damn, thats too much! a stock slk 55 is really more than enough for the street and daiy use. and in autocross you dont need that power, i remember i used to get my Mroadster , 1 and 2 . seldom i was using the 3rd gear!

Can the 7 speed transmission handle this power???

jikjak

hmm thats a good point
i hope it can coz i plan on gettin the charger

I strongly feel you would have to retrofit the five-speed transmission to take advantage of those power levels. Either that or you are going to be running through tranny's left and right. That is unless you know something that Mercedes' R and D department does not.

No, which is why none of the current supercharged AMG 55s have it.

The 7 speed is currently in the SL500 and the S class weighing nearly more than 600 lbs and 1000 lbs than the SLK, respectively. For the limited edition AMGs retooling costs may have been a factor in limiting the current production to the 5 speed. Let's see what happens next year.

Brandon @ Kleemann

The 7 speed 7G tronic transmission (722.9) is slowly being phased in to replace the 5 speed (722.6) transmission Mercedes Benz has used for the last 5 years. All N/A V6 and V8 vehicles are now being built with the W7A 700 variant of the 7G tronic. The WA700 variant is endurance load rated by Mercedes Benz at 760 nm (560 lbs/ft) of torque. This means the transmission will handle this amount of power continuously with out failure. There will never be a time where one can develop this kind of power continuously on the road. Momentary load ratings are easily 35 % higher than continuous ratings. The 7G tronic transmission will easily handle the performance from a KLEEMANN conversion. The 7G tronic has been available for nearly one year and KLEEMANN has modified many of these vehicles. None of these modified vehicles has had any trouble to date, many of them having logged in excess of 40,000 miles (64,000 km).

SLK55 AMG will come with the WA700 7G- supercharged cars, as mentioned, do not come with the 7G- yet. From what I have been able to gather the reason for this is that the Ravigneaux planetary gear set is the concern for huge shock loads. AMG SC EGS shift programs can be pretty abrasive (hard) on up shifts, the concern is the secondary, or "short" planetary gear in the Ravigneaux gear set may not be able to handle the shock load of 600+ lbs ft on a 4300 lbs car. A SC specific variant is planned- with longer (larger area) short planetary gears. Introduction date is unknown to me.
