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+

Maintenance indicator reminder in the dashboard. Noticing slight hesitation on changing gear in my automatic 2006 R350
I experienced this same issue after driving a period of 30 minutes or more. The car became sluggish and would not easly pull off after stopping at a light or stop sign. No service lights or check engine lights came on at all. It happened once and did not occur again untill several months later. I took my car in for normal mainteance servicing and no problems were detected at all. That same day I picked up my car it occured again but this worse. I could not drive up a hill and something smelled like it was burning. I had it towed right back to the dealer and complained thinking there was a problem with my recent service. That's the only way the problem was discovered and I was told there was a problem with a module in the transmission. I asked why there were no previous warnings or identifed during servicing and the advisor stated that check engine light will not come on untill there have been three repeated occurances.

Same transmission failure coincidentally RIGHT after the warranty ends. 60k warranty? That doesn't sound reliable..... Dealer said it needed a WHOLE NEW transmission and charged $7500 for it. I have a feeling they robbed me, it was most likely the conductor plate and valve body, what the hell did they need to change the whole transmission for at 60k. They don't sell the parts to fix it so I had no choice, Mercedes are robbing thieves they cheaply and poory designed their new cars to fail right after the warranty, only the extended warranty people who fork over the cash in the first place get to have a Mercedes that can drive over 60,000 miles. They don't even have an edge on other imports nowadays, I hope Mercedes gets sued and bankrupt.

ROUGH SHIFTING IN TRANSMISSION. HAVE BEEN COMPLAINING TO MY DEALER FOR A LONG TIME. I HAVE A EXTENDED WARRANTY IN EFFECT.
Experienced some issues shifting into 1 or second gear. Then suddenly the engine stopped during driving and would not start. They car is still at MotorWerk in Barrington and we have no idea what the damage is going to be.

The transmission failed completely. It sound like a major mechanical interference in the transmission and then the vehicle would no longer shift into any gear except park. The dealer diagnosed it as the electrical contact plate and said they would pay for the part and i would pay for the labor $650. After replacing the part the realized it was an internal issue and the transmission needs to be replaced. Still waiting to hear the final solution from the dealer and whether Mercedes Benz will cover this vehicle since it only has 65K on it and it is only 3 months out of warranty.
