Well, I am asking for help about my transmission, but looks this is the first time it happens to one Smart fortwo, nobody knows about this problem, My problem is that not even Mercedes Benz service, knows about it, I was at a dealership and they start changing the actuator for a new one, then the rpm sensor and so on, I decide to try in this forum because they will replace the rest of parts for a lot of money and the problem will not go, I will try by myself according to my criteria and let's see what happens, If somebody knows about this problem, please let me know how it was solved or try to work together to solve it.
Thanks guys
