Where is the auto transmission level plug on my Peugeot 207?

You shouldn't really NEED to know unless you have a leak or gears slipping from lack of fluid.It may well be sealed for life and need no maintenance,I've had autos for 30 years (and own a 206x11 year old for 5years) if it ain't broke don't fix it.

I don`t think it has one, you have to drain the g/box and fill with the correct amount of oil.
