I think the little gear lever you're talking about is the transfer box selector. It gives you a choice of high or low range plus the ability to lock the centre diff in either high or low. It also has a neutral just like any gearbox. Land Rovers have two gearboxes, the normal 5 speed one and the transfer box. If you're in neutral in either one of them you ain't going anywhere.so if the diff is in neutral but the gearbox is engaged the car wont move??
