There is only one place for the oil inside the MT82, so however you get it there it will be in the right place. The risk when using any of the "not the fill plugs" is that things come adrift inside the box which cannot be put back where they should be without a full strip down. For that reason it is advisable to spend a little extra time and trouble to identify the "this really is the fill plug" plug before you start.

There is certainly no need to drain and refill because the oil when in through the wrong hole.

Interesting fact Blackwolf, (thank you as always for posting useful info such as this ) just out of curiosity and checking info I had, I had a look at the link above and cross referenced it with the torque settings I had.
The details I had would have came from the WSM for the MT82.

The fill was 35NM, which matches both the info I had and the link.

However, the drain I had listed at 50NM, the link is 35NM.

So in light of that I’ve listed on my notes that I keep for fast accessibility as both being 35NM, which I think is safer. (Perhaps 50NM was stated due to Defender going off road?) but 50 does seem a bit excessive.
There are a lot of discrepancies for sure in the WSM.

Alloy wheel nuts is another, I’ve seen 130nm, to 131nm to 133nm.
I use 133NM, always have but I’ve seen conflicting info a lot. $W33T $0U7H3RN $UG4R

It is hard to understand why this should be so!

Not really, Blackwolf, it's LR. They either cuffed it, or in 2011 they made the bloke who was JLR Gearboxes Head of Dept redundant, (despite his 30+ years of experience and only because he preferred wearing a brown work coat to the LR liveried uniforms), and replaced him with some spotty youth - solely because he was straight out of uni with a MSc in Mechanical Engineering, but who'd never touched gearbox fluid or seen the inside of a gearbox beyond a CAD Drawing.

When asked to check the files by the 'manuals dept' upstairs, said youth discovered that they were handwritten on paper, and not filed in a computer. Unable to cope with this shock, and unwilling to look through a boxed paper filing system (as his priority was leaving on time that evening for a weekend 'foodie' break to Copenhagen which he would share with everyone on Instagram), youth called the previous HOD, and the old boy, tinkering away at home in his workshop, said "it's 2.2 for a 2.4".

Later that afternoon, and whilst prepping for his Long Weekend away, youth typed an email on his smartphone to the equally spotty graduate-entry youth (degree in Fine Arts from York) in 'Manuals', but still foggy minded from the morning's events, and writing one-handed as he waxed his moustache, wrote 'it's 2.4 for a 2.2'.

And, as is the wont of many a youth these days, neither saw fit to 'measure twice and cut once', because the computer would (should?) have surely double checked it for them, no? Hence it went from 2.2 for a 2.4 to 2.4 for a 2.2. Simples.  Monsieur Le Grenadier

Hmmm... Interesting thread. I just want to run a thought past you all.

The "Not filler plug" appears to be higher up the side of the gear box and the "Filler plug" much lower down.

Could the correct oil filling process be:

*Remove both plugs.
*Drain old gearbox oil and replace sump drain plug.
*Top up with fresh gearbox oil using the higher "Not filler hole"
*When fresh gearbox oil flows out from the lower "Filler hole" stop adding oil
*Replace both filler plugs

I've not changed the oil on a MT82 so and am just trying to figure out why there would be 2 filler plugs?

Obviously the above notional procedure could be for when the gearbox is mounted in a vehicle other than a Defender.

Question - When the 2.2L of fresh oil have been added what's the gap between the oil level and the filler plug hole?
