car is leaking oil between engine and auto gearbox

[Fraz06]

Hey guys, My 318i auto is leaking oil from underneath so i had a look underneath the car and it appears that the car is leaking oil between the engine and automatic gearbox where the engine and box is bolted together, any idea's what is causing this and how to fix this? thanks in advance

Get a friend to put the gear in D while holding the brakes while you look under, if it leaks then i would guess converter oil seal, not hard to change, need to take down the auto tho.
