Mazda6 2.0 2011 shift shock from 1st to 2nd gear when cold
 

Dear Members
I am facing problem in the automatic transmission of my mazda 6 2.0 2011 Japanese model it is maintined all the time at mazda Service centre. I am facing issue that during gear shift from 1st to 2nd I feel shock/jerck specially when the car is not fully warmed up or cold in morning. but once it is warmed up it works fine. So I want to know that it is TCM issue as it was in older mazda 6 model which required refalshing the TCM or some thing else. Transmission fluid and filter is changed 10000km before. I just purchased one week before and during test drive it was fine as it was already warmed up. what is the solution for this issue. anyone faced this issue or any one know the solution will be helpful.
