Hello, I have a question.

If it was still in drive the 'engine thing' would not allow it to get above 67.
It will take itself out of gear sometimes to coast, but not to 80. That would require the driver moving it to N.

If it was in D on cruise on a very steep hill with a very heavy load it can go above 67, but that would push the RPM way past 2200. There would be over rev and over speed warning going off, so 'not noticing' you are going too fast is pretty much impossible.
Unless you went to N or have the cruise turned off.

Still, it is the drivers responsibility to watch their speed and keep it within company set limits.
Swift makes it perfectly clear what will happen if you don't.

 

You make a auto sound harder than my manual I just set a gear and let the engine hold her all the way down the hill

 

Right ...my son had a used swifty for awhile.

 

My gosh yes. All this automatic downshifting, pushing the engine into the redline, e-coast all sounds like a bunch of crap to me. Run the truck with your right foot to control the fuel pedal, and brake pedal. Left for the clutch when needed. Cruise control for more level ground. Use your dang feet, there just sitting on the floor with nothing to do. I say first 15 years of truck driving should be NO CRUISE CONTROL, for ya. ( well mayby excessive) .

 

Amen.

Plus I find that after driving an auto all day long my back and legs are much tighter because I move a whole lot less.

 

No, the only way to avoid a speed event is to pay attention.

But without having to watch speed/rpms gagues to shift, guys stop watching the gauges at all and then get surprised.

One of the fun things avout these trucks is it's "easy" for companies to change the programing. My truck doesn't kick back in gear until someplace over 70 (I forget where as I don't go over 70).

And I completly agree it's the driver's responsibility to know and follow policy. I just find it's easy to pick up unexpected speed in an auto.

I find I have to think and anticipate more in an auto as there are now 2 idiots driving the truck - me and the truck.

 

My old flatbed co. I was leased on to put those tat/tale on their co. trailers and I picked a loaded co trailer and let it get a running start going down a hill just before a hard long climb, if it rained it sent it into any where from 79mph to a reading of 35mph in a 1/4 mi. they sent me to the man behind the desk when i was turning in paper work, he said it showed a speed infraction but i pulled out my log for that day and i marked heavy rain on log that day and slipped on out door i came in thru?

 

I'm not sure what heavy rain would have to do with getting to 79 before a hill, or even why you would even note it in your log.
It had to be something you did after the fact trying to CYA.

 

Thats one item I never did with our Meritor Rockwell 2001 era auto, never never never.

Frankly the transmission was well aware and tuned to provide power to drives at all times and a few times when she left her feet followed us down through the gears and keep the power to the drives whatever happens.

Ive buried tachs before the risk is you throw the crankshaft bearings and boom for lack of a better word. There is so much going on in that situation that its impossible "Oh I didnt know shes doing 80 or whatever." BS.

The more I think about this the less inclined I would want to accomodate the OP. Maybe he got drunk on that georgia overdrive for a few minutes and liked it. Ugh.
