Hi guys. I've been searching all over internet, wikipedia, forums, etc... but just cant figure out if my transmission is a torque converter or an MCT. According to Data card and WIS, transmission code is 722972 06 706284 and VIN is WDDWF6EB6GF373062.
Yesterday i removed the auxiliary pump (did an oil transmission flush with 236.15 spec oil) and checked that there is a drain bolt on the "torque converter" but honestly im not sure if that may also be a multidisc housing drain bolt.
Very apreciated if someone can solve this mistery for me.
(keep in mind, it is not the exact same procedure or oil spec as they are different vehicles to yours, I linked you this so you have an idea of what to expect)
^Just to make it extra clear, the 7G tronic was later changed to 7G tronic plus (what you have), the fluid required is also different (can tell by the colour).

Thank you so much my friend. Finally a clear answer. Its a 7G tronic plus with torque converter. As for the fluid, it uses blue one 236.15.
Do you have any webpage to get this exact info? I couldn't find anything.
To answer your question, the one you listed is correct as well, you can use that.
As for finding the information, it is really not that difficult, you could do the same in the future : )
Here is how: There is no better place to look for than from MB themselves. First I based the information on my knowledge that 722.9 7G TRONIC plus came out back in 2010 and the non plus version was discontinue since then. Only the later vehicles like the 2017 C 43 (basically a rebrand of C 450 but with a new transmission) had 9G Tronic and 2018 C 300 sedan/coupe/convertible (exclude phev as that kept the 7G). Tronic is MB's fancy term for torque converted transmissions (TCT which to them stand for torque converter technology).

I was a little confussed as i read somewhere that C450 AMGs had MCT speedshift transmissions.
Thank you so much again for the MB class . Really appreciated.
Best regards.
You're welcome but hmmm, do you mind sharing that site you came across with the wrong information, so other members who sees your thread knows to avoid it in the future?

It is a bit confusing. Only AMG uses the TCT moniker. The AMG transmissions are either the SPEEDSHIFT TCT or the SPEEDSHIFT MCT. The latter is only found in the 63 models. The C450 was an AMG Sport model, not really a member of the AMG family at that time, so AMG tuned the existing MB engine and transmission, and it has the 7G TRONIC Plus as mentioned above. The 7G and 9G TRONIC transmissions are the MB variants, and the SPEEDSHIFT are the AMG variants. When the C450 became the current C43 it got the SPEEDSHIFT TCT 9G. The SPEEDSHIFT TCT 7G was used in older proper AMGs starting with the 2005 SLK 55, before they launched the MCT 7G with the 2008 SL 63 and subsequently fitted it to the remaining 63 models. At one point the SPEEDSHIFT TCT was also called the 7G TRONIC Sport

so apparently Mercedes called it that in 2015 preliminarily in that referenced dealer ordering guide, however, when it hit the streets, apparently they referred to it as a traditional transmission, as evidenced by all of these articles on the Internet. There doesn't seem to be any other place after that dealer ordering guy that Mercedes refers to it as a speedshift transmission. I welcome further references to the contrary. Sounds like this was a situation where the "AMG lite" series of Benz models was coming into maturation and prime time and they were not settled on nomenclature:
