I think there might be leakage between the t case and trans, I am hoping that gear lube is the way to go though because I think that t case makes too much noise sometimes. I need to know soon because the season of the hunt is near and the fluid needs to be done, I don't think my dad ever changed it and he has had it since 91. On a different note what suggestions are there on a complete exhaust system? I'm looking to a easy to install and quite dual system.
