How an Automated Manual Transmission Works

[@supersabrosinho]

I'm a design engineer for a 2nd tier supplier. For those of you wondering, this concept was built upon a 40 yr old design that has been developed over the years through an iterative process. Designers usually don't come up with this from scratch, why reinvent the wheel when we can perfect it! With that being said: anybody with the right mindset and attitude can be an engineer. Anybody can do this!

[@speedkar99]

They sure can but it's not very popular amongst other manufacturers. The planetary system won out.

[@Steel_the_Free]

"...anybody with the right mindset and attitude can be an engineer. Anybody can do this!" This comment deserves a KZbin "All Thumbs Alert" (ATA). ATA-boy Lo-pee!

[@accordinglyryan]

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

[@applepoop10]

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!

[@accordinglyryan]

@@applepoop10 In the grand scheme of things no it isn't lol. It's like $40-50 every 20-30,000 miles if you DIY. Who cares

[@nasedo3129]

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.

[@supersabrosinho]

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]

It sure is complex. And to think of the mass manufacturing scale...every car on the road has something just as complex

[@mrkzj2]

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.

[@TuneStunnaMusic]

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]

Yep I've read about all that but it wasn't applicable to this transmission which was from an 05 Accord hybrid

[@mrkzj2]

@@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.

[@mrkzj2]

@@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.

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.

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)?

[@speedkar99]

I'd definitely change the fluid frequently. It's a Honda Automatic that's failure prone.

[@pliedtka]

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.

[@MrManuel1329]

@@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.
