    The good old cast iron NP205 is the strongest. What are you running now for tranny and t-case?? This will determine what you can run with you curent tranny.

    I would assume a 205 since that's what the '80 blazer had. I doubt my K10 is any different.

    So my best bet is just to rebuild the t-case I have? Sounds good to me, hee hee. Thanks all! /forums/images/graemlins/thumb.gif

    Not always. If it's cast iron, ck to see if it has a fill plug and a drain plug. Only the 205 has the drain. If it has no drain, It's a 203. they used both.

    I know what should,but It's always good to make sure. A friend of mine, who's new to chevy trucks, has an 83 K10. He was trying to get parts for it and nothing would match up. His truck has a 203 T-Case, and a 12 bolt rear axel. It's always good to make sure!!

    It's almost impossible to shift at times, other times it's perfectly fine. The exterior looks okay, other than covered in dirt.

    Any thought at what could be causing that? I can only think it's maybe something internally in the t-case

    The 205 in my Bronco is sometimes hard to put in gear. I have learned that when it wont go in I would put it in first (manual) and move a forward a few inches and it would go. If you have an automatic make sure your in neutral only.

    If its an auto; trans in N, w/ the truck rolling, now shift, don't stop at N on the x-fer case. You can also mod the rails for 2 LO. Depdog did this and said his also shifts easier now. I was going to do the same but my 205 truck is parked right now.

    a-u-t-o-m-a-t-i-c???!!! What the hell is that?! /forums/images/graemlins/rotfl.gif Oh, you mean that tranny in my LUV!

    Nah this is a 4-speed. Hee hee, and from what it seems, I scared it straight with all this talk of replacing it. It's worked the best the last two days than it ever has since I bought it a month ago. /forums/images/graemlins/rolleyes.gif

    Really, I'm starting to think it's all that GM 10-bolt up front. All I've changed in the last couple days is new tires. Maybe the old tires were uneven and warping my front diff a bit, therefore causing the t-case to hate me? I was having a bad time with the lockers too with the old tires, and now they're also working great.

    I dunno. I need a d60 up front, though. I'm thinking that's my next big buy... well, after an acoustic bass guitar I've had my eye on for a while, hee hee.

    Then a d60! I'm tired of that GM 10-bolt and having to tear the hub apart every couple weeks to tighten everything back up since it all has the bad habit of wiggling lose since it's been damaged. /forums/images/graemlins/angryfire.gif

    Ah-well, what do I expect from a truck I got for $600? Hee hee.

    lockers and a 205 can easily load up the gears,
    apply pressure to the shifter and bump the clutch a few times in gear
    it is a feel thing you will learn
