Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Has not been fixed yet. When coasting and the car shifts from 2nd to 1st, there is sometimes a loud "clunk" as it shifts into 1st.
When the car downshifts from second to first, just before stopping, I feel a jerk.
