After an hours driving today in my 2010 lv diesel automatic, i went to slow down and all hell broke lose, the car almost stood on its nose as it changed down to 1st or 2nd and the transmission malfunction warning came on. i pulled over and had a play and found the car, in sports shift, only showed 2nd and 5th gears, nothing else. I turned off for about 30 mins, restarted and all was good again, but on the way home, again after about an hour, same thing. Its also very jerky in lower gears as if its not sure what gear it wants. Any thoughts?
