AMG 63 2016 (M157) - Noise when accelerating...

My S63 certainly didn’t have a torque converter.
 
Interesting notes, have I got this wrong I thought the amg 7 speedshift transmission on the w212 e63 does not have a torque converter ? Instead having a wet clutch...

That is correct for the W212 E63. I have the S63L W222, my transmission is 722.931 which has the torque converter, only learned of this when I was shown the notes.
 
^ My W212 E63 has the 722.931 transmission as well as your W222 S63L.
No idea if it has a torque converter or wet clutch:dk:

MB EPC shows that yours is a wet clutch when I put in your VIN number, the torque converter also is there but grayed out and says not suitable for this model, really weird because we have the same transmission, must be different variations for different models.

My understanding is the W222 S63 AMG had MCT-7 from launch and the US W222 brochure shows the S63 AMG having MCT-7 from launch - so I would be incredibly surprised to discover any model year having 7g-tronic instead of MCT-7. The S65 AMG however got 7g+ (7g-tronic but the last version of it before they went to 9g) so I wonder if this is the cause of the confusion?

The heart of the new S 63 AMG 4matic is its handcrafted 5.5-liter biturbo V-8. Increased fuel injection pressure and turbo boost quicken its pulse, and that of its driver. Output reaches a new high of 577 hp and 664 lb-ft of torque, while its 0–60 time shrinks to just 3.9 seconds.4 A new lithium-ion battery and strategic use of carbon fiber in the predominantly aluminum body help cut nearly 220 lbs, for a class-leading power-to-weight ratio. The 7-speed AMG SPEEDSHIFT® MCT transmission incorporates a wet startup clutch. A paddle-shifted Manual mode is one of three selectable shift programs, offering 100-millisecond upshifts, as well as rev-matched downshifts announced with a snarl of the AMG® sport exhaust. Logic-controlled flaps in the rear mufflers open to release a more emotional growl under acceleration, and close to mellow out the sound for calm highway cruising.
