    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.

              @SaneMartigan
              Impressive — unsynchronized gearboxes are no longer manufactured, in the EU will it soon be nearly impossible to get a driver’s license for a manual transmission.
              I need to reallocate 🙏

                They’re going out of fashion here too but it means there’s a heap of cheap old trucks available. With our housing cost issues, I’ve been daydreaming about building a house-truck of sorts.

    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.

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