I have an Econoline 250 and I have a problem with the transmission when braking and accelerated again to continue feel there is a difference between the engine and transmission, it takes 1 or 2 seconds to connect the engine with the transmission again, I hear the engine when accelerated but it seems that the transmission is in neutral and take those few seconds to connect to the transmission, only happens for example at an intersection when I have to stop and continue again, someone can help me with this, thank you very much.
