    What is what on the 203? L loc 4low?
    L 2low?
    N nuetral of course
    H 2high?
    H loc 4high?

    I can't seem to get the front wheels to pull. I can get it in and out of high and low, but can't seem to get the front end to pull. Any help would be appreciated!

    If your truck is converted to part time then yes that is the correct shift pattern. If it is unconverted (no locking hubs) then the L and H is full time and the "Loc" Locks the center diff to give a true 50/50 power to both axles. My 203's always seem to shft better with the truck rolling. at about 5-10 mph with tranny in N try shifting it. Sitting still it really seems to fight but it pops right in with the truck rolling.

    thanks! it hasn't been converted. I'm saving my money for a 700r/208 buildup that will replace the 350/203 that is currently in my blazer now!

    the 203 is much stronger than the 208. A stock TH350 is stonger than most modified 700R4's If you plan on being real rough on the truck then stay with what you got. You can buy a whole lot of gas with the cash your going to spend to gain 1.5 mpg.

    i'm building the 78 with a 400smb/700r/208/dana44/14ff/6" suspension/35" mudders for a daily driver. I will be putting the 350/350/203/dana44/12bolt/no lift/major fender triming and large tires (don't know size yet), on a 75 full top for trail and mud use!
