[QUOTE=Ethan]do you make any attempt to match revs on your downshifts? a little blip of the throttle to match that 1000rpm jump as you flick into the lower gear.[QUOTE=Ethan]

I don't think this makes any sense. On an automatic, blipping the throttle doesn't match revs because the engine and transmission aren't diengaged like in a manual with the clutch depressed.

And like many people say, by constantly shifting your auto you are increasing wear on transmissions (several thousand $ to replace) to extend life of $50 brake pads. That said, I will manually shift my 300E sometimes because in D it is too slow to downshift and doesn't hold gear long enough when you are trying to drive quickly in city traffic (where you can't just floor it in each gear because you have to keep slowing down and speeding up to go around slower cars). My other car (Porsche) is a manual and my 300E is the first auto trans car I've owned so it is just a habit.
