2006 Mercedes-Benz R500 Problems

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.

Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.
