Judging by the trace of oil coming down from the drain hole where the R380 mates to the 230, I'd say you probably have a leaking intermediate shaft seal also (or it may just be this...)
 
it's silly to apply rtv like that. you need to remove the part, clean off old gasket and apply a thin even layer. thick enough to fill imperfections, thin enough to not squeeze rtv everywhere when you tighten it up.

however, the lt230 is filled with ep90 and that is red gearbox oil (atf).. so looking at your initial post of you replacing the oil.. you've filled it with the wrong thing (if it was red atf).

i'd step back and make sure you are clear on what you are doing before you completely feck up your gearbox and transfer. :)

btw, atf is a lot thinner, so that probably why it's leaking worse.

Thanks I am not a complete idiot I know the difference between ATF and EP90, the original post was what we thought was a TB leak - presumably it had MTF in before. Now the gearbox has ATF it is clear that it is the gearbox that is leaking somewhere and not the transfer box.

By the way, the plate was removed cleaned etc before putting new sealant on.
 
Oops completely missed page 2, if it's running down the drain channel from the gearbox then chances are the R380 output seal has gone and/or the oil seal collar is damaged. You can do both of those in situ if you remove the tbox but you'll need a bearing splitter to pull the collar out.
