I have a 2019 S63 and am struggling with the Transmission performance and I think we share the same Transmissions. Trying to improve the stock transmission which is sluggish, lazy, dead spot, clunky and requires almost flooring it to get the transmission to "wake up". I have taken to dealer numerous times and am told that's an AMG and your Transmission is in spec..

I think Weistec's TCU Tune might improve this problem.

Anyone have experience with this product and did it work / help?

Thanks all.

I would also be interested to know what your experience is with tuning the transmission

What mode are you in? Sport+? I have the same transmission in my 2019 C63S and it's anything but lazy and sluggish. However, I also mostly drive in manual mode. Nothing beats shifting the gears yourself if you want action. In Sport+ under full throttle it yanks the gears and kicks me in the back. Race mode, which the S63 doesn't have is even better. Unfortunately, the S63 is still more luxury than performance. Both the E63S and C63S have Race mode. Same transmission hardware, but different programming between these cars.

TCU tune will absolutely wake your transmission up. I absolutely love mine, Sport is harder, Sport + is a wild ride.
