• Eurocharged releases 55/65 AMG 1000+ horsepower capable 722.6 5-speed automatic transmission upgrades

      With high horsepower M113K engine builds the automatic transmission becomes the weak leak when really upping the power and torque. Mercedes-Benz used the 722.6 5-speed automatic on the 55 AMG Kompressor models as well as the twin turbo V12 65 AMG models because it was their strongest transmission available at the time. It is also the same automatic gearbox Porsche used in the 996 Turbo for the same reasons as AMG as it could handle big torque.

      The good news is the transmission being a fairly straightforward and simply unit is easily upgradeable. Eurocharged released their upgraded parts which they have tested with the W211 E55 AMG and they guarantee capability to 1000 horsepower:

        Very cool. Not a bad price at all either. I wonder if it shifts better...the 5 speed was always kind of soft and mushy...not really a performance gearbox no matter what AMG did to it. I have to imagine that with these mods, it shifts much better.

        It never was much of a performance gearbox it could just take a ton of torque. It's still going to be 'mushy' but handle a lot more power.

        I don't mind the 5-speed personally.

        It does shift better, and then we tune the TCU and you are all set!

        Is this price just for the parts?
