Hey everyone! First of all sorry for my English. I have a little problem with transmission jerking on first gear, for example in traffic jam. I wil try to describe it- when the car is moving at at minimal speed (5-10 km/h) on the first gear, when I add gas- the car jerks (twitches) and then the transmission shifts to the secon gear( the shift is smooth). In all other situations the transmission works great, for example on a high way. The scanner shows that I have a latest version of Tcm calibration. I have this problem for 2 years and cant solve it. What can it be?
