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.

After many miles of transmission problems, it finally failed and solenoids were replaced for $1100. Three months later, the transmission failed again due to clutch plate and other parts. This time, a new transmission was the answer. Thankfully, I have an extended warranty. At 75000 mikes, I'm over $10,000 in for repairs. Ridiculous and inexcusable.

sometimes holds second gear at 40 miles an hour making it hold in the 2000 rpm range instead of the 1000 rpms it should be at. Happens intermittently but often. Has lowered my gas mileage to 16 mpg from 20-25
