As for rough downshits - my E550 has developed a rough 5-4 downshift when the car (and the weather) is cold in the morning. The various MLs listed also had some rough downshifts like the 2-1 or 3-2.
Thanks Yazovets. Glad to hear the clicking is normal.

Is your hard downshift while accelerating or decelerating? Mine will happen regardless of temperature, and it's when accelerating.

I spoke with a transmission mechanic today that said when comparing the 7 speeds to the 5 speeds, often the 7 can have harder downshift because it can drop 3 to 4 gears as opposed to the 5 speed which might drop only 1 or 2. He didn't sound that concerned but he didn't see the car. He will do a diagnostic for about $100.

Thinking I might bring it to Mercedes to give me their opinion. I assume their diagnostic will be in the same ballpark price wise.
