    Looks like you didn't research that there's 2 different cases, the normal case for 2WD models and the K case for 4wd. The cases themselves are identical if I remember correctly, but the output shaft on the 2WD model is a few inches longer and to swap the output shaft you have to tear the whole transmission apart as it's the last thing to come out of the case and the first to go back in.

    CORRECT 4L80E 4X4 TAILSHAFT

    You are correct I did not due my homework. I was happy to find a 96 80E that I screwed up.
    Bad winter and alot of trannies took it on the chin here in the midwest.
    This is the correct output shaft for your torque converter. Yep right near 3" differance. Now I
    suppose I could put a 4" extension on the back of the wrong one!!!!! No, I now have 2 to rebuild
    original is on the stand. Looking for suggestions on the kit??

    If you're going to break it down, you might as well do the whole rebuild kit and whatever upgrade parts are available. I'm not sure what all was upgraded by GM or the aftermarket as time went on, but one example may be the sun shell. That was a weak point on the 4L60E transmission. In terms of what brand and who to get it from, I don't know. Thankfully I've never needed to rebuild a transmission.

    Yes Crawdaddy, I agree with you should probably have all the updates. But first tranny since a standard three speed on a tree in a 62 Ford falcon. Hell I paid 50 bucks for the car. Put $20 kit into it and a 19.95 Earl Scheib special paint job special ment I got to pick from ten colors I believe instead of five. Beat the hell out of it put a clutch and sold it for hundred bucks.

    I don't think the sun gear is the bad part of 4L80E it may be if someone knows that please let me know if I could put back together thank you.

    I do like the truck but it does have 308,000 miles on it. And I think I need to refresh the bottom and I think the bearings are getting a little sloppy.

    Thanks for the come back see you

    I split your posts into a new thread since it had gotten too-far off-track for the original thread.
