Hi all,
I'm a new member to this forum. I've recently purchased a W212 2012 with 7G tronic gearbox. It looks like the gearbox jerks when it's cold and not sure if this is a right behaviour.
I took the car to a Mercedes specialist which has carried a service on the gearbox, also removed the valve body assembly unit, checked all the solenoids and everything seems fine. Plugged in Star and no codes stored and also reset the adaptions but still the same issues, straight after resetting adaptions the gearbox jerked in every gear until eventually calmed down and now it's exactly the same as before.
Literally in the morning or in the afternoon, if the car hasn't been started during the day, for the first 5 minutes when changing from 1st to 2nd gear it jerks, especially when going uphill or downhill.
I really need help, as it drives me nuts and not sure what else to do.
Thank you.
