Downshifting without revving up the engine?

I dont think about it? I just do it

 

I don't think it does actually, If you just read it as facts.
The automated truck it is programmed in tho .That's the only part I disagree with.

 

I think we need to define when Ed was downshifting........at 1100 rpm. Climbing a hill in need of a lower gear? Rolling up to a stop sign?
The tachograph example that @REALITY098765 mentioned still requires a bump of the throttle, and Ed evidently doesn't do that.

I have never driven a truck newer than our 2000 KW, but, I suppose in this modern era the computer has the ability to automatically match the needed engine speed during a shift to properly mesh with the chosen gear at whatever speed the truck is traveling, at least within the appropriate rpm range. That would not require synchronization, but some sort of signal from the shifter to the ECM to indicate the chosen gear, as well as input from the speed sensor on the transmission. I'm not sure that exists, and the RPM would still be coming up even if not caused by Ed's foot.

Oh wait.....there is another way and I have done it numerous times. When starting out with a 5 x 4 at lower speeds you can put the main box in neutral and slap the brownie into the next gear and then mesh the main box. No, that's not correct either, we only did that while upshifting, and usually just from 1st to 2nd in the Brownie............but I don't think that was what Ed was doing.

Basically, I have not contributed one bit of usable information in this post and I apologize. We really do need a video of what Mr. Ed was doing, because like most on here I do not understand how it could be done as described.

 

Mystery solved. Ed was driving an automatic.

 

I'll try to explain it
If you are cruising at say 65 mph and you come to a grade where you need to downshift , you don't try to raise the rpm by pressing the fuel feed you just take the pressure off the drive train and the rpm will go up naturally and you slip into the next gear down at the appropriate rpm. If done correctly you right foot can stay locked.
If shifting up you just let up enough to let the rpm to drop 2-300 r's to make the shift. NO need to blip the throttle all the time.
It works floating and with the clutch ,maybe just touch the clutch pedal to take the load off.
As for advantages it's easier on the drivetrain and saves fuel.
Used to be a part of driver improvement courses.

 

so the uphill slows you down while you float the rpm until gear matches speed to slide in.

still artificially raising the rpm. That’s doable I get that but still not the same as what Ed’s been doing as explained.

 

As far as I know the op just said Ed wasn't moving the Accelerator not that he wasn't raising the rpm
And it's not artificial ,it's natural, blipping the throttle is artificial.

 

Hold the accelerator in place while it’s in neutral is still artificially raising the throttle. Natural is popping it in gear somehow using the clutch and as you begin to release the clutch engine rpm goes up because of the speed and pressure.

that’s what I mean the difference between the two.
