Weistec Transmission Tune- 9 Speed for 2019 S63
Trying to improve the stock transmission, sluggish, lazy, dead spot, clunky and gas pedal travel distance before the car "wakes-up" driving experience. Its like the car has a wet-towel on the gears.
Does this Tune help the car hook-up / have a more crisp and less clunky, slammy throttle response?
Thanks all.








But to the larger point about the sluggishness; I've developed the habit of blipping the throttle just like I would when driving a manual transmission before I give it major throttle inputs. Seems to work much better and engage smoother.

A few more thoughts in addition to what I said in the W213 thread. Assuming you are not the first owner, I would suggest you get the adaptations reset, so it starts adapting fresh to your driving style. The previous owner(s) may have been driving like grandmas. I've experienced the 9-MCT in multiple AMG models, specifically the C63S, E63S, GT63S and GT63 S E Performance and I have not experienced what you are describing. Admittedly, I haven't tried the S63, but the S63 never appealed to me as a performance car to hoon around. It's mostly a high speed German Autobahn cruiser, so perhaps the transmission programming is more dull. However, as I said elsewhere I also mostly drive these cars in manual mode. Can't really see myself doodling around in the automatic modes most of the time. I pretty much only let the transmission shift itself when I'm in Comfort mode around town, or just cruising along on the highway with DISTRONIC and stop&go traffic. I've always been pleased how even in Comfort mode around town it immediately starts to proactively downshift 1-2 gears as soon as I lift off so to always be in the right gear to accelerate again. It even skips gears such as dropping from 9 straight to 7 or 5 straight to 3. Something AMG highlights in their press materials. But as soon as I hit an onramp or drive more spirited I activate the Individual mode where I have set the transmission to M. Love the AMG Drive Unit for this purpose to switch modes directly from the steering wheel.
For a final thought, the transmission does adapt to your driving style, so if you start driving dynamically it will respond with much more dynamic shifting. Since I only use the automatic modes for moderate driving, mine has adapted to my around town driving style quite well and I try not to mix my moderate driving style with my spirited driving style to not confuse the adaptations, so that's another reason why I do all my spirited driving in manual mode and leave the automatic modes for moderate driving. But mostly as somebody who has driven manual transmissions for over 20 years I can't really stand the reactive nature of automatic transmissions, therefore I drive it like I drive a car with a manual transmission. I downshift manually in anticipation of my next maneuver, so I'm in the proper gear before I get on it. As good as automatic transmissions have become, they still can't read my mind.
