Answer
It certainly sounds like you have a clutch pack failure or some other breakage inside the transmission.  If you had access to a LAnd Rover factory level test system - an Autologic or T4 - yo could read the codes from the transmision unit and perhaps get more info but I'd give 9 or 10 odds the transmission has failed internally
