2014 W212 Odd or Rough Shifting
- Sometimes in 1st gear the engine will rev all the way to 2,500 RPM and then shift into 2nd. Seems a little high no?
- Shifts are rough, especially from 2nd to 3rd
- Hard jerky shifts when the car is cold.
- Downshifting is very rough, I can feel the car 'jump'
I had none of these problems in my 08 E350 which had a very smooth tranny
Because of this the above issues I always have the card in S mode. I have found it shifts a little smoother in this made compared to E. Anyone else having the same problems?

Lean into it a bit. Dont pull back or try to adjust to what its doing. The computer is doing alot of math =D Give the car time to learn your style, use the same key, dont let your friends/relatives drive it, always use top notch gas.

Get used to it or get rid of it
There is no in between
Good luck

These are signs of low ATF or i believe its time to change your ATF (automatic transmission fluid) because the ATF level might dropped due to gradual leaking from a gasket or it is due to the life cycle of the transmission fluid that just came to its end. Thermal expansion and contraction of the fluid due to temperature flactuations in time it deteriorate its properties. They usually change it around 70,000 miles. Make sure you ask the mechanic and insist on it to use the genuine merceded ATF. If you are unsure call the Mercedes dealership parts depatment and they will be glad to help and inform you which is the right ATF for your transmission. You will be asked for your car chassis number and based on that they will provide you with the right ATF. Do not use any other after market automatic transmission fluid as they tend to cause transmission problems such as hard shifting and early clutch wear after some time so don't take this advise lightly. That can lead to expensive fixes in the future and you do not want that. After the transmission service you should have improved shifting quality. If not it means your clutches inside the transmission are worn and it will need to be rebuilt however i rather doubt it because your car is not that old. Best of luck.
