Ant_mant Posted July 26, 2019 Share Posted July 26, 2019 88 MJ 4.0 BA10 Trans Can anyone clue me into this Air Breather Junction above my starter? One runs down and I think is supposed to connect to the BA10 transmission as a breather line. Do you know where it hooks in? Also can you tell me what the other 3 lines are for? Weren't run to anything when i bought it. Thanks! This truck has soooo many air and vacuum lines. Where does one begin.. Thanks, Ant Link to comment Share on other sites More sharing options...
87MJTIM Posted July 26, 2019 Share Posted July 26, 2019 One connects to the transmission, the other goes to the transfer case (if you have 4wd). Link to comment Share on other sites More sharing options...
Ant_mant Posted July 26, 2019 Author Share Posted July 26, 2019 I do have 4wd. is there like a nipple that the line goes over? I did not see any when I was under there earlier today. I would like to hook them back up obviosly to keep dirt and moisture from getting in. I just changed the fluid and it looked to have a little water in it Link to comment Share on other sites More sharing options...
