    ok i have a 74 chevy blazer was full time 4wd-350-350tranny-203 t-case. My question is, did this ever have "2hi" on the t-case or is it only 4-lo,N,4hi?
    The shifter seems to stop at what would be 2-hi but if you put it in drive it acts like if it was in neutral. What is the deal? Do I have a big problem or is this the way it is??

    From the factory, the '203 does

    Lo Loc
    Lo
    N
    Hi
    Hi Loc

    or somesuch, right? (I'm too lazy to go out and look at mine at the moment :) )

    With the part-time conversion kit, that shift pattern changes to

    4Lo (front most)
    4Hi
    N
    2Hi
    2Lo

    I do believe.

    The locking hubs on the front axle are a good indicator that the t-case PROBABLY has the conversion inside, but not a guarantee.

    HTH.
