Gearbox drain and filler plugs

[Smarto]

Hi all, just started changing all the fluids in the diffs, gearbox and transfer. Now when I was under the vehicle having a look what size the filler and drain plugs are, I noticed that the gearbox ones are hex/Allen key heads. Is this right??

All the others are square drive and I thought the gearbox would be the same. I have looked all over it and can't find anywhere else to drain or fill it. Have I missed something and why would Nissan do that??

Hi mate. Yeah it's a hex key. Different to the others. Better I think than the square drive
