Gearbox leaking from side.

[wishbone]

After giving someone else advice on RTV to fit sumps I found what looked like my newly fitted sump from Vince was leaking

However the leak is actually coming from a plug fitted into the side of the box. I thought I had a gearbox manual but cannot find it.

So my question - what is this thing it's leaking from and is it an easy repair ?

Thanks,
Rob.

Ho ho there's a seal missing there. Off to Toyota for a new one. Can't believe it has dropped out completely !
