I just bought a '95 V8 Discovery. The engine runs like a clock.
I can't get the Disco to move. Shifting gears and moving between Lo and Hi feels like positive shifts but no power gets transferred from the engine to the gearbox.

The the transfer box and the gearbox engage on the driveshaft. I tested this by pushing the disco backwards and forwards and selecting the gears. With the transfer box and the gearbox in neutral the Disco runs free. With just one the transfer box or the gearbox shifted into gear it still runs free. Then I select Hi or Lo and any gear on the gearbox I get the resistance from the gearbox and transfer box on the wheels.

Any ideas or anyone ever experienced this?
