I’m not entirely sure you will even need to remove a cross member... when I was under my late D2 the other day I was looking at it for when I drop the auto ‘box sump and couldn’t see why I would need to remove a cross member. There is one under the t’box and one under the engine but none under the auto ‘box... I don’t know if they changed the design but I’m fairly sure that there isn’t one missing on my truck... when you look at this pic, it doesn’t show a cross member blocking the auto ‘box sump either...

There’s a difference between a diesel and petrol, with petrol D1 & 2 the exhaust has to be dropped to remove the auto box sump, which can’t happen if a cross member is below, hence its removal is required. Same with early RR and others with a similar box, that doesn’t have a fill plug. :)
 
LR has a history of siting X members in awkward places, as in the case of the series vehicles. Unsurprisingly the Army specified their stock with bolt-in versions of the gearbox X member rather than the standard welded :rolleyes:
 
I still haven’t got round to refilling my box back up yet, been busy.
My box has a dipstick but no filler, I was going to use the dipstick hole.
What was the device from B&Q used to do the refill?
Cheers

Use a funnel in the end of the dipstick. Best not to pinch the one out of the kitchen.......
 
Got round to putting the oil in today, made sure the six retaining bolts where tight and the pan was seated properly.
Put five litres in. Down the dipstick tube. Cycled through the gears a few times and then checked the level. Engine at idle, gearbox in neutral.
Level reads a little low. But was in a rush as weather is awful.
I will recheck tomorrow when I put the cross member back on.
Got to take the old oil to the recycling centre tomorrow as well.
There was nearly seven litres that came out into my drain bucket.
I guess it had been over filled, or does more drain back to the sump when they have sat for awhile?
