leversole Posted November 12, 2013 Share Posted November 12, 2013 Blew something out in my SelectAir valve (Mack 12 spd) this evening...made it home no problem, giant leak blowing out on the left hand side of the slot...still shifted to all positions, must be the supply....Does Mack sell a rebuild kit or do I just take it apart and replace whatever looks broke?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/33479-selectair-valve/ Share on other sites More sharing options...
