mk 7 rwd 6 speed gearbox oil leak

[pjjohnthomas]

Hello boys.
Ford transit 140 p/s rwd 6 speed 57 plate.
I have just had a service on my transit, and the garage said they had to put nearly a litre of oil in the gearbox.
I did notice a very slight whine when i took it in but filling up the gearbox fixed the problem.
50 miles later i noticed most of the oil came back out, 100 miles later it started to whine again.
I topped up the oil with a small amount of oil to get back to the garage, they thought the first motion shaft seal had gone but after removing the gearbox the bell housing and clutch is dry as a bone.
The oil seems to be coming from the top of the gearbox and running down around the bell housing area.
The only thing there is the breather tube......
My question is have anyone experienced this problem before and have any idea how to fix this problem.

Fault diagnosed!!!!!!!
They have since found out that the gearbox was overfilled with the wrong oil, and was being forced out of the breather tube.
Silly mechanic filled up the gearbox to the filler plug level which in turn holds 5 litres of oil when it should hold 2.2 litres being a 140 p\s.
Still unsure if there is a level indicator plug on the gearbox, we just measured the right amount of oil.
If anyone has sure knowledge of a level indicator plug please post here for future reference.
