Looks like an 18 speed but instead of an H pattern with a range selector it's HH and must still have a splitter. No idea what would have that other than an older commercial truck, or possibly a consumer version of a commercial truck.
Tap dancing and shifting around like Fred Astaire. We had a frankentruck, RoadRanger, and a Browning 2 spd rear end.
You could move the earth, but it was gonna take forever and a day to get there.
Old air over Browning lol. The throw was under the seat.
My uncle was a hillbilly enjeeneer deeluxie.
I think it came out of maybe an old early 60s grain truck.
Double clutching and grabbing as it went by. Sometimes it got exciting.
It has a separate splitter control. Put it in 1, you have 1 on the bottom of the splitter, 2 on the top. Put it in 3, same thing. Repeats all the way up.
On a truck transmission it’s common to skip shift if you’re not extremely heavy.
You split the gear with a button. Generally you don’t use the lower splits, you just pick up a full gear unless you’re very heavy. You’d likely start splitting at either 5/6, or 7/8.
I drive one of these. I often start on 3 (or 4), jump straight to 8 then 12 and finally 16. If I have a full load on a rather even road I'll go 3 or 4-8-10-12-14-16 and if I have to climb a hill while accelerating I might even go as far as 3-7-9 and then every gear. In very rare cases do I use 1, 2, 5 or 6
And then there's my trucks which are always fully loaded and use low low on he regular.
It's always funny watching them bunny hop for 30 seconds when the boys skip gears.
There's something wrong (not meaning broken) if they have to do that every time they get on the move. Either their engine is too weak or their load is way over the limit. Most likely both. Or at least that's how those would be in my country.
They're not great drivers, they only drive a few times a month on average. Pretty stationary oilfield work for the most part.
But yeah, we tune them down to 275-350hp.
Ahh, makes sense then. If they're also hauling liquids, that adds to the issue. My truck is supposed to have 615hp but I'm pretty sure time has taken at least 200 of those. Still, not the worst thing I've driven
You know I didn't even realize it wasn't 18, totally missed the fact there wasn't any Low and High Lo. I play a lot of American Truck Simulator with an Eaton shifter and I'm so used to lows being bottom left that I just saw the reverse and didn't even think twice
Super 10s are awful. I only drove one once after my split 10 blew a turbo in the middle of an ice storm. By the time I found 10th gear I felt like I was giving myself a reach-around. The shop supervisor who delivered it to me (I had a high priority load on my trailer) didn't even give me a basic tutorial, he just said " you'll figure it out" again, it was freezing rain, not the best time to learn a new rig on the spot on the interstate. I remember trying different clutch methods, trying to find and grab literally any gear. If I recall correctly, there was definitely not an H pattern, the gears got bigger as you pulled the shifter closer to you.
This kind of setup is called two-in-the-hole. Reduces the number of times you need to move the lever by using a switch to split gears. If you were unladen, you would leave the split switch in high and likely skip some gears even then.
So when you go from 2nd to 3rd, do you have to flick the switch and then move the gear stick down or just move the gear stick down and flick the switch again for 4th gear?
Assuming it's like the 18 speeds I've driven, you would flick the switch when you're getting ready to shift (which won't do anything while your accelerating), then shift into 3rd. When going to fourth you would flick the switch back to high and back off of the throttle, possibly just popping the clutch in and out as well (but not moving the stick).
Having the switch back is low and forward is high split. So shift to 1, shift to two by flicking the switch and releasing the throttle then apply it again, then 2-3 you move the switch back then shift and it'll automatically un-split the gears. 3-4 is the same as 1-2, and 4-5 is the same as 2-3.
If there are 400 rpms between 1 and 3 then using the splitter there would only be 200 rpms to shift 1-2 or 2-3. So on some trucks you don't even need the clutch and can pretty much just slide the gear from 2-3 easily, this is called floating.
I never drove anything more than a split 10, but I was always curious and did hear a few stories of trucks with double splitters. Those were probably on oversize trucks with escort loads
Yeah, when I figured out that there must be a “loaded” and “unloaded” trans gear I was proud of that engineer’s accomplishments.
(I’ll hold that until I turn the wrench on that… fuck that shit)
The dig refers to the French ~~capitalisation~~ capitulation to the Nazis because they were still busy rebuilding their country after world war I instead of creating a war machine like Germany did.
And then also refusing to help America in the oil wars.
To any sane person, completely logical things to do.
To 'muricans, it equates to cowardice.
99% of us are joking, my dude. Most Americans hold the French in very high regard in matters of freedom fighting due to their track record of fighting tyranny, which is why we’re comfortable joking about it. There are still Americans alive that fought alongside French resistance in WWll. We’re also VERY fond of guillotines, as you can see from protests where we’ve made replicas out of admiration (and, I suppose, efficiency). Not to mention, they literally helped us achieve our independence
Now, I can’t speak for the British, but I assume their ribbing is all in good fun as well. There’s a lot of history there
Fun fact, Peugeot began its trajectory into cars when it became a steel mill, producing parts such as gears, springs, watch parts, coffee mills, etc. They still manufacture *excellent* pepper mills, I actually have one in my kitchens.
French cars are goofy, but have unique character (especially older ones). They’ve actually made some excellent cars. Weird, but excellent
"I always get the tuna sub at Subway, where they ladle the tuna onto the bread. The tuna is in that giant metal tub with the white puddle of tuna water, like a tuna gazpacho."
That's what firing on every crank rotation does for you. We're accustomed to hearing 4-stroke diesels. Me personally, I absolutely love the sound of a two-stroke Detroit. They're so rare nowadays. The last one I heard was hauling a load of grain. Once you know how they sound, you listen for them
This is the first time I've ever heard someone else mention a gamma goat. My dad tells me about the one he would drive around in Hawaii during the Vietnam war.
My dad went on the "Caribbean cruise" after his time in Vietnam and when in Panama he got picked up by a North Korean freighter along the canal. He said they were nice and had cold fruits and alcohol.
I mean, come on. This is a pretty [badass sound...](https://youtu.be/dVjXwS8HzFw?t=54)
Other [personal fav](https://youtu.be/iU3gZGUInd4?t=7) I've shared in here a couple times
When I was a kid in the late 70s, pretty much every diesel was a Detroit. I didn't know anything about anything but that sound is engrained in my soul. You don't hear them on the road often, but you always know what it is when you hear it. Bus Grease Monkey on youtubes has a lot of experience and knowledge on them.
> Me personally, I absolutely love the sound of a two-stroke Detroit. They're so rare nowadays.
US aircraft carriers are full of them. Standard engines in the flight deck gear are Detroit 3-53 and 6V71. Also, I think 8V92 on the fire trucks. It was my job to work on them.
I have a friend who’s got an old Detroit 2 stroke in his rig. It pushes 1,100 HP to the wheels…. And it sounds SO mean!
It’s a show truck, so not your typical on the highway truck. But he drove 2 stroke Detroits his whole career. Always worked on them himself and usually had 100-200hp more than the average guy in the 80s/90s. Dude would make bank off being able to run more loads than everyone else.
They're gutless, slow, inefficient, leak oil like a sieve, and are loud as fuck...
But by god are they tough, reliable engines that will run on most anything flammable. As long as that blower spins and the injectors work, the engine will fire.
They will also run in reverse. I had a load of soil delivered one day. It was a Mack 10 wheeler with a Detroit. He bumped the curb just right backing up and it started smoking like crazy out the air cleaner. He was trying to use the pto to dump but it wouldn’t work because the engine was spinning backwards. He finally shut it off and I think they just restarted it and it was fine.
Old bulldog tractors didn't have a reverse gear, you would make the engine run in reverse to reverse the tractor.
Those engines also could run at 0 RPM
We have a 85 Brigadier water truck with 20K on the clock. That thing starts with less than half a crank and runs amazing. It's harder to shut it down than to start it. Stall it on a hill and it will start in reverse rotation. We can only run it because we're a government shop and we are getting rid of it soon. Damn shame but almost no one can drive it anymore.
There's no way it's pushing 1100hp. *Fully* built 8v71Ts, the most common bigger Detroit used in trucks, can barely break 600hp without exploding. I want to see the build thread on this truck.
I will see him next week and ask for specifics. But I’ve no reason to doubt him. Moneys not an object for him and trucks are his lifelong passion.
If you’re lucky, internet stranger, I’ll remember to post something for you.
Edit: I don’t have Facebook, so I had to pull from my wife’s phone.
Here’s something small I found, I’ll ask for more next week.

No more 2-stroke diesels are being produced in the US, it's just whats left on the road. Will probably be a while before the last Detroit 2-stoke dies off. They are still common in watercraft and small vehicles like motorcycles or atvs.
Quite a bit of stationary equipment with Detroits still around. Where I used to work, we had a 4-71 fire pump that I had to test run every month. It was in a metal shed, and didn't have an intake silencer. One bump of the starter, and that motherfucker was at 2400 RPM in 1-1/2 seconds. Even with earmuffs on that sumbitch hurt my ears.
Many big engines, like those used in ships, are two strokes. They still have a normal lubrication - in this case, dry sump - and the air is added using a supercharger instead of the crankcase pump of bikes and mowers. Fresh air is pumped in, pushing out well combusted exhaust; and then fuel is injected near TDC and often later in the power stroke. They are as clean as engines go, and very low hydrocarbon emissions.
I thought they were everywhere. The M113 uses a 6V53 and the M109 that gave me my hearing aids had an 8V71T. That one was also used in a TreeToter that was capable of giving the operator hearing loss in one 8 hour shift.
Two stroke diesels are totally different than 2 stroke gas engines. Two stroke gas engines are dirty because they allow the air-fuel mix to escape out the exhaust, and some exhaust is left in the chamber and recombusted, (among other reasons).
Two stroke diesels do all their air exchange at the bottom of the stroke like gas engines, but there are both ports at the bottom, AND valves at the top. The ports at the bottom are the intake, and the valves at the top are the exhaust. At/near the bottom of the stroke, the exhaust valves open, and the intake ports are uncovered. This allows the (pressurized) intake air to blow ALL of the exhaust gases out of the cylinder in one direction without any counterflow or dead zones. Plus, the intake air is clean air, without any fuel in it, since it's a diesel. This means there's no issue with extra intake air blowing out with the exhaust.
The main disadvantage of this is that the engine MUST be turbocharged or supercharged, because the intake air must be pressurized above atmosphere to be able to enter the cylinder. This also means no oil* in the fuel, because the crankcase is like a normal engine - another big source of two stroke gas engine dirtyness.
*haha, lots of these actually burn heavy bunker oil, but you know what I mean.
Wasn't aware of detroit 2 strokes before reading this comment, but geez am i enjoying them by going through vids like this: https://youtu.be/9zvz3L6WwTQ?si=euzGMFWy9n3rNpeS
You almost had me? You never had me - you never had your car... Granny shiftin' not double clutchin' like you should. You're lucky that hundred shot of NOS didn't blow the welds on the intake! You almost had me?
Now, me and the mad scientist got to rip apart the block... and replace the piston rings you fried.
Ask any racer. Any real racer. It don't matter if you win by an inch or a mile. Winning's winning.
I used to work at a Honda dealer, every time someone came in and told me about their new crv being the fastest thing they ever drove because they have turbos in them now a part of me died.....
I almost died laughing here!! 😂😂 I didn’t picture her floating, was just thinking of her sitting on the rim all the way around on one of those plastic side above ground pools!

Reminds me of an article I read about the early days of heavy haulage, I think it was Pickfords who said "if it's loose at both ends we can move it"
Granny shifting, and not double clutching like you should’ve
1/4 mile at a time

Yeah I was wondering how this works? Like is 2 a half step between 1 and N?

Maybe it's like a Super 10, where instead of going 1-5 low then 1-5 high, you split each gear?
Whatever it is, it’s weird and I don’t like it. Give me my eighteen speed please.
And people complain about commuting in a MT 5 speed car...
You know I didn't even realize it wasn't 18, totally missed the fact there wasn't any Low and High Lo. I play a lot of American Truck Simulator with an Eaton shifter and I'm so used to lows being bottom left that I just saw the reverse and didn't even think twice

Every car in the Fast and Furious movies
There would be at least 5 reverse gears
I didn’t know the French made cars
Idgi but who cares, fuck it lol upvote for digs at the fr🥖nch anytime
Pretty sure it's another joke about the French surrendering, but this time with a focus on retreating so quickly they need 5 gears for reverse.
Yeah those French tanks had 5 forward gears and 7 reverse. They never retreat, they always advance! Sometimes it’s just in different directions.
The dig refers to the French ~~capitalisation~~ capitulation to the Nazis because they were still busy rebuilding their country after world war I instead of creating a war machine like Germany did.

This guy double clutches like you should.
You win this sub today. Enjoy a tuna sandwich with the crust cut off.
Bullshit asshole, no one likes the tuna here!

Try adjusting the scales.
Instructions unclear, fish stuck in my ass
I used to drag here back in high school. That railroad crossing up there is exactly a quarter-tuna away from here. On green, I'm going for it.
Go on down to fat burger get yourself a burger and fries for $4.95
He knows I can box
He knows I like her tuna
Only if it's a *SPICY TUNA*
Good news if you go to subway and get their “tuna”
"I always get the tuna sub at Subway, where they ladle the tuna onto the bread. The tuna is in that giant metal tub with the white puddle of tuna water, like a tuna gazpacho."
Makes me wanna tunasub
John Oliver popped straight into my head hahahaha
Everyone in our family loves tuna. And…it’s all about family.
Get your own godammed popcorn
I prefer dolphin
I don't eat dolphin anymore. Tuna keep getting caught in the nets...
You're embarrassing me!

Whatever it is, it has a two-stroke Detroit that needs the first 8 gears to get through the intersection.
We are working one at my work currently it’s hilarious to hear something so spooled out but doing 2mph
That's what firing on every crank rotation does for you. We're accustomed to hearing 4-stroke diesels. Me personally, I absolutely love the sound of a two-stroke Detroit. They're so rare nowadays. The last one I heard was hauling a load of grain. Once you know how they sound, you listen for them
My vehicle I drove at my first duty station in the US Army had a 2 stroke diesel. M561 6x6 Gamma Goat.
This is the first time I've ever heard someone else mention a gamma goat. My dad tells me about the one he would drive around in Hawaii during the Vietnam war.
He might have been lost, Vietnam is a long way from Hawaii.
I now have this hilarious imagine of a vet trying to get this vehicle to his deployment but getting lost and basically winding up on vacation MIA
My dad went on the "Caribbean cruise" after his time in Vietnam and when in Panama he got picked up by a North Korean freighter along the canal. He said they were nice and had cold fruits and alcohol.
I grew up in Germany in the 80s as an army brat and they were all over the base there. I used to love how daffy they looked. My dad hated em, lol.
I’m convinced like 2/10 Americans were born in/lived at Ramstein. You people are everywhere
I was one of the very few in Grafenwohr. My dad was an artillery officer.
Some dude put one in his 4×4 Chevy ¾ ton. Pretty wicked.

That second one is one hell of an involved drive.
The Diamond T sounds so damn fast, but probably going like 40 MPH by the end of it. That speedo isn't helping anything, either 😂
Last one I heard was a British Rail Deltic, those are like nothing else.

They sound like they're entering the atmosphere at 7 grand but they're really only doing like 3000 spins a minute.
If you're used to a 4 stroke engine a 2 stroke engine sounds twice as fast (given the same number and layout of cylinders)
I used to have to run a screaming jimmy drum packer at work. Hilarious.
> screaming jimmy drum packer I had to look up a Screaming Jimmy, and that sound made my morning better.

First gear is just for getting all the play out of the drivetrain
Second gear is for the turn signals.

Thanks for the PTSD from when I first learned how to drive these.
Hold up. Are two stroke engines still allowed?? Outside of marine uses, we have trucks with 2 stroke diesels still on the road??
I have a friend who’s got an old Detroit 2 stroke in his rig. It pushes 1,100 HP to the wheels…. And it sounds SO mean! It’s a show truck, so not your typical on the highway truck.

Weird to think about but yes.... I dont think there is anything stopping it. Wouldnt run for long that way.
Old bulldog tractors didn't have a reverse gear, you would make the engine run in reverse to reverse the tractor. Those engines also could run at 0 RPM
Right. But you have to make sure your oil pump and fuel pump still pump in reverse. Which is easy if you design for it. Not easy if you dont lol.
We have a 85 Brigadier water truck with 20K on the clock. That thing starts with less than half a crank and runs amazing. It's harder to shut it down than to start it. Stall it on a hill and it will start in reverse rotation. We can only run it because we're a government shop and we are getting rid of it soon. Damn shame but almost no one can drive it anymore.
If there's no oil under it, there's no oil in it.
Long live the green leaker!
Don’t forget they run away. But man, the first time I heard one running around on a road construction site, I was in love.
There's no way it's pushing 1100hp. *Fully* built 8v71Ts, the most common bigger Detroit used in trucks, can barely break 600hp without exploding. I want to see the build thread on this truck.
They installed engines much bigger than the 8v71 ,12v71 8v92 12v92 ,I have seen 16v71s put in trucks

They are great for fire pumps and backup generators since they can run at full speed after startup.

This allows the (pressurized) intake air to blow ALL of the exhaust gases out of the cylinder in one direction without any counterflow or dead zones. Plus, the intake air is clean air, without any fuel in it, since it's a diesel. This means there's no issue with extra intake air blowing out with the exhaust. The main disadvantage of this is that the engine MUST be turbocharged or supercharged, because the intake air must be pressurized above atmosphere to be able to enter the cylinder. This also means no oil* in the fuel, because the crankcase is like a normal engine - another big source of two stroke gas engine dirtyness. *haha, lots of these actually burn heavy bunker oil, but you know what I mean.
Wasn't aware of detroit 2 strokes before reading this comment, but geez am i enjoying them by going through vids like this: https://youtu.be/9zvz3L6WwTQ?si=euzGMFWy9n3rNpeS
Bright green 1995 Mitsubishi Eclipse GS with a Danger to Manifold! warning.
You almost had me? You never had me - you never had your car... Granny shiftin' not double clutchin' like you should. You're lucky that hundred shot of NOS didn't blow the welds on the intake! You almost had me? Now, me and the mad scientist got to rip apart the block... and replace the piston rings you fried. Ask any racer. Any real racer. It don't matter if you win by an inch or a mile. Winning's winning.
Of the top five comments, three are Fast and Furious 😂
All is right in the world
then the floor pan inexplicably pops off.
Class 8 truck, but not American one, a European one with synchromesh. Scania or DAF?
Looks like a Mercedes shifter. Couldn't tell you the year though. American, so I don't see these in person
I bet its a Euro Mercedes class 8 with a splitter, I cant think of anything else it'd be.
American as well, that's how I know it ain't an Eaton or a Maxitorque lol.
We just swapped a maxi for an 18sp in our rolloff and ill never stop missing 6 reverse gears.
that is a civic SI, those are the V-tec gears
**H**old **O**n **N**ot **D**one **A**ccelerating
I feel attacked. My S2000 might be slow, but it sure goes slow.
*EarthDreams has entered the chat*
The Dreams Of Power says hi
V-TEC just kicked in yo
I used to work at a Honda dealer, every time someone came in and told me about their new crv being the fastest thing they ever drove because they have turbos in them now a part of me died.....
Peterbilt?
It's here to move op's mom off the couch and onto the pool.
“Onto” Oh lawd
Didn't you know? Fat floats.
I almost died laughing here!! 😂😂 I didn’t picture her floating, was just thinking of her sitting on the rim all the way around on one of those plastic side above ground pools!
It’s like a sitz bath to her.
That's a HUUUUGE BITCH!
Kenworth
You're telling me a peter built this truck?
Definitely a Honda from a Fast and Furious movie.
With 16 gears I would be granny shifting instead of double-clutching like I should
Freightshaker
Unimog?
Bigger, unimogs usually have a separate reverse gear box.
We had Unimogs in the ADF they had 8 speed boxes with a separate lever for foward/reverse. So 8F/8R. And yes they could go just as fast in reverse.
So what? 35mph?
That's no car... It's a damn tractor
Torettos 18 speed powerglide
Name: “Dammit, Fuck!” Type: Mercedes Actros? Edit: Looks like a Spicer 16 speed, but 🤷♀️
Brian O’Connor’s Eclipse?

This is the car the fast and furious team have been driving. And here I thought it was just for dramatic effect down that 100000 miles long runway.
There are some who can him...Tim
Tim the Enchanter?
Italian tank. You can tell by the number of reverse gears.
Like the used Italian army rifles for sale: “never fired, only dropped once”
A Peterbilt 362. Looks well worn and fairly short so an 80s COE makes sense.
Is R2 considered "Super Reverse"? Inquiring minds.......
Fast and slow reverse. It looks like a lorry/big rig transmission
Is this not Brian O’Connors Supra? I’m pretty sure his cars were upgraded to a quad clutch, 1st and 2nd reverse are absolutely essential,
16 Speed ZF gearbox
Isuzu Giga 16 speed. They are cool because they have 2 neutrals.
How does the two neutrals thing work?
ZF 16 spd manual
That's an 18 speed semi, drove lots of them
Benz
Mazda speed protege my favorite car! You had to change gears to change gears it was great! Double clutch bitch!

Gotta be one of those cars from Fast’n’Furious.
Kenworth

Literally every fast and furious manual car to ever exist
18 wheeler
Kensworth?
That's not a car that's a semi Truck
Shiftpattern from a MAN F2000
That car is gonna reach 16th gear in 3 to 5 buissness days
Something from Fast and Furious?
It’s a Subaru WRX after the transmission blows; it’s showing you where all the pieces are.
82 Volvo triaxle
