Hello guys i am experiencing an shifting problem with my w204 2011...
When it is in Auto it is like hard shifting between 1 and 2 and also when down shifting it kind of jerks
The atf was changed 5000 km but didnt make any difference..
There are no fault codes in the tcu.
But there is one thing when i make it in Manual M the car start shifting smoothly and also the downshifts are smoother...
nine outa ten shift issues are the results of the shift solenoids find the faulty one via MB DAS Xentry or donate the car
So is there different solenoids for Auto & Manual operations-?
Comfort Mode=C
Mine did something similar after I had the fluid/filter changed at dealer and they updated the gearbox they said, its not bad but now that he mentioned it, I remember. On second thoughts mine are super smooth forward always, only when I am coasting along and it downshifts from 3rd to 2nd, not always happenning I think the speed at reducing speed matters, and it does not happen in sport mode, nothing like this before oil change, so may this sounds like an update-?

Not necessarily.
The facelift was rolled out in March 2011.
Hence there are pre-facelift cars built in 2011.
All 4-cylinder cars before the facelift came with the 5-speed tranny 722.6.

Good to know. Thanks for shedding light on that.
To the OP I say, check/inspect/replace the solenoids and/or the conductor plate. The latter was known to fail on 722.6 units.
March 2011 was the rollout for the facelift models in Germany.
I’m not familiar with the rollout schedule in the USA.
The facelift models could easily be recognized by the dashboard and by the shape of the headlights.
The pics show the interior and the headlight of a pre-facelift.

I got this from Xentry N15/3 Control unit ?? Do you think that the conductor plate is faulty... I check all the solenoid valves it says that all of them are okay....

What were the actual error codes under the "error codes/events" tab? Based on the error codes we will know what needs to be done. N15/3 is only the code of the TCU.

Before you go ahead and change the conductor plate, can you please confirm that no transmission fluid made it into the pilot bushing. This used to be a common problem which would require changing the new pilot bushing as fluid getting into the connector would make the transmission do weird stuff. Had it happen on my CLK. Once we clean the pilot bushing and replaced it with a new one, the problem disappeared.
Search for "722.6 pilot bushing leak" and you will find a lot of info on this. Let's make sure this is not the problem before having to go ahead and change the conductor plate.
