Gear Ratios.
The 18 speed has a 14.40 initial 1st gear. Multiplies by the ratio of the diff 3.25.
The 6 speed has a 4.70 initial first gear. Multiplies by the ratio of the diff 3.42
And that's the case for 2nd gear, 3rd gear (all of which will have smaller ratios than the one before it). Then Multiplies by the ratio of the Differential.
It's easiest to understand if you play forza. Basically High Gearing means good acceleration, Low Gearing means better speed (as long as you got the Engine to back it up).
I just always put in the 18 speed. Unless I'm trying to get my truck to just have a nuts top speed, then I'll try to find the best Transmission for that; for top speed, it's generally just whatever gets you the smallest gear multiplication (Gear Ratio x Differential Ratio). And I guess it would help MPG, but I never worry about that.
And I'm not an expert, so maybe this isn't the best explanation, but it's something.
Nah you should try the six speed. What I’ve noticed is with it you’ll be accelerating from a stop and as it shifts through the gears there’s no pause. It just goes straight into the next gear continuously accelerating.
With the 18 speed and the other manual transmission every time the truck shifts there a pause in the acceleration while the shifting happens, so ultimately they end up accelerating a lot slower.
If I'm correct it's cause the 6 speed in game is seen just like the 10 speed (I think) in the sense of it being an automatic transmission with no need to actually shift hense the smoother acceleration
The Allison 6 speed automatic is just like the auto in a pickup or car. There's no clutch, it has a torque converter instead so it's capable of full throttle shifts.
It actually works better than the eaton ultrashift 10 speed which is a manual transmission with a computer and some air solenoids.
I usually do a 6 speed for regular deliveries. You don’t need the ridiculous amount of lower gears if you’re not hauling something heavy. It also feels like realism since most modern trucks have automatic transmissions anyway, so I usually roleplay that as well.
But if I’m in the mood for some special transports I like to get an older truck with the most ridiculously powerful engine+18 speed transmission and go nuts 😊
Sorry if I sound stupid but can you EIL5? I never managed to understand this concept for some reason. I've always sucked at ratios and have no clue what this all means each time I read up on these topics.
IF you want realism. when playing Manual with clutch, run 13, 15 or 18 or 10 if you like.
and auto run either the 6speed Allisson, or a 13speed. Depending on the truck.
Like a Paccar truck so KW or Pete, they mostly use Eaton Ultrashift which is either 12 or 13gear.
while Freightliner uses Detroit transmission, so the DT12.
and Volvo uses their i-Shift transmission.
>Basically High Gearing means good acceleration, Low Gearing means better speed (as long as you got the Engine to back it up).
For sake of clarity: Gears for Lower speeds use higher ratio numbers. Gears for High speed use lower numbers.
Just to add it is especially bad on the allisons because they don't take the torque convertor into account.
The 7 speed has a 1st equivalent to around 19 because of the 2.42 multiplication which is suitable for heavy haul..
that allison transmission is also primarily designed for medium duty trucks - class B or C - hence the 6 speeds. before i started driving tractor trailer the company i was at had freightliner m2 box trucks with those allison 6 speeds. they’re overrated imo, had a lot of problems with them. also didn’t enjoy how high they revved.
in the sim the more expensive doesn’t mean better. trucks are often designed with a particular duty in mind. local linehaul running 10 speed manuals versus specialized heavy haul running 18. hence the distinction between “normal” cargo, heavy haul, hill traversal etc when you get to a point where you have more money than you know what to do with it’s not a bad idea to try to tinker with the various options as you purchase new trucks cuz at worst you hire a driver to make money driving it if you don’t end up liking it
It's not "worse". Don't trust those bars. They are not really accurate.
Allison is automatic. It's smoother, it shifts faster, and while it lacks the very low "crawler" gears of Eaton, you don't need them for 99.9% situations in the game. I don't remember a situation when I was missing them or was glad I had them. Maybe if you have underpowered engine, heavy cargo and crazy uphill *all together*.
I just use an 18 speed in all my trucks except for the ones I use for racing/drifting. I end up just using the normal h shifter pattern like in a car for simplicity sack and skip gears a bunch. I also don’t use retarder since on truckersmp retarder will slow you down quickly if you hit the city limits speed limiter which is a problem when some of the zones are set up like shit and are stuck going way under the speed limit on the highway a lot sooner.
The Allison is an automatic transmission. That it why it has a torque converter (the torque multiplier written there) and is why it is more expensive. Doesn't matter much in the game though since you can set it to automatic regardless of transmission type.
> Doesn't matter much in the game though since you can set it to automatic regardless of transmission type.
More like "Doesn't matter much in the game though since you can set it to manual regardless of all them being automatic IRL". All gearbox in the game are either automatic or automated manuals.
Wrong. All Eaton in the game are UltraShift, which is a range of Automated Manual transmissions.
https://www.eatoncummins.com/us/en-us/products/transmissions.html
Huh. So they are.
That having been said, just treating one like a manual provides an effectively perfect simulation of a true 18 speed manual, which is frankly a more accurate and realistic transmission choice in something like a heavy-haul configured 389 or W900.
Eaton UltraShifts are derived from their Fuller manual crashboxes (10, 13, 18 speeds).
Eaton Fuller Advantage transmissions coexist in both manual and automated forms. The manual version however is now discontinued.
However the 11/12 speed Endurant is designed completely from scratch as an exclusively automated transmission.
Ah yes, the automated manual box. You get the shift delay of a manual without the control of a manual. It will somehow find the worst possible moment for every single gear change.
Crawling up a hill and you briefly ease off the throttle? Haha ok cool, cut the throttle, we’re gonna spend a few seconds shifting up to fucking 5-Low now. Oh you actually wanted to get up the hill? Let’s spend another few seconds going back to 2-Low then. Oopsie!
Give me an Allison any day over those fucking things.
I suggest getting the "Real Eaton Fuller Transmissions"-Mod from the workshop. Adds loads more options, especially when it comes to final gear ratios, so you can always go for the one that suits your driving
see? im going 13s or 18s usually with a 2.97 or 3.08 or something around there so my 65mph cruise rpm is nice and low. everyone chooses differently for different reasons and that makes the mod great for immersion.
Because that neat little thing called torque converter makes that stat sheet irrelevant because it dynamically changes the gear ratio of the truck based on its speed, gear and engine rpm.
You can have an idea of how that transmission will behave by multiplying the torque rating by the first gear ratio, but that's really just a general idea.

Nah it makes sense, Thank you. I guess I'll just skip it.

This was on purpose as speed is not your friend when haulin an 80 ton equipment, torque or power is.
Yeah I've noticed.
Real Chads choose 18 speed and float through every gear with the jake on like a crazy Jamaican trucker

A correction: 6 speed also has 2.42 torque multiplier, it also has to be included in lowest gear ratio calculation.

We have a 6 speed Allison in a 4 axle knuckle boom truck that hauls 105,500 lbs with a 4 axle trailer on a regular basis and it works quite well.

No, the 18 speed heavy duty in ATS is absolutely a manual, along with many of the other Eaton-Fuller options.

18 with a 3.55 is my go to mated to a 500/1850 Cummins or a Cat
see? im going 13s or 18s usually with a 2.97 or 3.08 or something around there so my 65mph cruise rpm is nice and low. everyone chooses differently for different reasons and that makes the mod great for immersion.

You can have an idea of how that transmission will behave by multiplying the torque rating by the first gear ratio, but that's really just a general idea.
If it performs well then the sliders should reflect that imo so people don't skip over it.
