. I don’t have numerous times I had to recover from a slide or jackknife . That’s why I would say my way is safer. That’s kinda my point you or anyone Is better off if we can avoid getting to the point of actual slide or jackknife. You are letting the trailer push your tractor downhill when only using the engine brake. That’s not a good idea,

Here is something else to think about if your are correct Freightliner made major mistakes with the D12 transmission because it will downshift automatically and raise engine rpms. Maybe Freightliner is correct when they also say don’t use engine brake in snow or ice.

 

But the wind isn’t going to cool the object any cooler than the air.

 

I get the point you are trying to make but what air?
If a running motor the air around the engine is giving off heat and wind will bring that air temperature down.
So it depends on the temperature of the air around the object.
If the sun is shining on a black object then wind could affect the temperature of the object,
So, it depends. and yea ,windchill doesn't affect inanimate objects in a controlled environment.

 

As far as traction on ice::: It's 0 degrees f. out I think I'll go out and lick a metal pipe.

 

@Oxbow I guess we will have to accept that everyone who runs the skinny mountain roads regularly have been doing it wrong all along because Freightliner says not to do it.

The old timers that taught me how would also turn the air off to their pup if the roads were bad and I suppose that’s not in the instruction manuals either.

I won’t take mountain advice from someone who hasn’t spent a lot of time honing their skills in the mountains or any line of work for that matter.

 

I have spent a lot of time honing my skills driving the mountains. You would think someone driving mountains on the back roads would know also. Especially if they had many time they had to recover from sliding . Yea even freightliner knows not to use engine brake in snow or ice.

 

I graduated High School in Grangeville, so the Harpster grade is something I thought I was intimately familiar with…… until I went down it in the semi for the first time this summer. Hoo-boy, that’ll separate the men from the boys!

 

Ok. Like I said, I learned from those that do, not those that write manuals. Running the interstate and running the backroads are two different things. Multiple people that have explained why your way isn’t the best in certain situations and you won’t hear it. I must’ve missed where you replied how much experience you have off interstate in western Montana and north Idaho. Your way works for you and that’s great. Your way isn’t the best on steep curvy roads at 105k gross.

As far as your transmission, if I were in your shoes I would know and anticipate a downshift so I would hold it in gear so that it wouldn’t downshift, but that’s just me.
