    Did it hiss like mad when you split the gears? That spring is what puts pressure on the rubber gaskets to seal them when you split gears.

    Well the splitter still isn't perfect the way it should be. But there is a small air leak which quickly goes away - on it's own - it isn't instant - but it functions.

    I think that you have something inside the transmission that is stuck or broken, I believe that it will be inside the back box.

    Sounds like maybe the inner shift crapped out on him. I know a company trk. I drove years ago went out and I was stuck in low. It's in the back box. Right now I can not think of the proper name of it right now.

    Sounds like a synchronizer problem in the back box, does it grind at all while range shifting?
