w126 300SE gearbox leaking and oil level

[spacemoc]

hello all,

I had a post about few weeks about small leaking from my gearbox, I have just checked the gearbox oil when the engine is off and level is okay, but when I trun on engine the level is way below the limit. I think so we need to check gearbox oil when engine is running, am I right. Do I have to top up? Leaking is very small like a 1 drop per 4 hours.
