@@francoisgirard2306 holy shit…you're right! In 2017, in the 10 speed… Soichiro was against the idea of planetary gears, hence the development of the Hondamatic. I'm disappointed.
I always knew Honda ATs were unique and basically manuals, but it's cool to actually see what's inside of one. These things definitely like frequent fluid changes, I notice a positive difference in shift quality every time I service mine. And I do it every 15-20,000 miles lol
They suck, because they require very specific automatic transmission fluid from Honda to function properly and prolong long life. Honda DW-1 fluid is expensive!
Mechanic here. It's worth noting that there was often a second, external fluid filter that was easily replaced. V6 transmission failures are largely isolated to models before around 2005, and were primarily the result of poor cooler circuit flow in the valve body. That caused the converter clutch to sometimes drag, building up excessive heat, and eventually burning second gear.. other gears followed. Early 5-speed models had additional cooling jets to help reduce the heat, but the aftermarket eventually discovered ways to modify the cooler circuit and virtually end premature trans failures.
I have a BXMA with a flaring 4th gear, and i probably should get this external filter installed before the trans burns itself up. Ive been reading about it.
@@speedkar99 Nah the main difference there is the second fluid pump, but they still fail like all the others. Rebuilt a number of these, a few of which were from Accord hybrids, and of course dealt with a million at the dealership. A good valve body cleaning including polishing the bores, pressure testing the valves, modifying cooler flow, etc. works wonders. Very rarely see internal filter restrictions - those usually happen with burned clutches from driving with slips and flares too long.
@@TuneStunnaMusic I'd say it's probably too late to save with just a filter. You may be looking at excessive clutch wear, a damaged bore, etc. If it flares only during the 3-4 upshift but doesn't slip once engaged in 4th, you CAN baby it for quite a while. I know customers that have limped flaring 2nd gears for 20,000-50,000 miles.

Staggering complexity. Automatic transmissions are truly a wonder of the world. I try to imagine what it would be like to design the case or the valve body, then make a drawing that the foundry can use to build the mold to cast those parts and the machinists can use to machine the parts to the correct tolerances. Those guys are living in an entirely different world from me. Whatever they are being paid, it isn't enough.
It's an iterative process. We build upon existing designs, and prototypes. These transmissions have been around for a long time, we don't need to reinvent the wheel. Anybody can do this with the right training and passion!
@@speedkar99 Thanks for your enlightening video. I am wondering if it is as crappy as other Dual Clutch transmissions like DSG, Ford Fiesta, many Hyundai and KIA DCT, etc. It has torque converter, so it is not actually a manual transmission with dual-clutch style. JYI, In EU Toyota at certain period also have DCT type transmission on their Auris1 and Yaris, the clutch wears out all the time and cost close to $1000 to replace it. Not as expensive as the robots in DSG from VW.
I rebuilt one of these dual shaft 4 speed Honda AT's out of a Civic with a D16. Great unit to start on. I'd never done anything that complicated beofre, and to my great surprise, the rebuild went perfectly and the transmission functioned like new! I've been fascinated with them ever since...love your videos man!

A lot of the CB7 (1990-1993) Accords have issues with the transmission control unit failing, if you've got one of these that won't shift look under the passenger side carpet - there are 2 control units (early 90s tech yay) pull out the one closer to the passenger door and open it up and look for burnt resistors in one corner. Get a "Denshigiken" TCU and chuck the OkiData TCU and most often that gets them going again.

Honda never used planetary gears in their in-house automatics till the 10 speed in the 2018 accord. Before that it was always automated manuals because they didnt want to pay patent licenses. Smart.
1:25 - really don't love the way they made it impossible to get at that filter without splitting the transmission case. 🤓 The externally mounted solenoids are nice from a service perspective though.
I'm confused. At first I thought this was a dual-clutch transmission (DCT). But a DCT doesn't require a torque converter. Also a DCT uses two concentric shafts, one for the even numbered gears and one for the odd numbered gears. What kind of frankenstein monster is this?
One thing for certain that this is no GM 4L60-E with burned 3-4 clutch pack and a broken rear driveshell with no reverse. It's gonna a real pain to change a cheap filter on that Honda gearbox.
You hardly ever replace the filter on the newer tranny's. And, actually in the ones we took the pan down there wasn't much crap in the filter. Usually it's something electronic, the valves, etc, that fails.
@@speedkar99 I disagree. it is indeed an automatic manual. just a different style. I? think the title would work best if you specified how hondas automatic manual works. rather than just as a whole.
The automatic transmissions used in the Saturn S-Series cars (91-02) also used this kind "Automated Manual" layout. (although calling it an automated manual is a bit of a misnomer)
Kudos for the engineering, but the more I learn about trans and overall mechanics, one thing is a fact, if you want everything reliabely out of an engine, manuals are kings of efficiency, at most, dct's are the only automatics close to a manual, but damn, they break a lot and are utter expensive to fix (usually).
The Toyota hybrid transmissions are mechanically even simpler than a manual transmission. I would dare to say that they can be more reliable and efficient than a manual transmission. The electronics needed for it have been perfected for over 20 years and hardly ever fail.
@@speedkar99 correct. But in idle stop, the aux pump will run to keep pressure in the body as you stated. Then the torque converter is the main pump. They work kinda backwards from a traditional planetary. But lots of good information for those curious.
I appreciate if hou could mention torque converter in the heading, so that people are not familiar with transmission types wont get the feeling like all automated transmissions are torque converter based.
This shows very clear why I prefer a manual 5-speed gearbox. I always buy end-of-life cars for a few hundred euros. This gearbox is so overcomplicated. All this to automate something that is in fact a no-brainer. I am never conscious of shifting. It is done "automatically"!
@@speedkar99 What I mean is this: Compared to a manual it contains so many parts that can go wrong. When I test drive a manual car I shift it through the gears testing the synchronization, listen for any nasty noises, and violently pump the accelerator in any gear to make sure it doesn't jump out. When the gearbox is not leaking it is fine for me. This semi-automatic gearbox is more difficult to test. You can not really access any wear of all the clutches. My advice for buying high mileage older cars is to stick to a manual. In the Netherlands where I live the majority of smaller and medium-size cars are manual anyway. But nice video! So much clearer when you see the real thing!
With the filter being almost impossible to change, is this a true "lifetime fluid" transmission? Or does it still recommend fluid change interval (with a lifetime filter)?
Yes, there's lifetime fluid - you discard it together with the transmission. My father also asked the same question it cost him a few instead of $150 for fluid change. So since some car manufacturers say that the fluid is life time, the tranny manufacturer will tell you do replace the fluid at their recommended intervals, say 50k for Honda, 80k for Aisin and ZF (German maker but used also in new Honda), and so on.
Honda recommends every 30k religiously. The number 3 maintenance minder that's pops up when it's time for a oil change in every Honda ever means it's time to change the transmission fluid also. ONLY USE HONDA FLUID!!
@@speedkar99 From what I can tell the RL just uses a FWD gearbox similar to that which you dissected with a transfer case attached to send the drive to the rear mounted diff/acceleration device. Now opening up the RL SH-AWD unit if you could find a dead one would be interesting...to this owner at least. Cheers
my car has this gearbox (AMT). What happens when you're stopped at a traffic light and hit the brakes? Is the gearbox under pressure? Should I put it in neutral (N)?
What model code is this? Is this in any years of the RDX/MDX? The way you check the fluid on Honda's is very specific, and I wonder if it has something to with it.

Transmission oil change on this AMT , is done on how many km? I have one in my Peugeot 3008, and manuel says don’t change the oil if you dont have problem. Wtf? I’m so confused!!!
I wouldn’t consider that an AMT. AMTs are literally “automated manual transmissions”, which means there’s a clutch instead of torque converter (and no, the lockup clutch DOES NOT counts). It’s just an automatic but with conventional gears, instead of planetary ones.
@@speedkar99 I researched the whole history cause I was bored one day. To make a long story short, I think it is because they started with small engines and smaller fwd cars. The design starts to fail in higher power and heavier fwd cars. Just my guess. Just not sure how the design is more efficient than the older slush boxes like the ones GM invented.
@@speedkar99 the 4 shaft was also used in the Acura tl from 07-11 and the rl. Pretty much every Honda Switched this this by 2008 and thank goodness they did.
Everyone who uses the word "car" should be asked to calculate the peak force between engaging gear teeth of two meshing gears "X - Y" during an acceleration e.g. of zero to 60 mph (100 kmh). Then pay homage to those geniuses who"ve taken the worry out of your hurry.
Any REAL Automated MANUAL GEARBOX out there with a torque converter? Manual transmissions are rugged, but robotized manual transmissions seem to be poor in bumper to bumper traffic, generally burning the friction clutches.

So since some car manufacturers say that the fluid is life time, the tranny manufacturer will tell you do replace the fluid at their recommended intervals, say 50k for Honda, 80k for Aisin and ZF (German maker but used also in new Honda), and so on.
Honda recommends every 30k religiously. The number 3 maintenance minder that's pops up when it's time for a oil change in every Honda ever means it's time to change the transmission fluid also. ONLY USE HONDA FLUID!!

Check your transmission manufacturer website, if you still can't find it change it every 20.000 kilometers, better safe than sorry 🤣🤣
Just do it once a year
Was expecting a honda from 98-02
I'd like to source a failed one and examine the causes of typical failure. Those were really bad
Acura Legend, Vigor, Odyssey- very famous for that.
I have a 2008 Honda Civic automatic Honda is telling me I need a transmission flush and it hasn’t been done in 2 years. Now is it safe to do a flush ,
Drain and fill
Nice
I wouldn’t consider that an AMT. AMTs are literally “automated manual transmissions”, which means there’s a clutch instead of torque converter (and no, the lockup clutch DOES NOT counts). It’s just an automatic but with conventional gears, instead of planetary ones.
Alright.
Does automated manual transmission and Robotic transmission are the same ?
I guess.
Wow, pretty complex!
I think it's simple....compared to a conventional automatic
Like power shift transmissions
What's that
Heavy equipment transmission
It's hard to flow along when these cogs aren't rotating and engaging with eachother.
Bagus sekali pak
Iya
Why do they still use hydraulic circuits instead of electronic controller as the brain of the transmission?
Because the clutches are hydraulic.
If the clutches were electromagnets then it would be a circuit board
So did the DCTs replace the AMTs
Kinda
Opticruise.
Why did Honda do it this way? What are the advantages? It still needs a torque converter.
That's the way they've done it for years. Unfortunately reliability suffered
@@speedkar99 I researched the whole history cause I was bored one day. To make a long story short, I think it is because they started with small engines and smaller fwd cars. The design starts to fail in higher power and heavier fwd cars. Just my guess. Just not sure how the design is more efficient than the older slush boxes like the ones GM invented.
Are these in the 05 V6 non-hybrid as well? I know I have a 5 speed auto but I don’t know if it’s any different.
Similar concept but I think that has 3 shafts instead of 4. They made the hybrid more compact because they had to include a motor.
So there's a clutch for every gear?
Beats shift forks....
Yep
Does my 2014 Crosstour have this type of transmission?
Most likely.
@@speedkar99 it's mated to the K24, does the j35 use the same trans?
@@MISTER__OWL yes
Is the 5-speed manual transmission in my 2011 Civic reliable?
Yes
Sure
This is the revised 4 shaft 5 speed auto. The older 3 shaft ones were horrible.
This is a 4 shaft because it's from a hybrid and they had to make the transmission slimmer
@@speedkar99 the 4 shaft was also used in the Acura tl from 07-11 and the rl. Pretty much every Honda Switched this this by 2008 and thank goodness they did.
HONDAMATIC
Yes
I hope not, those had issues and were expensive. And that was a motorcycle.
Thank you for teaching! But this transmission is seems designed to fail. And all new automatic transmission to.
Manual ftw
please need some honda i dcd transmission info
Dcd?
I thought it was just a manual with actuators on the forks and the clutch
Forks would be extra when they can use a wet clutch
hey man you are using too much stuff from your brother 😂😂
That's his problem
I like how he uses his family's clothes in the process of explaining his videos.
Now I understand why I will never fully understand lol
Lol
its so complicated with many parts ready to fail
Everyone who uses the word "car" should be asked to calculate the peak force between engaging gear teeth of two meshing gears "X - Y" during an acceleration e.g. of zero to 60 mph (100 kmh). Then pay homage to those geniuses who"ve taken the worry out of your hurry.
6kN
@@speedkar99 Thanks for the "Newtons". 1,350 pound-force.
Sir this is a wendy's
this is why the internet is beutiful
It sure is
Any REAL Automated MANUAL GEARBOX out there with a torque converter? Manual transmissions are rugged, but robotized manual transmissions seem to be poor in bumper to bumper traffic, generally burning the friction clutches.
I don't know why but ur channel keep getting unsubscribe automatically. I have to keep subscribe it again & i will keep doing it its a nice channel. You are taking a lot of efforts. One question is Koenigsegg Compounding LSF transmission as complex as this or little bit simple?
