The AMG SPEEDSHIFT MCT 7-speed, with its combination of wet clutch (versus torque converter) and automated transmission shifting is so different from either a 6-speed manual or conventional automatic, that I just have to ask:

Assuming non-track and non-abusive use, how many miles can it be expected to perform before it needs some form of repair or rebuild? (Beyond the prescribed fluid changes in the maintenance schedule)

Or, do we even know yet?

And, what fails first - the wet clutch pack or?

Jim G

 

287K miles. Maybe 288K miles though depending on where you live.

 

Damn ya'll can't even let this man breathe!! lolol

 

We do not know yet.

 

I've been hearing stories of this failure. 288k miles seems to be the consensus of mass and utterly catastrophic failure.

 

In all seriousness, I'm not too sure you'll get an answer here... Dual-clutch transmissions are still a relatively new technology. Automakers didn't start mass-producing dual-clutch transmissions until the late-00's to the early-10's. Even to this day, most automakers aren't completely sold on the technology. On top of that, not many cars from that time frame are pushing over 100K miles yet. However, to give you SOME information; What does seem to go bad are the controllers and modules telling the transmission what to do. Other than that, I haven't found much on dual-clutch trannies. Transmissions in general, if driven like a human and maintained properly, tend to VERY reliable and SHOULD theoretically last the lifetime of the car.


Why do you ask though? You having issues?

 

I'd say 596k. The MCT is at least twice as slow to engage gears compared to other trans..

Seriously, unless you gonna mod your car and drive like a lunatic all the time, the MCT should be rock solid! I hope!

 

Why are we talking about dual clutch transmissions? The w204 AND w205 C63 do not have a dual clutch.

 

That is encouraging.

Mine went exactly 45,278 miles.

Tomorrow it will hopefully go a few more!

 

Another day, another retarded question.

Do you even think these through before posting? What is the lifespan for ANY transmission before it requires a rebuild?

Can't wait until tomorrow's post, really, I look forward to these peeks inside the mind of someone who is losing theirs...

 

The MCT is not a dual clutch transmission. There are postings here and on Google that describe it.

No, no issues, just curious if we have any idea yet of its durability.

Reason for asking? Check out the track records for cars like the Aston Martins. Their transmissions fail VERY quickly - it's a known trouble spot. I'm talking less than 20k miles there to failure. Although I thought about a used Aston Martin for a bit, I abandoned the idea completely after reading about the transmission failures which apaprently had no cure - you simply paid for a brand new one and then waited for that one to fail exactly the same way. That made the car very costly to own.

I don't understand your comment, Blkrokt. As I pointed out in a post above this one, some of the newer technology trannys fail rather quickly. I just wanted to know what the apaprent track record is on our MCT trannys.

"Do you even think these through before posting?" Yes, I thought it through before posting. Did you think through yours before posting?

"What is the lifespan for ANY transmission before it requires a rebuild?" Depends on the tranny. A 6-speed manual in a Corvette or Camaro, if not abused, lasts a very long time. Whereas when GM installed its automatic in the Chevy SSR with the Corvette LS2 engine, GM had to add code to the ECM that reduced the engine's horsepower in 1st gear because that transmission, installed in the heavy (4850 lb before driver and gas) SSR, could not handle the loading. When I hotrodded the engine in my SSR, I had to buy a built tranny from Phoenix Transmissions, because the stock GM tranny lasted literally only weeks with the higher loading.

"Can't wait until tomorrow's post": I hadn't planned a post for tomorrow, but since you can't wait for one, I may try to oblige. Only because you asked, and I love you so much, Blkrokt.

Uhh.. Where do you get this stuff? My buddy has owned both a DB9 & DBS and has put many miles on both. Transmissions were perfectly fine.. He is the process of actually purchasing another V12 Vantage S. I'm sure every manufacture has had their fair share of transmission issues, but it is definitely not as a big of an issue as you are making it seem to be.

Also with Aston you can get the vehicle inspected at local dealer and purchase an extended warranty THROUGH Aston even if the factory warranty is expired. Warranty is unlimited miles and is just regulated by amount of years you would like coverage. Never seen any other brand do that yet.

Also, if you don't see anything regarding MCT transmission failures it is probably because there hasn't been many! Just saying.

 

Mocking someone with a mental disability is pretty low...

 

The 2nd website that comes up when you google "Aston Martin transmission problems" is:

https://www.quora.com/What-are-the-m...tage-V8-owners

which was posted April 2016. It says (and this is a quote):

"
The Sportshift transmission is an abomination against humanity. It works, don't get me wrong, but it works horribly. Its low speed behavior, especially around town, is horrendous, and downright dangerous, as it mis-shifts or sometimes doesn't engage at all. Aston Martin tells people they aren't operating it correctly, which is absurd, seeing as its a freakin auto shifter. There's nothing to operate. Cars role backwards down hills (not kidding), and first gear doesn't engage correctly.

The clutch is another abomination. They fail, and its a known weak spot. The sportshift and manual use the same clutch, with different actuating mechanisms. Clutches are know to catastrophically fail and take the flywheel with it. Aston of course claims the dog ate their homework as it concerns the clutch.
"

Then there is this one:

http://www.autoworldnews.com/article...n-problems.htm

which talks about the RECALL Aston Martin did on the 2014 model DB9 and Rapide S:

"
Aston Martin has announced a "precautionary" recall of 440 DB9 and Rapide S vehicles in North America due to potentially faulty transmissions in the 2014 models.


Dealers have been ordered to stop selling the affected DB9 coupes and Rapide S sedans, which were produced from June 2013 to July 2014, until they have been repaired, Edmunds.com reported.

The problematic transmission can shift to neutral without warning.

"Due to a faulty circuit board, the transmissions in the affected vehicles may inadvertently shift to neutral without input from the driver," the National Highway Traffic Safety Administration said in a statement quoted by Edmunds. "If the transmission shifts to neutral, the driver will not be able to maintain speed or move the vehicle out of traffic, increasing the risk of a crash."

The recall will involve replacing the faulty circuit boards in the recalled vehicles.

"Aston Martin's commitment to safety and customer satisfaction is paramount, which is why the company is taking this precautionary action," Aston Martin spokesman Matthew Clarke told Edmunds in an email.
"

Just sayin' . . .

You do realize the Sportshift transmission is not a true automatic right? It's a manual transmission with a computer controlled clutch. Look at the F355 and its F1 electrohydralic manual. Ferrari was one of the first to bring it to market and had the same issues.

Nowhere in that nonsense you posted does it say transmissions fail sub 20k miles. Also, that recall is for a circuit board, not transmission failure. Stop clogging the forum with your diarrhea.

 

I never said the tranny was an automatic or a manual.

Check on Google for 2007 =2008 timeframe clutch problems where the rivets in the clutch plates were falling out at a few thousand miles. That problem had nothing to do with a circuit board.

The list of AM tranny problems goes on and on if you look at the available data, across many model years.

TROLL

 

I'm glad I'm learning about how strong the Corvette transmission is, or the allegations against Aston Martin on a c63 forum.

I think Jim should get his own subforum for his musings.

 

 

That's great news, and what I was hoping I would hear. I consider my original question answered.

Jim G

 

Whew! What a relief! Now I can sleep knowing you are satisfied!

 

Seems like just yesterday Jim G joined and we were congratulating him on his purchase and for joining the forum....how they grow up so fast...

 

:-)))
