C63 DTM AMG

hey guys i know that the sl63 has the much desired MCT transmission but i noticed that the SLS has the DCT transmission. Can someone clarify the exact differences please?

Also, is it possible that either of these would fit in our C63s? If so i would seriously cosider swapping the current transmission out for a much faster one.
Thanks in advance for all of your answers!

MCT maybe because it's just a different clutch in a similar bellhousing with the same planetary set. There's got to be a LOT of different electronics to go along with it though, so it's not really a practical solution.

The DCT is rear mounted (by the diff, AKA transaxle), so that's not an option at all.

You can go on You tube and see the differences between the Mercedes "Speedshift" transmission and the BMW SMG2 and Porsche PDK.
The "speedshift" looks like a conventional planetary geartrain automatic that uses a wet startup clutch rather than the conventional torque converter.
The SLS looks more like a multi clutch split gearbox basically like the Porsche PDK.

If you're willing to drop $15k, I'm sure a lot of things are possible.

well see how much it costs but is there any word of this coming out in the next year or two?

DCT is faster than the MCT. MCT is a newer version of the 7G-Tronic which is coupled to a mechanical clutch instead of a torque converter, thereby enhancing shift speed and fuel economy.
I guess the C63 will use the MCT when it be facelift.

Anyy update on the MCT unit to replace the torque converter?

A press release last year stated the C63 would get more horsepower (p31) but would not see the MCT.

To bad thisbwill never happen. C63 will not get a facelift or MCT tranny. This was said from amg. And plus don't u guys think it would have been in pp2 with tue extra power and stuff the 2010 c63 got?

Anyways I asked my tech and service mang for this if it's possible. He toled me NO. They both did. Good luck

And the facelift and MCT ended up happening. LOL!

Moral of the story... Never say NEVER.

I've noticed the 7G-MCT shifts "firmly", compared to a regular 7G slushbox and to BMW SMG (non-M). I was able to do smoother shifts on the BMW SMG, compared to the C63.

I'm not really complaining; it's just an observation.
