My 2011 107 semi automatic model is having shift gear problems, it changes fine going up through the gears but then won't shift down the gears when necessary? Took it to a professional auto electrician and it came back with a code which when I enquired directly from the main Peageut dealers, it came back as a speed sensor, which was replaced but still the problem is present. Can anyone please help, has anyone had this similar issue and if yes what was done to fix it.
