It actually kinda makes sense if you’re looking at what is essential here. They probably don’t start at 1 they probably start at 3 Then hit 7 then 12 Then 17 then 20. Anything in between is that granular torque curve sweet spot for whatever reason they require it maybe if they are way overloaded or had to stop while at capacity while going uphill.

Finally found the Dominic Toretto’s gearshift.

Thought it might be legit until I saw the shift to 9th

for a moment i thought this was loss

Also is this for real? Never looked into truck transmissions or even just thought about them in general.

The real shift patterns are like this:

They look complicated but it's not too bad when you get used to the idea. In normal use it's basically a four speed H pattern with two different ways to increase the number of gears. You have a range selector to give you 8 main gears (you shift 1 through four in low range then flip to high range and move back to 1 position to give 5 through 8) and then you have a splitter that gives every gear a high and low ratio (in order you'd go 1st low -> 1st high -> 2nd low -> 2nd high -> etc). Normally you don't need to use all the gears so you can skip some of the sequence - particularly when lightly loaded. Lo position is a particularly low ratio, and reverse is as per normal except you can split it to have a somewhat faster or slower reverse gear.

I'll admit I haven't driven a full 18 speed but I've driven 9 speeds with a range selector and a 10 speed with a splitter and both were easy enough to learn so combining the two doesn't seem as daunting as it might be to those who haven't tried either.

I couldn't get the double clutching timing right, and my instructor was a cunt who got on my nerves the whole day of training. Also because they're a gated gearbox, you're supposed to follow the H pattern and not cut desire paths.

that kind of makes me disappointed

If it helps the real version is still pretty cool, with basically two transmissions and switches on the shifter

[–] CreatingMachines@fedia.io 4 points 12 hours ago (1 children)
  • wait, 2 transmissions as in 2 separate transmissions? Or like 2 working together?
[–] lka1988@lemmy.dbzer0.com 8 points 12 hours ago

Two separate gearsets in one case

[–] ThatGuy46475@lemmy.world 5 points 12 hours ago

It’s not for trucks it’s for the fast and the furious

[–] mazzilius_marsti@lemmy.world 15 points 15 hours ago (1 children)

might as well skip 5th gear

[–] tonyn@lemmy.ml 11 points 15 hours ago (3 children)

You have to go through 12th to get to 6th

[–] mazzilius_marsti@lemmy.world 2 points 3 hours ago

yeh RPM gage be like "wtf is going"?

[–] elvith@feddit.org 6 points 14 hours ago

You can go around through N, though

[–] Joelk111@lemmy.world 2 points 11 hours ago

Nah, you can go up between first and second, then to the right.

[–] distantsounds@lemmy.world 4 points 15 hours ago

Shifting from 12th to 13th as a treat

[–] Little8Lost@lemmy.world 1 points 11 hours ago

Does it even fit the community?
At least it looks more serious that the meme/shitpost ones
