Automated Tranny Pros and Cons

The company probably thinks the poor truck can only handle one trip with him in the seat that's why he's got the recovery job.

You nailed it @scottied67 . They turn bad drivers into average ones therefore dumbing down the job increasing the hiring pool and lowering wage rates. Nothing personal against anyone. Just a fact is all.

 

Depends on how the truck is spec'd and how heavy it's loaded, bobtail, if I mash the go pedal, I can get wheel spin 1st, 2nd and 3rd. BTW, if you're worried about something keeping up, you're in the wrong line of work, it's not about drag racing.

 

Way too late
Way too deep
But thanks...

 

Oh... Ok... So they work just like the Autos do when in Manual Mode... Cool... Learned something new today... Thanks.

 

Close - more like manuals if you replaced the stick shift with buttons. No computer, still a clutch. Nothing to slow a good man down. Think of it as the best gear you ever floated over and over again. Then multiply that by 10.... Your welcome.

 

Yep no computers or automation here...those paddles are directly connected to the transmission behind you without a computer controlling anything....



It is true the driver requests the uplift or downshift and the transmission can't do it by itself...but a computer that needs constant reprogramming is most definitely involved

 

^^^ Well mate no need to confuse folks with all those fancy switches.

But have a look here for a computer.


No that is a shift drum. How about here?

Thats a cassette. No computer there. I know these photos are a couple years old but please forgive me if they don't invite a trucker over for a look see at the newest stuff. Not so much different though. Granted a little bit, but I doubt you would notice.

So if you going to call the stepper motor a 'computer' you got me. Because that would be the most sophisticated piece of equipment used to run a shift drum like above. Often seen just plain old levers, air cylinders, and solenoids run shift drums, but I know they are like to play sophisticated over their in F1.

Tell me what do you think they need a computer for?

 

Hehehe. Sure glad you showed up Toomany. I was gettin' bored.

 

You act as if you understand how a seamless transmission works, you are selecting odd and even gears 1-8 in this case simontaneously and changing gears in 1-2 milliseconds.

This requires a computer to ensure the two gears are not selected at the same time - the power interruption is essentially nill. I agree that the shift won't happen until the paddle is pulled, but no computer no shift - these things are in no way related to a standard manual...

And yes when that computer fails, well reboot and you may get to continue. This is why they are called semi-automated transmissions...
