Hi everyone I currently own a 63 plate Fiat Panda Twin Air Automatic. Milage:63000 miles. The problem I am having is when the the automatic changes gear from second to third it sometimes makes a cruching sound. I did have a engine management light come on and the gearbox went into netural whist moving and had to stop and restart the car for the gearbox to work again. I'm a total novice on cars so any help or guidance would be much appreciated.
