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.Google+

Mercedes-Benz E550 Problem

Very hard shifting from second to first going up hill. It felt as though the transmission was going to drop out of the car. The following day when we picked it up they said they were unable to duplicate the problem. I asked where you tested it, they said around the dealership. I said it happened on step roads in the mountains. They kept it for another day as one of the Techs would drive it home. Well the next day we were told the problem still could not be duplicated, but they got a program change from the factory that same day, right. It seems like it's better, but we only driven it 1,450 miles in the last seven months. The car has not seen the mountains since than.
I truthfully do not trust the Mercedes Dealer Services.
We've had problems's with the AC and the drivers window. As they cannot duplicate the problem they will not replace the inner workings to please a customer.
We have totally had it with the lack of care from these people and that of people at Mercedes Customer Service.

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
