EWB555 Posted January 14, 2012 Share Posted January 14, 2012 So my transmission has 2 of these inversion valves bolted together on the side. The outer one was leaking air out the end of it, I believe its the exhaust, so I replaced it. Aired the truck up, backed it out, shut it off, no leaks, thought I was good to go, then today I pulled it in. and the new valve is doing the exact same thing. I would guess something is backfeeding through the valve causing it to leak.Also someone has color coded the airlines with zip ties, so I know I put the line back in the correct place (unless they coded them wrong previously) Quote Link to comment https://www.bigmacktrucks.com/topic/22664-12-speed-inversion-valve/ Share on other sites More sharing options...
