Is the transfer box oil the same as the gearbox oil ?

Gonna change mine when i stick the new mount on and there are so many differing opinions on what oil goes in where. I have seen " the same oil for the lot, gearbox,diffs,transfer " same for gear and transfer, another for diffs and just about every other combination imaginable

diff and gear box different oil gear box and transfer box the same

well thats my opinion

I used same in all of mine

Tis what i mean...some company's are advertising one for all, my local motorfactor geezer was horrified at using the same in the gearbox as in a diff, 1 oil company says that you should use 2 different oils another says 3 ??

Mitsubishi spec is 3 different oils, my local oil shop, advised if I went a higher spec I could use the same stuff

Bizzarly mitsy uk do not agree to using the oil it tells you to use in the hand book !! Anyway i am gonna go with same oil in gear and transfer and different spec in diffs

anyone know the size of gearbox filler/drain plug ?
