Attached to this knob we find a ZF manual 9 speed as used in various smaller (commercial) trucks. So how do we get nine gears out of this?
C is crawler, a kind of emergency super low gear that you only need for extreme starts. Often as not you only need second to start, then you can change direct to fourth. Having got successfully to this point things become a little complicated. You press the clutch and engage neutral, release the clutch, slap the lever firmly to the right (the less politically correct call this the "bitch slap"), press the clutch again and go back to first, which has now magically become fifth because you're now in high range, and you proceed all the way to eighth. Why can't you get ten gears out of this, seeing as you have a five speed base box? Because crawler in high range isn't a viable gear, it would be lower than fourth.
Complicated? Next time I'll proceed to 12 gears, which we can obtain by more than one method, and thence to 14.

Is this one of those shifters from Fast and the Furious?

I saw a video of a triple-stick truck with 19 or so gears. Looked confusing as hell at first but quickly made sense. Looks like fun.

Nope, real genuine one.

I'm beginning with simple complicated gearboxes. Complicated complicated gearboxes come later.

You have decoded it all!
They use truck transmissions so that they can handle all that NOS power! And that's why they need to double clutch! To get to the high range!

That's crazy awesome! I've driven Eaton Fuller 9-speeds before, but they're pretty simple since it's really just a 5 speed pattern with a "hi-lo range" switch.
I found a website a while back with some downright odd shift patterns, if you're interrested: http://www.chevyc60.com/the_transmissi…

ZF do their range change with switches too, but I thought the "bitch slap" was more interesting.
There are some very odd gearchanges out there.

Looking forward to it. Like Rock Bottom said earlier, the transmissions in North America use a hi-LO switch but they can also come with a splitter used to split each individual gear between shifts.

What in the ever loving bit of sorcery is this? besides a headache, and someone never being able to steal it w/o the diagram?

do you slap to the right again to get back into the low range?

I just know it came from something with this logo.

No, you reverse the process - slap left.

Question: Are most commercial vehicles in the US (like semis and school buses) manual or automatic?

I understand - not being in America - that your trucks are mainly manual at the moment while buses have automatic boxes. Trucks are in the process of automating, something that's well underway in Europe.

Depends somewhat on age. Buses in any kind of local service, typically auto. Long haul trucks used to be typically stick, but I think most new models if not all are auto. A lot of industrial trucks, dump trucks, etc. of moderate age are still stick.

Trucks are all manuals I believe. I think older school buses are manuals with the newer ones being autos but not 100% sure.

No, they sell automatic transmissions for class 8 trucks. Allison makes autos that are similar to traditional automatics (torque converter, clutch packs, planetary gearsets) but Eaton also makes trannies that are basically automated manuals.

School busses are more commonly automatic. But they are also in a different weight class than semi trucks.
Semi trucks can be had with both automatics and manuals. There are 2 different types of automatics available. The first is your traditional torque converter, clutch pack, planetary gearsets like most automatics in cars. The second is an automated manual. This is basically a manual transmission that has had the clutch and gearshift mechanisms replaced with actuators.

Thanks for clarifying that. I always thought it would make life alot easier for truck drivers to have automated manuals like with a paddle shifter setup that way they could still select the gear they want, but not have to bother dealing with overly complex shift patterns.
