    Sorry other post won't work for some reason.. I am going to show my ignorance.. I just bought a second K5.. It as a 203 in it.. What does low loc and low mean.>?? Does low mean only the rear are engaged?? It does have the part time kit in it.. I am used to the 208..I feel stupid for asking..But I don't now..Thanks Dan

    Low is like an open differential. The power of the motor will go to the axle with least traction. Low Lock will lock the front and rear axle together so they spin at the same speed, just like 4 low in your 208. So if you put it in low with the hubs unlocked the truck won't move. This is because all the power will go to the front axle, and it is not locked in. So with a part time kit, you won't be able to use high or low. Only high lock and low lock. So to drive on the street it will need to be in high lock if the front hubs aren't locked in. ( I think I am right, if not someone let me know.)

    So if the hubs are locked in.. I can't just drive around in 2 wheel drive.. It will always be in 4 wheel drive unless I unlocked the front hubs?????

    well ya sort of . your high is like your high on a 4wd but the front tires dont spin at the same rate as the back ones this way it makes it easer to tern and you get better gass , your low and high locks mean hmm how can i say this ... well any loke spins the fron ties the same reat as the rear tiers. it is alot better for 4weel but if you get on the streel and you notice that you turn sharp and slow you will get kinda sort of slip with your back tiers and it you mite hear a knocking sound lock for 4weel no locks for street that is what you need to know , hoped i helped you out a bit more

    Hey gokartergo. Dont feel bad I swapped my 208 for a 203 and I still dont know what gear is what and I'm being dead serious. I guess because I dont get to play to often. I do know I have a part time kit and it doesnt loose power in any gear with or without the hubs locked. Oh and I did run around town without a rear driveshaft for about 2 weeks and I still didnt have power lose.

    the 203 has 5 positions...
    lo lock
    lo
    neutral
    high high lock

    lo lock and high lock means equal power goes to all four tires... front and rear...

    lo and high mean all wheel drive... but not all the time... power goes to the wheel with the least traction... so if you took your driveshaft out and tried to move it may go a few feet and then will try to spin the other shaft you pulled out and you wont move.
    If you lock your hubs in with it in "lock" then you are in 4x4 mode
    if you unlock your hubs in lo or high (not lock) you wont move to far...
    if you unlock your hubs in "lock" you will be in 2 wheel drive... but your front driveshaft is still turning.

    get it?
    if not just ask again I'll explain more... I put mine in high and pulled the front driveshaft... went to 20 mph and that was it... it realized there was no power up front so the 203 decided it needed to send power to the front non-existant driveshaft... i was stuck... 1/2 mile down my rode...

    I assume you have locking hubs on the front, or you would have said otherwise. I'm not sure how the part time kits work, but if it is regular full time 203, i think this is how it goes:

    Hi and Lo- t-case acts like an open diff. thus any free wheel will spin, front or back.
    Hi loc and Lo loc- t-case gives 50% to front and rear, like regular.

    With hubs unlocked, all the torque geos to the path of least resistance, i.e. front shaft. So...
    without a part time kit, and hubs unlocked, you need to keep the case in loc to go anywhere, and both shafts will spin. With the hubs locked, Hi and Lo (not loc) will act like full time case.

    Hope i got that right/it helped

    I have a 203 with part time kit, in my blaz low is rear wheels only even if the manual hubs are locked in, low lock is front and rear. Same goes with high range.

And while I don't pretend to be the smartest person around.. at least I can spell past a third grade education.. Grow up and listen to these people before you spout your mouth off.

    Just wondering, why would GM ever use this transfer case, i've often wondered this. Is there any advantage to the 203 over other transfer cases??

    I wish I could get rid of my 203, but time and $$ are issues...

    I think it was there first tries at full time four wheel drive.. Also from what I understand these were chain driven.. Not gear driven... I am learning a lot fast about these 203's.Dan
