Any help would be appreciated.
I have a 2007 115cdi vito auto. Just had the gearbox oil changed simply because of a leak Which I thought was from the pan seal. Have now rechecked and it seems to be coming from what looks like a black rubber cap on the top of the gearbox at the front. Could anyone tell me what this is please. Thanks. NEWBIE.

 

Anyone tell me if this is a release valve or what it is. Thanks.

This is a picture of where I think the gearbox is leaking. Can anyone help who knows what it is?
