Before I talk to my dealer, I'd like to get an idea about how the AMG "SpeedShift" transmission should perform - in terms of how fast it changes gears.

I find the shift from 1st to 2nd is very quick. During "modest" acceleration, it shifts from 1st to 2nd without any noticeable lag; I couldn't ask for anything more!

Going from 2nd to 3rd (and 3rd to 4th) is totally different - it's like a slush box, taking quite a while to get into gear.

The above applies to both automatic and manual modes.

Is this typical? Does the "Speed" in the SpeedShift only apply to the 1-2 shift?

LOL! Speedshift is nothing more than 2 more electric switches to change the gears. Even the gearshift is electric.

It's a little bit more than that. For starters, gearshifts are supposed to be faster than the regular MB slushbox. And the software behind those "2 more electrical switches" is a lot more sophisticated than in many other a slushbox, which should make it react faster and more to the point (adaptive).

It's still a slushbox though, no argument about that.

Yeah, I know it's supposed to be quicker but my butt dyno and my G-Tech couln't tell the difference.
