    I have a 1978 Chevy K-10 with a np203 transfer case. It always sticks in 4-Hi. If I try to put it in any other gear, it either doesn't engage or pops out as soon as I move. I am guessing the t-case needs to be pulled apart, and possibly rebuilt.
    Does it just need to be rebuilt, or is it worse? If it needs to be rebuilt, how much does this job usually run? Thanks in advance.

    Check the shifter for alignment on the shift rod.

    At the risk of sounding really stupid, where would that be? Do you have any pictures?

    Loook under your rig by the Xfer case the 2 rods should have a hole in them. place the shifter into Neutral then try place a drill bit into the holes at the same time.If the bit doesn't fit through both at the same time, adjust the linkage nuts till the holes are lined up perfectly so the bit slides through both rods!
