Hello,

I am looking for suggestion with my matic problem. My car is W203 C230 (facelift) with VIN: MHL2030525J042044. Current KM is 85.000 (KM not miles).
I have a problem with gear 1 to 2 and 2 to 3 shift/change is not smooth (jerk and sometimes delay) and also when I drive uphill road, I feel like the gear was delay to change to lower gear and make car slow down (sometimes almost stop).
Problem happen either cold or hot.


Here's what I've done so far;

1. SD Scan with no error at all.
2. Change the matic oil at authorised dealer about 2 months ago but the problem still there.
3. Did overhaul and replace B1, B2 and K2 at local workshop (mechanic ex authorised dealer)

Any idea what is happening with my matic and the solution for it? if it is related to TCU but there's no fault from diagnosis.
Since, there no error from the scanning. How to determine the problem?

Someone told that the problem with valve body. Change valve body should resolve the issues. How to to determine if the issue with valve body?

any comment and suggestion highly appreciated.

Do an adoption?

Plutoe

get the guy who scanned the car to re-scan while driving and look at the shift patterns vs the standards

I tried SD adaptation but I couldn’t make engine torque into green zone so adaptation never happened. Even try in uphill road also the same.

how to get standard pattern and which value should I pay attention while driving? I can do screen recording when driving so I can record the Xentry.

Have you tried resetting the shift points?

auahelap

Yes I did. Why is this important?

Scorpion34

Resetting them lets the car relearn where to shift.

auahelap

which one are referring by shift point?

1. The one that I move selector from P-R-N-D?
2. Shift adaptation?

I did the first one. As for the second one, I still unable to do it correctly. I assume adaptation also will will occur after roughly 1000KM.

please advise.
