My Mini Cooper JCW GP has an Aisin 8 speed. From what I can tell so far it feels like a very stout transmission, quick strong upshifts and downshifts and it puts the power down very well. If I leave it in sport auto mode, I can be cruising in 8th gear on the highway and if I mash the throttle it downshifts to 3rd with quickness and takes off like a rocket. Or I can manually shift down with the paddles or gear selector for more involvement. After having only manual cars for the past 6 years (until the Mini) I thought automatic transmissions were bad... but I was so wrong. These transmissions are incredible.
@gravityhammer25 - Interested in your comment. We have recently bought a UK 2023 Mini JCW (228bhp) and are very pleased with the transmission. Having been used to VW brand DSGs (with diesels) for many years in various vehicles, the Aisin has low-speed smoothness that DSG just doesn’t, and coz the Aisin has a torque converter I have no worries about slipping clutches wear or heating up in slow traffic etc. Low-speed manoeuvring is now a positive dream rather than awkward. The DSG when cold is nowhere near as good. Having said that I still like the DSG, and one remains as my “daily”.
@@adrianlw2750 I carry the motion that Aisin 8 is sublime in both low speed cruise in traffic and when manoeuvring back and forth. The only advantage dual clutch types have over this is when entering or exiting the cruise mode the obvious mass of the torque converter initial spin compared to just a clutch engage with the dual clutch types. I love that the Aisin can kick down 4 gears at a time when wanted as well. Great part overall.
Very informative video. Very good explanation. Mr. John Kelly , thank you for sharing your knowledge and mastery of this topic with the world. Best video on RUclips i have found on this topic. Respect.
Excellent video as usual John and of special interest to me as I have it fitted to my new Volvo XC90. In that application there are two special features. First is the Eco drive mode which has an over-run declutch feature so that it completely coasts with no engine braking on a trailing throttle. This may be a mechanical feature such as a one way clutch inside the transmission. The second is the Off-Road drive mode which holds first gear to high revs and includes downhill brake assist, which is accomplished by software and the ABS system as far as I can make out. It also has a transfer box or at least a crown wheel and pinion for transfer of drive to the rear axle on most XC90 variants and that is all variants available here in the UK. Of course the same Aisin transmission is being used in V and S90 models and 60 series also which are mostly sold as front wheel drive. My example is mated to the excellent 235hp 480Nm [approximately] twin turbo two litre diesel engine. The fuel economy and performance both exceed my expectations for a big 2.25 ton car. Yesterday I covered 205 miles, much of it at between 80 and 90 mph, with about 10 miles of city driving and 60 of twisty country roads and achieved 38mpg Imperial or 32 mpg US. Average speed of just over 50mph.
Of all the components of any Vehicle , I find these automatic transmission the most complex ...with a lot of mechanical and electric synchronization . It’s enough to give you 8 headaches . But this is an awesome video.
Thank you for this! It seems like this transmission is a nightmare when it goes wrong, especially with all the clutches and that band. They leave back a lot of residue over the time which cause problems.
I rented a 2018 Camry with this 8 speed transmission and I was suprised the car had almost 100k miles already and everything was holding up well transmission/engine/interior wise. Didnt notice anything out of the ordinary.
Aisin transmissions hold up really well in my experience. My old Suzuki had one and it was sold something like four times and the guy that has it now is still driving it around on the same transmission. That's over 22 years later. Keeping the fluid changed regularly will do a lot to keep them running well.
Great video. Good explanation. I got here, searching what type transmission will our 8 Speed Auto Insignia have... And I find the whole tear down... Awesome! :) Thank you!
Fascinating. I owned a 2007 Lexus LS 460, and it was equipped with the same Aisin 8-speed transmission. The later IS-F probably was the same but a heavier service variant. As with most Lexus models, they are rear-wheel driven. Only the ES has the 6-spd FWD. I can't say for sure who produces that unit, but since Asin Seiki is part of the Toyota family, it's a safe bet they make it as well.
You are correct, the 2007 model year was the first year for the Aisin AW 8-speed AA80E in the Lexus LS 460. I was wrong. The RX series is also front wheel drive or all wheel drive. Thanks for your feedback!

Hello from Kerala, India. I own a front wheel drive 2014 XC60 2.0L Diesel D4 with the same Aisin 8 Speed Gearbox mentioned here. The car has run 30,000 kms. Recently a warning message showing "Coolant Low - Switch off Engine". Upon checking , I saw the coolant reservoir tank was empty and it had a brown oily kind of residue. I sent the vehicle by Flat bed to the Volvo dealer in Kochi. A couple of days later after checking, the dealer informed that the Coolant had leaked into the Gearbox via a failed cooler resulting in shift shock. They said Volvo recommends the Gearbox to be replaced! To replace a Gearbox in a car that's run only 30,000 kms sounds absurd. This is the same 8 Speed Aisin Gearbox that comes in the current Volvo XC60,XC90 and XC40.
I have similar problem in BMW X1 with same 8 speed Aisin gearbox, on 70k km, 6 years old, once it alarmed that Transmission is too hot. What did you do after, you changed gearbox or repaired problem? thanks
@@goodkutty Thanks for answer. Today Bmw service recomended to change Aisin gearbox but on my expense only. On many other forums I found lot of Bmw X1 owners with damaged automatic gearboxes at very low mileage. So I think it is not isolated case.
Have this transmission in a BMW 2er Gran Tourer LCI. Very nice driving feel with it. My concern: the manufacturer says it doesn't need any oil change, but users in real world say you should change the gearbox oil and filter at about 60.000 miles. Others say that after you do the oil change the problems with this gearbox begin. So what's your input in this matter, please? PS: one of my friend noticed at around 65k miles that the gears were lagging and having difficulties changing gears. After the oil change at a local garage, the gearbox was back to normal in operation.
HI. Thanks for the thorough demo of this transaxle. After rewinding the video a couple of times i still get the same doubt, can you please clarify it to me: How come the drum that is stoped by the band has got 3 clutches under it (aswell as the 3 yellow corresponding labels) and only 2 pistons?

@@WeberAuto Many PSA models (Peugeot, Citroen, probably any new Vauxhall/Opel models in the future) have, or will soon get, this transaxle. PSA look like building them under licence in Europe to shorten supply lines. I came here to see what was going on under the bonnet of my 2019 Citroen Berlingo. So far, it seems lovely to drive but not as fuel efficient in town as the old robotised manual 6-speed.
As i understand it still has 4 sun gears therefore 4 planetary assy. 2 of the are Simmons and two separate. Only thing is there are arranged in two pairs by merging two planetary carriers into one piece
Hi, no, this transaxle only has three sun gears. One in the simple gear set in the front, and two in the Ravigneaux gear set in the rear. There is no Simpson gear set in this transaxle. Thanks for your feedback!
Off topic John I apologise.....do you have any plans to make a video about the L110 hybrid transmission from Lexus. I ask because as you know it features a ravigneaux set and it'd be nice to see you do it. I'll now watch this video! Thanks as ever.
Hello, thanks for filming such detailed video. I had a 2006 volvo S80 with TF80 -SC gearbox. In user manual it say JWS 3309 (Type 4) oil should be used for fluid change. But in later models it says JWS 3324 (AW-1) should be used. While other car manufacturers using TF-80 series claimed AW-1 should be used regardless of model year, should I use AW-1 for fluid instead? Thanks Best Regards from Hong Kong.
I watch a lot of your videos. Very informative though sometimes too technical for me. I always prided myself in doing much of my own car maintenance but as I get older these transmission are getting more complicated not to mention the specialized tools that are needed. Are these 8 speed AISAN transmissions that go in the Toyota reliable. I know they're the next generation of the 6 speeds which have had a good track record.....wondering if the 8 speeds are just as good. Also what are your thought on transmission fluid servicing since many manufactures say life time fluid. Some say every 30,000-50,000 miles....others say follow the owners manual. To me it's like taking a bath in dirty water.
Thank you. I have a complete series of videos on transmission fluids. I also created several Wikipedia pages on transmission fluids. Always follow the manufacturer's maintenance plan. Most drivers meet the severe service requirements of every 60,000 miles for Toyota ATF.
@@WeberAuto I just watched your video about the Toyota ATF history. This was most helpful!!!! And thank you. I noticed Aisin makes WS fluid and says it's synthetic. I also found MITASU makes WS WTF and it's Synthetic but Toyota WS fluid makes no mention it's synthetic and many people say it's not a good fluid. Never know who to believe...Amsoil of course say they make the best fluid...so confusing........do you have any videos on transmission coolers and their effectiveness? Best Dennis
I rented a 2017 2wd Ram 3.6 v6 with the 8 speed. Before I drove the truck. I thought 8 gears was to many. Now I wish my 2016 F165 (F150 with 2.7 twin turbo v6) had one. It also shift a lot better than my truck.
Thanks for well explaining the function of the gearbox, but the way I want to know how reliable is the puretech 1.6 engine and it using the wet timing belt or chain?
I have a question about this type transmission . My BMW F46 220D LCI is matted with 8 speed AISIN GA8G45AW and I cant find info about interval service ( transmission oil change ) . The car miliage is about 78k and everything is ok but I am dont believe about the life time fluid statement. So what your opinion is about transmission interval service ?
I have problem with same gearbox on 70k km, 6 years old, Transmission too hot alarm triggered once. BMW dealer never changed oil in transmission and they say that changing oil will not solve problem. I am still waiting from them what to do next with gearbox. Any advice is welcome
@@versys23 After detailed research my advice is to get over 10 liters transmission and make two-three standart changes. Oil temperature must be between 35-45 C and don't sent info to transmission comp " oil changed ".
I got information from authorised Bmw service where I bought the car that Aisin gearbox needs to be changed on my own expense around 7500 euro. Dissapointed with Bmw Tomic Croatia and their behavior to client. I will try to seek my rights since I consider that this gearbox is fraud if it needs to be changed on 70 000 km
Amen, amen and AMEN! For they try and try with all kind of technical scenarios-DCT's and CVT's etc; but NOT one of them can equal (not to mention "better") a standard planetary transmission when it comes to automatic transmissions IMHO. Yes the others are cheaper to build (especially CVT) but a nightmare to fix them. For what it's worth.
Interesting video. Slightly off topic question. Toyota usually uses Aisin transmissions for their cars. Toyota has always had a good reputation for reliable automatics. How come the European cars that use the AW55 transmission are considered to have weak transmissions? The AW55 does not appear to be used by Toyota but it's still made by Aisin.
Toyota typically renames the Aisin transmissions they use to a Toyota designation. I do not know if Toyota used the AW55 because I don't know what they would have called it. Aisin builds great transmissions, but they have not been without some failures. Additionally, vehicle manufacturers pick the Aisin transmission they want to use. Maybe they picked a model that was not the best pick for their vehicle for some reason (typically $$), i don't really know. Best wishes.
WeberAuto The AW55 had features such as the clutch disengagement at rest in D and the super smooth shifts (when working properly) that were matched to small Luxury cars. I understand firmer shifts at better for long life? Thanks for all your videos
@@WeberAuto I believe Volvo used to have problems with AW55s because of "neutral-drop" and other software behavior which put too much stress on the internal components. It was a case of "a good deed never goes unpunished". I believe they were trying to save fuel but overcomplicated the functional behavior of the unit ... which might be a clue as to why other brands' Aisin boxes have lesser reputations.
Nice to see this video, just wondering if it is possible to retrofit this gearbox to 1.9JTD 16V (1910cc) engine? I am not sure if it is a M32 or C635 manual gearbox now on my car, but would really like to get this gearbox on it. What signals does it need from ECU or any other component if there is any data for something like this?
I've got a camry with this transmission, i have to say i'm not really a fan. Maybe it's because i have a 4cyl, or probably just the programming, but it will downshift and the slightest hint of throttle input and it cannot pull in any gear. This causes countless shifts for even a short drive.
I would rather have easy downshifts than very late and reluctant (and usually jerky) ones in my 2022 Mazda 3. The car is tuned to try and adjust the torque converter as long as possible before downshifting, but it usually ends up lugging the engine and ruining throttle response.
Small wonder CVT transmissions are so numerous. About 8% of the number of parts to these designed correctly. Cheap is the go-to route for new vehicles.
John, you mentioned an extra solenoid for auto-stop engines. What does that solenoid do? Is it something to do with the restart of the engine/torque converter clutch?
Good afternoon. I'm terribly sorry. I understand correctly - the GA8F22AW gearbox and the UA 80E gearbox are identical gearboxes with different hydraulic units?
I've got a some questions, but as always your videos are very good. You touched on 3 versions to handle different torque levels, could you eleberate on the 3 versions and how much torque they are good for? I own a 1995 Mitsubishi 3000GT, it's FWD. Latter I would like to modify it with turbos and all that. Right now the car is fun to drive stock as it is, but gas miliage sucks even at the 222 HP stock level. Transaxle is a 4 speed OEM. Do you think I could get one of those 8 speeds to fit in my car? If so, which one is best for higher torque levels that would fit in there? Also, do you know of any 7 or 8 speed AWD transaxles that may be made to work in my car? Thanks for your time.
Waiting for my Volvo V60 to be delivered, I had to watch this. Great video, thanks. ... But now I cannot get out of my head trying to figure out how many reverse gears it could deliver... In theory of course?
Great video John, but from around 25:30 to 26:00 you're describing the front gear set with the sun held, carrier input, and ring output. How is this not producing minimum forward overdrive from this gear set?
Thank you! Great observation! A single pinion planetary gear set would have an overdrive condition with the sun held and the carrier as the input, but this is a double planetary carrier gear set. It reverses the direction of the ring and slows it down. The formula is Wa=1/((Na/Ns)-1)/(Na/Ns) where Wa is the speed of the annulus gear (ring) and Na and Ns are the number of teeth on the sun and annulus gears. Na = 78, Ns = 38. I hope that helps. Have a good day!
I have a 2016 Chevy Malibu 2.0 with a 8 spd transmission. I see Raybestos makes stronger clutches. The diff is open but these trans are used by other manufacturers like bmw etc. wonder if I can take a LSD diff from a bmw and put into my aisin GM 8 spd transmission
Very good video, thank you for that. I've still got a question, in my 2021 Citroën C4 is an Aisin 8 Speed Transmission mounted. When I am in "D" Mode, the car is not crawling very well at very slow speed with the brakes applied. But, if I switch to "M" Mode, it's very easy to let it crawl with brakes applied. What is the difference between "D" in first gear and "M" with first gear?
Same “problem” with 2021 Peugeot 5008. I had the eat6 in my older 5008 (2018) that was perfect. This gearbox is really not suited frictie car. Also very strange noises in 5th and 7th gear at light load. The crawling in stop/start traffic drives me nuts… it looks to be the torque converter I guess..
I like watching your channel. It’s really professional and useful. I was just wondering if the Aisin transmission is torque converter type or not ?. Thanks.
What is the most common problem with these boxes? I've been reading there was a lot of issues on Bmw X1 and X2 models, mostly replacing the whole gearbox.
Any particular reason why bands have fallen out of favor? I read an SAE paper by Aisin claiming their modern double-wrap bands have lower drag losses than an equivalent clutch pack and have just as good controllability/response
Hi great info on this video. I have a 2016 volvo xc90 with this transmission. There is slippage when transmission is cold my Volvo main dealer says there is nothing wrong. Should this transmission slip? Many thanks.
since no one replied you, yes it is normal on those tranies, they do that until the gearbox hits an certain temperatur, dont think you should floor it before the engine and tranny has been warmed up
I have a question let’s assume a vehicle drives at 60 mph and the ECU changes gears from 4 to 5 during these milliseconds when disengaging and engaging a clutch what happens in the output shaft and rpm
I have a 2016 Cadillac cts vsport with the aisin 8 speed and when my car gets to operating temperature and in 7th and 8th gear mostly my car will start hesitating. What causes this? I’ve taken it to the dealer several times and they can’t get it to do it with them. Oil and filter been changed 3times by dealer
Sir, I like this video n the 8 speed transmission. But the braking bands had me worried that might break the fluid, produce metal particles n shorten gear life when the bands are taking a greater proportion of the braking load.
Love your videos.....very informative.....I am wondering in your opinion why are manufacturers making it so difficult for owners to service their transmissions? If the 8 sp transmission is used in multiple models why do some come with a dip stick and some not?
Thank you. The answer is simple, today's fluids are better quality and will last a very long time if nobody bothers it or adds the wrong fluid to the transmission. See the Toyota ATF history video I made ruclips.net/video/t73jM6mT8sU/видео.html&lc=UgzXiCE-Slhijah7ykJ4AaABAg and the wikipedia page I created on Toyota ATF at en.wikipedia.org/wiki/Toyota_Automatic_Transmission_Fluid#Toyota_%22Lifetime%22_ATF Best wishes!
Hello, I intend to buy opel insignia gsi 4x4 209 PS 2019, with 123.000km. In this insignia is aisin AF 50 - 8 3 generation. Can you tell me more about this gearbox. Oil wasn't changed yet because opel mechanics said it is not necesary, what is your opinion? Do I need to change oil gearbox filter?
Possibly, yes. but it would have been really hot. There is a flywheel in between the torque converter and the rear main seal that would act like a heat shield.
Hi, could you tell me the tooth counts for the various parts of the Ravigneaux gear set please? If you don't mind I'd be interested in the counts for the other main gear parts too please. Thanks.
Ok, this video is 6 years old, I get it. But I have this trans in my 2018 TourX and I want to do a drain and fill. Is the GM AW-1 trans fluid the right stuff? GM dealer says the only use Dexvi. Thank you!
Dear sir. I can ask you about this issue. I do not know how the oil in the automatic transimission works? Can you help me? Thank you very much. Looking forward to feedback from you.
WeberAuto Thank you for the reply. So I would expect roughly the same complexity. And roughly the same Reliability if Honda and Ford are careful enough? Toyota is reserving that to its most expensive Lexus, while Honda is experimenting on Accord. Honda is courageous. This is definitely the high ground of technological competition.

As i understand it still has 4 sun gears therefore 4 planetary assy. 2 of the are Simmons and two separate. Only thing is there are arranged in two pairs by merging two planetary carriers into one piece
Hi, no, this transaxle only has three sun gears. One in the simple gear set in the front, and two in the Ravigneaux gear set in the rear. There is no Simpson gear set in this transaxle. Thanks for your feedback!
excellent video. Many thanks
Awesome as always. Any chance of the Ford 10 speed?
Thank you! I am trying to get my hands on a 10 speed, but no luck yet.
great videos!!
Thank you!
Off topic John I apologise.....do you have any plans to make a video about the L110 hybrid transmission from Lexus. I ask because as you know it features a ravigneaux set and it'd be nice to see you do it.
I'll now watch this video! Thanks as ever.
Hi, yes, I hope to get my hands on one, but who knows how long that will take (tight budget). Thanks again!
Hello, thanks for filming such detailed video. I had a 2006 volvo S80 with TF80 -SC gearbox. In user manual it say JWS 3309 (Type 4) oil should be used for fluid change. But in later models it says JWS 3324 (AW-1) should be used. While other car manufacturers using TF-80 series claimed AW-1 should be used regardless of model year, should I use AW-1 for fluid instead? Thanks
Best Regards from Hong Kong.
Thank you! Stick with the Type 4 fluid. To my understanding , there is a difference between the two fluids. Best wishes!
GREAT VIDEO... VERY INFORMATIVE!!!
have learned a lot... THANKS :)
Thank you!
I watch a lot of your videos. Very informative though sometimes too technical for me. I always prided myself in doing much of my own car maintenance but as I get older these transmission are getting more complicated not to mention the specialized tools that are needed. Are these 8 speed AISAN transmissions that go in the Toyota reliable. I know they're the next generation of the 6 speeds which have had a good track record.....wondering if the 8 speeds are just as good. Also what are your thought on transmission fluid servicing since many manufactures say life time fluid. Some say every 30,000-50,000 miles....others say follow the owners manual. To me it's like taking a bath in dirty water.
Thank you. I have a complete series of videos on transmission fluids. I also created several Wikipedia pages on transmission fluids. Always follow the manufacturer's maintenance plan. Most drivers meet the severe service requirements of every 60,000 miles for Toyota ATF.
@@WeberAuto I just watched your video about the Toyota ATF history. This was most helpful!!!! And thank you. I noticed Aisin makes WS fluid and says it's synthetic. I also found MITASU makes WS WTF and it's Synthetic but Toyota WS fluid makes no mention it's synthetic and many people say it's not a good fluid. Never know who to believe...Amsoil of course say they make the best fluid...so confusing........do you have any videos on transmission coolers and their effectiveness? Best Dennis
Gracias por gran información es un gran maestro
Thank you!
I have a 2018 Lexus, I just tore my transaxle all apart, but there are no yellow stickers so I am lost. Can you help me put it back together?
Without those yellow labels, there is no way to reassemble it ;) Have a great day!
I rented a 2017 2wd Ram 3.6 v6 with the 8 speed. Before I drove the truck. I thought 8 gears was to many. Now I wish my 2016 F165 (F150 with 2.7 twin turbo v6) had one. It also shift a lot better than my truck.
Thanks for your feedback! They do drive nicely.
The ram comes with a german ZF unit which shifts really nice.
Does the 2017+ Polestar Volvo S60 (362HP) use a variant of this transmission ? The likely candidate is the AWF8F45 since it can handle 480NM.
Yes, it uses the TG81-SC, the same model as the video
Great explanation. Thanks
Glad it was helpful!
thanks for upload.
Thank you!
Thanks for well explaining the function of the gearbox, but the way I want to know how reliable is the puretech 1.6 engine and it using the wet timing belt or chain?
I have a question about this type transmission . My BMW F46 220D LCI is matted with 8 speed AISIN GA8G45AW and I cant find info about interval service ( transmission oil change ) . The car miliage is about 78k and everything is ok but I am dont believe about the life time fluid statement. So what your opinion is about transmission interval service ?
I have problem with same gearbox on 70k km, 6 years old, Transmission too hot alarm triggered once. BMW dealer never changed oil in transmission and they say that changing oil will not solve problem. I am still waiting from them what to do next with gearbox. Any advice is welcome
@@versys23 After detailed research my advice is to get over 10 liters transmission and make two-three standart changes. Oil temperature must be between 35-45 C and don't sent info to transmission comp " oil changed ".
I got information from authorised Bmw service where I bought the car that Aisin gearbox needs to be changed on my own expense around 7500 euro. Dissapointed with Bmw Tomic Croatia and their behavior to client. I will try to seek my rights since I consider that this gearbox is fraud if it needs to be changed on 70 000 km
This is why I don't like CVTs and e-CVTs. Planetary gearsets are the way to go! 🤤
Amen, amen and AMEN! For they try and try with all kind of technical scenarios-DCT's and CVT's etc; but NOT one of them can equal (not to mention "better") a standard planetary transmission when it comes to automatic transmissions IMHO.
Yes the others are cheaper to build (especially CVT) but a nightmare to fix them.
For what it's worth.
Have you watched his videos on eCVT transmissions. Relatively simple and not the same as a standard CVT
This is some great content!
Interesting video. Slightly off topic question. Toyota usually uses Aisin transmissions for their cars. Toyota has always had a good reputation for reliable automatics. How come the European cars that use the AW55 transmission are considered to have weak transmissions? The AW55 does not appear to be used by Toyota but it's still made by Aisin.
Toyota typically renames the Aisin transmissions they use to a Toyota designation. I do not know if Toyota used the AW55 because I don't know what they would have called it. Aisin builds great transmissions, but they have not been without some failures. Additionally, vehicle manufacturers pick the Aisin transmission they want to use. Maybe they picked a model that was not the best pick for their vehicle for some reason (typically $$), i don't really know. Best wishes.
WeberAuto The AW55 had features such as the clutch disengagement at rest in D and the super smooth shifts (when working properly) that were matched to small Luxury cars. I understand firmer shifts at better for long life? Thanks for all your videos
Thank you!
@@WeberAuto I believe Volvo used to have problems with AW55s because of "neutral-drop" and other software behavior which put too much stress on the internal components. It was a case of "a good deed never goes unpunished". I believe they were trying to save fuel but overcomplicated the functional behavior of the unit ... which might be a clue as to why other brands' Aisin boxes have lesser reputations.
thank you for the knowledge
Great job 👍
Nice to see this video, just wondering if it is possible to retrofit this gearbox to 1.9JTD 16V (1910cc) engine? I am not sure if it is a M32 or C635 manual gearbox now on my car, but would really like to get this gearbox on it.
What signals does it need from ECU or any other component if there is any data for something like this?
I've got a camry with this transmission, i have to say i'm not really a fan. Maybe it's because i have a 4cyl, or probably just the programming, but it will downshift and the slightest hint of throttle input and it cannot pull in any gear. This causes countless shifts for even a short drive.
Thanks for your feedback
I would rather have easy downshifts than very late and reluctant (and usually jerky) ones in my 2022 Mazda 3. The car is tuned to try and adjust the torque converter as long as possible before downshifting, but it usually ends up lugging the engine and ruining throttle response.
That's what happens when you have too much overdrive for the engine's torque output. This transmission is a dream in Volvo T6/T8 vehicles.
Even BMW uses this transmission in its fwd vehicles. Oh man, Never thought that I would use fwd and BMW in one sentence
I believe bmw uses the zf 9 speed trans. for its fwd vehicles isn't that correct?
Small wonder CVT transmissions are so numerous. About 8% of the number of parts to these designed correctly. Cheap is the go-to route for new vehicles.
always interesting ...
Thank you!
John, you mentioned an extra solenoid for auto-stop engines. What does that solenoid do? Is it something to do with the restart of the engine/torque converter clutch?
It is a strange little piston type pump to keep the clutches applied with the engine off
Thanks John.
Good afternoon. I'm terribly sorry. I understand correctly - the GA8F22AW gearbox and the UA 80E gearbox are identical gearboxes with different hydraulic units?
EXELENTE VIDEO DESDE PERU.
Veri good professor.
I've got a some questions, but as always your videos are very good. You touched on 3 versions to handle different torque levels, could you eleberate on the 3 versions and how much torque they are good for? I own a 1995 Mitsubishi 3000GT, it's FWD. Latter I would like to modify it with turbos and all that. Right now the car is fun to drive stock as it is, but gas miliage sucks even at the 222 HP stock level. Transaxle is a 4 speed OEM. Do you think I could get one of those 8 speeds to fit in my car? If so, which one is best for higher torque levels that would fit in there? Also, do you know of any 7 or 8 speed AWD transaxles that may be made to work in my car? Thanks for your time.
Un gran video y muy esplicativo dada la complejidad de la caja .
Un saludo desde España
Thanks for watching
Waiting for my Volvo V60 to be delivered, I had to watch this.
Great video, thanks.
... But now I cannot get out of my head trying to figure out how many reverse gears it could deliver... In theory of course?
Good question. I do not know
hello your video is super well explained. I would like to know if we can use the pressure control line to connect a drain machine?
Great video John, but from around 25:30 to 26:00 you're describing the front gear set with the sun held, carrier input, and ring output. How is this not producing minimum forward overdrive from this gear set?
Thank you! Great observation! A single pinion planetary gear set would have an overdrive condition with the sun held and the carrier as the input, but this is a double planetary carrier gear set. It reverses the direction of the ring and slows it down. The formula is Wa=1/((Na/Ns)-1)/(Na/Ns) where Wa is the speed of the annulus gear (ring) and Na and Ns are the number of teeth on the sun and annulus gears. Na = 78, Ns = 38. I hope that helps. Have a good day!
I have a 2016 Chevy Malibu 2.0 with a 8 spd transmission. I see Raybestos makes stronger clutches. The diff is open but these trans are used by other manufacturers like bmw etc. wonder if I can take a LSD diff from a bmw and put into my aisin GM 8 spd transmission
would love to se you make a video on the ford kuga/escape phev ecvt gearbox
I did a few years ago ruclips.net/video/hHU5xFOBcsU/видео.html
Very good video, thank you for that. I've still got a question, in my 2021 Citroën C4 is an Aisin 8 Speed Transmission mounted. When I am in "D" Mode, the car is not crawling very well at very slow speed with the brakes applied. But, if I switch to "M" Mode, it's very easy to let it crawl with brakes applied. What is the difference between "D" in first gear and "M" with first gear?
Internal fluid pressures are increased.
@@WeberAuto thank you.
Same “problem” with 2021 Peugeot 5008. I had the eat6 in my older 5008 (2018) that was perfect. This gearbox is really not suited frictie car. Also very strange noises in 5th and 7th gear at light load. The crawling in stop/start traffic drives me nuts… it looks to be the torque converter I guess..
I like watching your channel. It’s really professional and useful. I was just wondering if the Aisin transmission is torque converter type or not ?. Thanks.
Where can I read about the AISIN 8 Speed FWD in my 2019 VW Golf ?????
What is the most common problem with these boxes? I've been reading there was a lot of issues on Bmw X1 and X2 models, mostly replacing the whole gearbox.
Any particular reason why bands have fallen out of favor? I read an SAE paper by Aisin claiming their modern double-wrap bands have lower drag losses than an equivalent clutch pack and have just as good controllability/response
Hi great info on this video. I have a 2016 volvo xc90 with this transmission. There is slippage when transmission is cold my Volvo main dealer says there is nothing wrong. Should this transmission slip? Many thanks.
since no one replied you, yes it is normal on those tranies, they do that until the gearbox hits an certain temperatur, dont think you should floor it before the engine and tranny has been warmed up
I have a question let’s assume a vehicle drives at 60 mph and the ECU changes gears from 4 to 5 during these milliseconds when disengaging and engaging a clutch what happens in the output shaft and rpm
I have a 2016 Cadillac cts vsport with the aisin 8 speed and when my car gets to operating temperature and in 7th and 8th gear mostly my car will start hesitating. What causes this? I’ve taken it to the dealer several times and they can’t get it to do it with them. Oil and filter been changed 3times by dealer
Sir, I like this video n the 8 speed transmission. But the braking bands had me worried that might break the fluid, produce metal particles n shorten gear life when the bands are taking a greater proportion of the braking load.
Love your videos.....very informative.....I am wondering in your opinion why are manufacturers making it so difficult for owners to service their transmissions? If the 8 sp transmission is used in multiple models why do some come with a dip stick and some not?
Thank you. The answer is simple, today's fluids are better quality and will last a very long time if nobody bothers it or adds the wrong fluid to the transmission. See the Toyota ATF history video I made ruclips.net/video/t73jM6mT8sU/видео.html&lc=UgzXiCE-Slhijah7ykJ4AaABAg and the wikipedia page I created on Toyota ATF at en.wikipedia.org/wiki/Toyota_Automatic_Transmission_Fluid#Toyota_%22Lifetime%22_ATF Best wishes!
grate job thank you
Hello, I intend to buy opel insignia gsi 4x4 209 PS 2019, with 123.000km. In this insignia is aisin AF 50 - 8 3 generation. Can you tell me more about this gearbox. Oil wasn't changed yet because opel mechanics said it is not necesary, what is your opinion? Do I need to change oil gearbox filter?
what an awesome review sir! i hope you make a video about aisin warner aw-1, & does motorcraft dct oil suits warner aw-1?
Technically speaking, is it possible that an overheated torque converter can damage a rear crankshaft oil seal?
Possibly, yes. but it would have been really hot. There is a flywheel in between the torque converter and the rear main seal that would act like a heat shield.
Hi, could you tell me the tooth counts for the various parts of the Ravigneaux gear set please? If you don't mind I'd be interested in the counts for the other main gear parts too please. Thanks.
Ok, this video is 6 years old, I get it. But I have this trans in my 2018 TourX and I want to do a drain and fill. Is the GM AW-1 trans fluid the right stuff? GM dealer says the only use Dexvi. Thank you!
can this possibly mount up to a 5sfe? gonna need the big ol torque rating considering how much that thing will pull at over 250 horse
Now we gonna have a lots of valvebody jobs, broken bands.
Thanks for your feedback!
Can a semi auto car be converted to full auto?
45:00 actually one way clutch holding planet carrier from rotating, not ring gear. Otherwise counter drive gear does not move.
Thanks for the info!
Does this transmission have an oil filter? I did not see you mention or showed us an oil filter?
Dear sir. I can ask you about this issue. I do not know how the oil in the automatic transimission works? Can you help me? Thank you very much. Looking forward to feedback from you.
I will be making a video on this topic this summer, best wishes
How reliable is the gearbox AF50-8, an 8-speed gearbox used in the Opel Insignia? Thanks for the answer
I wish to know more about the 10-speed in Lexus LC500. How many planetary gearsets in it? Four like the Ford and Honda ones?
It has 4 planetary gear sets. It is called the AGA0E.
WeberAuto Thank you for the reply. So I would expect roughly the same complexity. And roughly the same Reliability if Honda and Ford are careful enough? Toyota is reserving that to its most expensive Lexus, while Honda is experimenting on Accord. Honda is courageous. This is definitely the high ground of technological competition.
@@zooplanton Yes, I would think so
