    You could fit an Ole controller, but you'd need a stand alone ecu for the engine with that. The ole controller lets you adjust line pressure which is what affects shift firmness.

    Or you could fit a 722.6 from the V8 or v12 AMG, you would just have to swap the bell housing if you have an inline engine in your W202, otherwise your stock bell housing will be fine. The AMG V8 & 12 722.6's have loads more clutch plates so they are much stronger but actually I'm not sure if the shift firmness would change as you would have the same line pressure..

    I wouldn't doubt that the s class cars ecu is set to shift harder

    I upgraded my w202 722.6 to the 722.643 due to the hp increase

    722.6 has limits of close to 700hp/tq, your stock tranny could easily withstand the extra power from the HPS system. Which car uses the 722.643?
