Hello everybody,

Sorry for my english,
I have 12' CLS 63 AMG with 27K miles. I bought it in USA with 24K miles and delivered to Belarus. In our city we don't have official MB dealer so I need your help or advice. When car arrived, everything was normal but now there are jerky shifts in "C" mode (in S and S+ they appeared but more strongly). Sometimes shifts from 1 to 6 gear and from 6 to 1 gear happened with little kick. I'm notice them more when driving before 2000rpm. It's not like critical (passengers do not notice them) but I am as a driver notice that earlier tranny worked much better. It seemed to me, that tranny works better in rain and first 15-20 shifts after cold start, but I'm not sure. The second problem that appeared not often. For example, you driving car, at this moment 4th gear enable, you begin to brake, and after few moments you push accelerator little bit, 2nd gear enabled with big kick and all car shaking.
I was in local service. They have MB scanner. They reset my tranny. It's not help.
Also I contact official MB service in another city. They said that they don't meet any car with mechanical problems with this transmission. They advised me to change oil in tranny. Now I'm waiting for oil.
Do you have any thoughts? I'll appreciate any help. Thank you

 

if a service tech knows how to use DAS correctly he can connect to the TCU in the valve body and there will be certain parameters that can be viewed which will out of the permissible range which is causing your issue.

 

Is it possible to adjust these parameteres? Or need to replace valve body?

Thank you

 

maybe try to disconnect the battery and then connect it again? might work

 

Did this, not help. I'm notice that one day shifts are much smooth and another are jerky.
I'm waiting for tranny fluid change then i'll let you know

 

Ok, I changed fluid with filter, gasket and bolts. Didn't help. (( I'm noticed that when is car "cold", tranny works first 20-30 gear changes good, than all gears changing with jerk.

 

how are your transmission mounts?

 

might be conducter plate

 

Hello again! What battery I should disconnect? Under hood or in trunk?

 

Don't know, I'll check

 

I was in business trip for 17 days. I left car in garage. When I returned back, first 2 days gearbox worked close to perfect. After 1 week of driving the same symptoms began to return.
