Don't know for sure on your model, but many makes nowadays have a drain only and refill the correct volume of oil via a breather/filler on top of gearbox.
Not my favourite method as for peace of mind and in case of slight seal oil leaks you don't want to have to replace the entire contents.
Perhaps another Forum member can give more specif detail on your model.
The same year Panda 1.3 had a combined level filler plug on I think the front of the gear box
but though I have checked mine It was a year or so back and I cant remember exactly.
