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+

RE-CURING PROBLEM OF THE TRANNY NOT SHIFTING FROM 1ST TO 2ND IN MY R 350. I HAVE TO PULL OFF ROAD, PUT THE CAR IN PARK ( AFTER A BIG JOLT) TO HOPE THAT IT GOES INTO GEAR AS I PULL OFF AGAIN.

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.
When I shift from drive to revers or to park I hear a grinding type of sound and its rough and sometimes I feel the transmission kind of jerk rough.
