Anyway, when I started this thread, I was on the fench to get the 2012 C63 AMG. I was over it and enjoying my new ride so far. The MCT vs DCT is not a deal breaker for me as I know the main purpose of getting the C AMG. The whole package is the main thing for me.

So as I learn more about the MCT being inferior to Dual clutch designs in theory. But Why? why would Mercedes put it's design effort on a system that would be referred by enthusiast as less than a Dual clutch design?
Also is the MCT More similar to the IS-F transmission design? I heared that it is a great transmission but still a torque converter.

The MCT is a stopgap solution for Mercedes until their in-house dual clutch transmission is ready for production.

Also, most other companies outsource their DCT trannys. For example, the same company produces the DCT for Ferrari and BMW. All BMW does adapt it to the car and manage the software programming from what I understand.

They already have a dual clutch in the SLS. All they need to do is adapt it for other cars in the lineup. I am not an engineer and have no idea how difficult this might be but they do have one.

I remember that the first year of the E90's M3 DCT had some few problems. Most of it were minors but one major problem (stalling). A software fix were introduced (for several times) to fix those problems.
Is SLS DCT outsourced or in-house?

SLS DCT is outsourced. It's a Getrag unit. It wouldn't make financial sense for Mercedes to use that gearbox in their mass produced lines, seeing as they have a full on transmission production facilities in house that would go to waste.

Good point... however, BMW also outsources its DCT to Getrag. Bottomline, is Mercedes is behind the competition on this in a meaningful way. Maybe that doesn't matter but they really need to catch up IMO.

They really need to catch up big time. The DCT has been in the BMW M3 since 2008, E90's series. Maybe MBZ don't do this change during series model. So probably, the new C AMG will have DCT.

One of the main reasons that MB was so slow to introduce a dual clutch gearbox was because of fighting with unions, who should get the contract to build the gearboxes. At one point, MB was so fed up they were ready to close the transmission facilities and just use Getrag boxes.

So Choy... after living with the MCT for a while, what are your longer term thoughts vs the M-DCT? From all reports it isn't quite as good but is very capable nonetheless. Thoughts?

incomparable... dct is dct, mct feels very similar to the current trans on 08-11 c63.
if you love the 7g tronic, you will love the mct. if you prefer manual, dct surely wins.

For now, I am satisfied with the performance of the MCT considering that I am still in break-in period. The trans is still in C mode until 1K miles and I only managed to clocked up 250 miles. I am sure that I will be even more satisfied the moment I pass the 1K break-in period.
Maybe it is not as good as the M-DCT but it is very capable, or shall I say, way way capable to its task at hand. Definitely, it is better than those normal auto.

Maybe that is why I like the M-DCT. The M3 with M-DCT is my first auto (it is blasphemy in the M3 world to say auto, they prefer to call it automated manual) that I bought. I been driving an MT for a long long time.

That said, the M4's M-DCT is definitely jerky but it also does exactly what you tell it to do when you tell it to do it and doesn't mind being driven manually 100% of the time.
My question is, will this upgraded MCT with the "AMG drive unit" computer be the DCT's equal finally? I hope someone who has a C63S Coupe can tell us (not sure if the sedan has the same tranny/software).
Anybody?

So dusting off this thread, 4+ years later it would appear that the MCT is NOT a stopgap, but rather Benz's plan for its daily driver cars. They're arguing it's for comfort and efficiency, but then in the GT they use a DCT.

Maybe try asking your question in the W205 C63S forum.

There can always be an update available for any module in the car one would just have to check and the only way to do that is with a star diag and a daimler account or a friendly dealer/indy that has those 2 things. Its like checking for updates on your computer, in my opinion updates exist to improve but in the dealers mind, if its isnt broken dont update. You would be surprised at what modules have updates available for them.
