I have a 98 2500 with the 5 speed in it. During my last oil change i noticed it was leaking a bit. Was wondering if there is a breather on these transmisions and if anyone else has had the same problem. Not exactly sure why it is leaking, any help would be appreciated.

I took out my NVG4500 and now it leaks out of the top cover. I think there is a breather hose.
