Automatic transmission is almost universal on big trucks operating general transport at 44,000kgs in Europe now, and we've found it makes little difference to the fuel milage of good drivers but improves the performance of poor ones
why would he choose a 7 speed automatic transmission when dd makes a 12 speed. let's make a better comparison with the gears dosen't seem like you gave the automatic a fair chance. maybe bias perhaps. 🤷🏾♂️
I think it would be a better comparison if the automatic truck had an 18 speed automated transmission but it’s still interesting to see the difference between those trucks.
Great comparison test. As real world as you can ask. I'm would be interested in the difference between the two types with respect to Transmission Temp's also. Have a good one
To me it seems obvious without doing any test. This test just proves it. I don't like driving anything with an automatic. An automatic is always a compromise.
I could be wrong but my understanding is that Allison automatics are so called "true" automatics mechanically and they are pretty wasteful with the transfer of power/torque to the wheels, the automatics that are basically standard now in Europe are automated manuals, so they should be more efficient with the power/torque transfer, and they usually have 12 gears forward and 1-2 reverse atleast what I have driven here in Finland for the last 10 years or so.
Every vehicle I have ever owned to date has had three pedals. I love visiting places in Europe because rentals default with a manual transmission. Call me old school but I just find I have serious control freak issues that a manual transmission soothes that like no other and if it saves on fuel... what a BONUS!
That Allison 4700 rds has to deal with only 6 gear to get the job done when loaded. The 7th gear is a big ratio ( 0.64) that doesn't exist on a normal 18 speed. Magic is really in the torque converter, but when you lock up here 's what you have in comparison of a 18 speed as a matter of ratios: 1H 3H 5H 6H 7H 8H. That's what the Cummins have too deal with. Normally differential ratios are higher than your friend with the w990. There's no one size fits all applications and that is a good example. Merci Doug pour tout ce que tu fait, cest vraiment intéressant. Ca donne une bonne éducation et un tres bon divertissement.
This is the video I was waiting for and finilly its here to show which is better and what are the pors/cons of the two. Glad you doing this vid. Lot of free coffee if you do some discounts. LoL
I am surprised the Allison transmission is only a 7 speed. I suspect if it had more gears and appropriate gear ratios, the difference wouldn't be as large.
that's a significant difference. For me, I like every advantage I can get, and I feel that the auto allows you to focus more on other tasks. however, that's a lot of money.
I drove a lot in snow and mountains in Iceland, doing heavy hauling. I never touched a automatic until I moved to Sweden (except for large tour buses). Call me old fashioned, but I want that extra control you have with a manual in icy and slippery conditions. I never compared with my fellow truckers in Iceland, but kinda figured the fuel economy would be worse with the automatics because they would invariably revving higher than me.

Wow! $500 difference for a 3 or 4 day trip is pretty significant. Just think of what it would amount over the course of a year.
I'm interested to see what the difference would be if they had the same amount of gears.

Hellova’ lot of Tim Bits.

Good info. Good channel.

I already kind of knew the answer just never saw it demonstrated before. Thank you.

Another great video. Thanks.
Another very interesting video withal life experience and factual info.
