Transfer case oil change- 1999 Land Rover Discovery II
No need for a diagram, to drain the oil, there's a drain plug on the bottom of the transfer box, under the handbrake drum. To fill, the fill plug is about in line with the centre of the handbrake drum and to the left. I think both plugs are 1/2" square. Fill to overflow with Texaco Multi-Gear 75W/90R. Takes about 2L or so.
