One thing to remember!!! see the guys in here who complain about the w220's. you drive it hard as it was not meant to be it will break and the repairs will be costly! The power they gave you is to pass and so that the engine runs without effort at highway speeds and also to be smooth and quiet while accel. This vehicle was ment for comfort,quiet and class. I do not think the tranny has a memory? I think the active tranny responds to your foot and replies back to all it's components for as smooth a reponse as possible. Let me know if I am wrong? I drive mine very very easy and it will still kick down when needed. As it has always done.If you are fond of relaxed driving, the transmission shifts gears early (at lower RPMs) and tends to use higher gears. This increases driving comfort, helps to save gas and motor resource.
If you love quick starts, rough braking, changing lanes, frequent overtakes, and so on - the transmission holds lower gears for longer periods and tends to switch into lower gear with a slight touch of accelerator pedal, allowing engine to work in higher revs to provide more power. This is good for passionate driving, but it affects gas consumption and motor resource.
It takes 10-20 minutes of driving for the transmission to adjust to your driving habits.
