auto gearbox filler plug and level
Read lots and lots about fluid types and the complex way to fill the auto gearbox with Shell M1375.4 on this and Jags Forum but my question is where exactly is the filler plug. I read here that it is a torq headed bolt but my 2009 has no Torq headed bolt that looks like a filler. The only Torq drives are in the pan plate. Is the filler on the offside or near side. How high up the box ? I am used to manual Disco 1 and 2 fillers but have no idea on the Disco 3 Photo anybody ?Currently running on the farm, Defender 300TDi, Discovery 1 300 TDi, Disco 3 and D4

The drain plug is at the rear of the pan filter in the center (underneath if you like).
The fill plug is on the right-hand side of the gearbox, towards the rear. I reckon it's about 15-20cm up from the pan filter.
It is very easy to see once you've removed the plate from under the gearbox... 2006 Discovery 3 TDV6 SE AutoBuckingham Blue 2007 Golf GT DSG

Level?
What level do you fill it too? is it till it dribbles out?
Is lifeguard 6 the fluid to use?

You need an 8mm allen key.
Rough procedure is:
1) Fill it until it starts to dribble out
2) Start engine and run the gears thru slowly. R,N,D,sport,3,2,1,2,3,D,N,R,P (3 secs between)
3) With engine still running, put a bit more in (but don't get too carried away) Put plug in fully, but not tight.
4) Let engine warm up, till the temp gauge is just on the bottom marker. (fluid will rise)
5) Run thru the gears as per 2.
6) With engine running. Take plug out. Either let fluid drain off or Fill it until it starts to dribble out.

You can see the filler point here straight up from the screwdriver on the side of the box by the gear selector linkage.Mark.

For those who have an iid tool or similar it is safer to take actual live readings of the temperature of the transmission oil as the correct temp to check the level at is quite a narrow window and the engine temperature gauge on the Discovery is a notoriously flakey beast. I seem to recall the temperature at which to check the level was between 30 and 35 degrees C.

The transmission temp will not have a direct relationship with the engine temp - so looking at the engine temp is pointless.
The oil/transmission temp needs to be between 35 and 50 degrees C - so actually a wide window. A cheap lazer temp pointer works well.

Myself and another user have found the coolant temperature to match up quite well with the gearbox temperature. And as you say, it is a wide window so should be good enough for those without an IID
