Manual transmission oil change spline socket?

[iucle]

Hi guys,
I am planning to change the manual transmission oil but not sure about the 1/2"spline socket to use. I just bought a 16mm but it looks like its little wobbly inside, so didn't even try to loosen it to avoid breaking it.
Does someone know what size is it? Haynes doesn't say the size in case of the spline bolt Just mentioned the 17mm alan for some models.
Thanks!

I believe it is an M16 spline but anti tamper so has the the hole in the centre to accomodate the pip.

Make sure you can remove the fill plug before you drain the gearbox, otherwise you will be in trouble.

Thanks a lot desertstorm! The. I've got the right one. Just wasn't sure as it wasn't 100% in the bolt. Will try doing it tomorrow,and will loosen the top one first.
Cheers!
