Thanks Tate. I got it figure out now.
The front output has to be in neutral then shift the rear to HI, then shift the front to HI. Its preventing HI in one axle, LO in the other.
Does it have fluid in it? Did you just silicon it all together? It will prob be easier to take it apart and install a piece at a time.
Going to probably wait till after TCC to start putting it together
