Hello, I finally have my Mustang on the German road !! Unfortunately, my test drive has shown that there is still a lot to be done. I seem to be missing the third gear and when I drive the gearbox is very nervous as if the kickdown is pressed or sometimes as if I had an idle. In addition, a zirple comes from the rear axle. Even when I start the engine in cold condition is a bright goat to hear. (Car stands N in place at cold and warm always glei (ch) Could these sounds come from the gearbox? It could have been a bit smooth? Well, that’s why we love these cars!! I hope someone can help me? Greetings and thanks!
