SB 727 band lever help needed

So....
Pulled the valve body down and no strut lever for the front band. Apparently when he was removing fittings to use AN fittings for the lines to the cooler he removed that adjuster it fell down. Got it hooked up and adjusted and nothing again. Nothing forward, nothing reverse. Didn't perform any air checks, no idea what that is. So, what's next?
I'm Not Qualified to give advice on this. But if You dig on the web, or here, you can find the PSI of air needed to move things to see if they function correctly. I Know I've ran across the info before, just never done it....
