    I have 2 203's. One was on a tranny I used to replace one on my truck. I was told it was stuck in 4hi. The other I pulled off my truck where it would go into anythingbut neutral. We prybarred it into 4hi, I drove it around the block, put it 4lo to go up a small hill into my yard, no problem... until I went to pull it back into 4hi. It wouldn't go. It was full-time. The former I can't be sure, I never used it.
    What I would like to know is what are the problems with each and if they are separate problems, can one be fixed with parts from the other.. If so can the range box be salvaged and if not can a range box be salvaged. Either way, I want a range box for a Doubler. That sounds so cool, I gotta get one. Sometime.
    I don't know a lot about t-cases but I'm trying to learn.

    Check in a Chilton's or Haynes manual and adjust the shifter to specs. Then see if ya still got problems.
