ford focus gearbox oil change, were is the filler cap and drain plug?

[devpreet]

i have a 2002 ford focus 1.6 petrol and have had problems with the speed sensor (speedo droping out). managed to get that stupid little pin out with abit of grief, but when i pulled out the old sensor a load of gear oil came out with it. had a look about but didnt see a drian plug or level indicator.
any ideas??
by the way it is a manual gearbox and a standard uk model.
