    Ok
    please help me on this.
    i got the old hellbitch running in what is sure to be the first of many steps to get it like i want the firebreathing monster to be. :D
    i have the transfer case shifter all the way forward and the things runs SLOW.
    so i reckon it is in low.
    i would like some info on the pattern, correct way to shift from one range to the other and all the info i can get on the thing.
    btw, i believe it is an NP208. :1zhelp:

    '76 will have an NP203 stock:

    http://www.chuckschevytruckpages.com/drivetrains.html

    Without a part-time kit in the transfer case, it's

    Lo LOC (no front-to-rear diff) farthest forward towards the floor
    Lo (differential between front-and-back)
    N
    Hi
    Hi LOC / farthest back towards the driver


    With a part-time kit in the t-case, it's

    4 Lo
    2 Lo
    N
    2 Hi
    4 Hi

    Note that just cuz you have locking hubs does not mean you have a part-time kit.

    I only ever used 4LO (all the way forward) and 2HI (one click up from all the way back) when I had a 203, with the part-time kit.

    If it is a 208 that somebody has swapped in, it'll have four shift points, 2Hi up front and I forget the rest :haha:

    Ah, took me six months to figure out what the heck I had when I got my '74.

    Unusual to see one bone stock; most of the ones I've seen have the part time kit and locking hubs, as it was popular in the 70's and 80's to do this for mileage :rolleyes:

    Anyway, be careful with the Loc positions, as they will eat your tires if you drive on dry pavement that way. Great in low-traction situations though.

    I'm sure you can easily find the metal frame for the transfer case boot with the shift pattern, if you don't want to remember it. (Local junkyard, or a member here -- you can have mine for shipping costs :) )

    anything except bone stock is the norm here, for any 203 that are left around here, which are rare now,

    no one around here converts them, they just stick manual hubs on and thats it

    ppl dont realize that 203 are 4x4 only and not 2wd

    my neighbor wouldnt believe me his 79 k-10 is full 4x4 only, he just never looked at what the shift knob said,

    duh,,

    still has no clue, just liek billions of other ppl with a 203 rig


    good luck

    you would need to have the lever in a loc position with the hubs unlocked
