they cost more yes, but not harder to maintain (if you buy quality stuff -> german stuff , not chinese crap). but i was talking about modern automatic transmission, not 20 year old stuff. modern modells are WAY MORE efficient (and as i said even more efficient than anyone could be with manual shifting)
Modern AT transmission needs to be maintained every 50-60k km and have the oil changed
in all it costs about 300-1000eur, done in a specialized workshop/dealership
Modern MT transmission is recommended to change the oil every 5 years, but not mandatory
costs 100-200eur and can be done in any garage with service hole or lift

No modern AT gearboxes don't always shift when it's most efficient. Slamming the pedal and not getting a reaction is not efficient
Only real sportscars and premium line cars have somewhat "good" AT boxes. Of course, if you only drive like an elder, it's all good. And no, I'm not a streetracer
exactly - the praised ZF transmissions, that have hydrotransformator, which means unless you're cruising - 5-25% of engine power doesn't reach the wheels and actual gear switching takes 2s+ - are we still in the 80s?

Who told you that because it doesn't apply to all manufacturers.
I understand you like to shift a manual, but you probably live in a non-traffic area, because constantly shifting between 1-2-3 in traffic would bore the hell out of even the most enthusiastic driver.
I never heard of anyone doing a 1000 euro maintenance on his automatic transmission every 50k KMs. My father drove Mercs for decades bought at above 150K and never did anything to the transmission. These cars had a tough life since he drove 1-2 times a year all the way to Turkey.
Manufacturers also recommend to go to the dealer every 15K or so, does everyone do that?
So you're saying going to the dealer with an AT car is 300-1000 euros every 50K KM costlier than going to a dealer with a MT car? That's absoulte bullshit. I've driven AT most of my driving life, you are incorect.
you misunderstand, you should be going to the dealer without regards if you're driving AT or MT
it's just that every 50k or so km you need to pay 300-1000 euros more than MT
I know the intervals for VAG:
short change oils: every 15k or 1year
long change oils: every 30k or 2years
if you have manual: nothing more
if you have 7spd DSG: every 60k service and oil change

And again, Eagle, you pinpoint only older gen trannies.
that is true, for a 2014 6spd DSG VW claims that it doesn't require oil service
I am skeptical that the transmission can last reliably more than 5 years without oil change, but time will tell
coincidentally not many ppl drive cars over 4yo in 1-st world countries, or don't actually own the cars they are driving, so they don't care about long term maintenance
and car manufacturers don't care about life after the warranty 2-7 years
in the old soviet block countries, average car age is 10y+
different places have different meanings for the word "lifetime"

I already stated my opinion about AT (did I?) but I would like to point out that a "tough life" for a car isn't long roadtrips, quite the contraty, it's city driving. On the road everything works in ideal conditions of temperature, the oil does it's job perfectly, etc. Inside the city things are often too cold or too hot to work properly, and gear changes happen much more often, thus giving a harder time to transmission, clutch, torque converter and whatever.

Except that you forgot about the clutch replacements in manual cars, while not frequent in most cars/for most drivers, are also not cheap... Traditional AT will never have that problem. Dual clutch (DCT/DSG) on the other hand...
Ah, I didn't write what I wanted to say I think. I wasn't talking about the road to Turkey, it's just one long stretch of highway. I was talking about the mountainous roads in Turkish cities.

The manual clutch is very driver specific, my 8yo 105k Polo is still running strong on the factory clutch, but I've changed the slip? bearing for the clutch at around 80k.
It depends on how you drive, do you match revs, do you engine brake, etc.
Basically an experienced driver will have a longer lasting clutch plate.
and about the DSG:
Quote:
... It is a "wet clutch" system so the wear is reduced by friction absorbing fluid (much lower thermal load). The changes are virtually "instantaneous" so slippage and therefore wear is almost negligible...
I'm not sure that ALL DSG's are such, I believe some of them are dry and some wet.
I believe motorbike clutches are also wet.
another interesting quote from a presumed Audi mechanic about the ZF trans:
Quote:
I have mentioned serveral times that sealed for life gearbox's "The proper tip tronic ones", Made by ZF not Audi, used in Audi BMW Jaguar etc, All can have issues at big millages, typicall 100-120 thousand miles because from new the oil and filters would never have been change.
Changing them at every 40-60k or so would have them last much longer.
But don't you worry, the majority who buys premium cars, don't keep them for hundred thousand km anyway. With good lease options, they keep the car 3-5 years, a period of time where you can easily extend warranty.
Wait.. what happens if you don't do any maintenance on your clutch? I guess my fiat still has the first on it and it's at close to 178.000+km If it wears down, can I just replace it or will it break something?
when you accelerate rapidly the revs will rise but the car will not accelerate = clutch slipping
at first it will be very faint and it will just decrease your fuel economy
at later stages it becomes blatantly obvious and will make the car undrivable
you could possibly wear your pressure disk and flywheel (as the clutch is pressed between those 2)
so instead of just changing the clutch you will need to change the whole package = instead of 200eur you will pay 500eur for service
I don't think you can brake anything serious

I recently changed mine, ~200k km. I couldn't engage any gear, it was that bad.
the clutch is a very simple system and usually lasts a long time, same for traditional AT. Americans have been driving AT for many decades, Europeans have MT, both systems are very well developed. Modern types like DSG/DCT/CVT maybe a little less reliable or more expensive to maintain, but can offer other gains. All systems have advantages and disadvantages though...
for economy the CVT is the best, for 'sporty' driving you can't beat a manual, for raw speed DSG is ideal. Traditional AT is a good compromise for normal cars in normal situations.
so how does that work exactly? would owners get compensated, is it US only, i doubt they gonna look for some russian or eastern eu cars to compensate them and how much would that be, will they be able to afford new car or something? sorry i'm clueless
btw I bought a new old car today... It's a honda space ship/8th gen euro civic
1.8 petrol with full kit, it was really cheap but I will probably need a new clutch soon (noticed on the test drive, they made a discount).
The way I see it, every life is a pile of good things and bad things. The good things don’t always soften the bad things, but vice versa, the bad things don’t always spoil the good things and make them unimportant.

I laugh but I shouldn't really...my Yaris is only 5 years younger than the Camry xD
