Hello! I have just read through the forum and would like to describe my problem now. Most of the time my wife drives by car and also with a lot of city traffic. It usually comes to the problem if I want to overtake another car, or drive on the highway and speed up. I give gas and it does nothing, except that the speed shoots into the red area. It switches into the idling. I go down from the gas and notice how it plugs in again. When I give back gas the speed goes up and he bangs in a gear that I think now drives the engine and gearbox without a car. GT oil has been exchanged and software updated. What do the experts suggest??? Thanks LG Robert
