    Howdy fellas,

    I have been looking at diagrams and the transmission itself but haven't really found anything.
    Does the 13 speed road ranger have a vent?
    Similar to the drive axles? In my head it would have one but I haven't seen anything that looks to be a vent and the diagrams show nothing.
    It has been been pushing a bit of the fluid here and there from gaskets. Doesn't drip on the ground even but I like when my stuff doesn't leak any oil.
    Going to pressure wash it one more time and then start doing some gasket replacements.

    Thanks

    There is not a vent. I would assume the shift tower would be enough to prevent it from pressurizing itself.

    Thanks I assumed this was the answer but wanted to make sure I didn't somehow miss it.

    There is a breather on the top of the case short housing cover that can get clogged up and it will pressurize the case. Some rebuilders replace them with a 1/4 npt plug but it should be a breather.
