I plan to upgrade S430 once I get it, but I remember a friend of mine told me that the new 7 Speed Auto can not stand over 400HP or somewhere around there. What is the actual number and is it worth getting the new 7 Speed or the old version 5 speed. Because I read in the Consumerguide website the new 7 speed did a 0-60 in 5.9 and the 5 speed did 5.6

Thanks

The power load rating figure is under 400Bhp for the 7G. However I think a 7 speed in anything more than a 350 is pointless since the bigger engined cars have plenty of torque to keep things going.

If I was you I'd stick to the normal 5speed in the 430.

Thanks for you responds Storm. Its funny that the New 7G Automatic is week when it comes to upgrade. Im looking for power and if 5 Speed is what you say, then I'll go for it. I should get a pre-owned one and the insurance wont be that high and the price for the car wont be as much.

Thanks

any of you guys look up the 7 speed auto???

well i was reading about this the other day and i found a few sites with info on the 7speed but i can only rem. kleeman. i just copied and pasted from http://kleemann.dk/site/Main/faq

Will the 7G tronic be able to handle the power of a KLEEMANN tuning solution?

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 new 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 64,000 km (40.000 miles).
