Answer
Hi Hub,

The fill plug is underneath your Disco, just behind the oil sump.  There are two plugs on your transmission, the filler is in front and on the side of the tranny oil sump box.  The drain plug is on the bottom of the same tranny oil sump.

Here is the LR techsheet data to replace the fluid:
