Ok, I have the F25 box.
Now, when you look into the engine bay, the top of the gearbox, underneath the duct for alternator cooling, there is a small plastic plunger on a spring sticking vertically upwards from the box.
What is this for? is it some kind of pressure relief valve?
The reason I ask is I constantly have a little puddle of red fluid on the webbing on the gearbox in this area so I am wondering if I have a leak.
Its not power-steering fluid is the level in the P/S tank remains constant, so I reckon it may be gearbox oil.
Where is the level plug on this box? Haynes is rather vague on the subject.
I presume the box and fluid are "sealed for life" so the oil shouldnt need changed, but surely there is provision to check the level and top-up if necessary?
