    ok guys.. help me out here.. my neighbor has a 1989, i think 3/4 ton chevrolet truck, 4wd 350, auto(700r4, right?).. he was on his way to mexico when it "broke" as they explain it, so i had to drag it through his yard for him when the little mazda they towed it from the interstate to his house with got stuck in their yard....anyways..

    when you put it in park position, it just grinds.. im thinking something internal to the transmission is screwed up.. whats your opinions? im gonna try and look at it this weekend and see if i cant "drive" it.. might be able to buy it cheap and need some info.. thanks..

    it was probably the t case that "broke". with the tcase in neutral and put it in park, it grinds because nothing is stoping the tranny from spinning.

    big83chevy4x4 is corect, sounds like the transfercase. In a rear wheel drive car you have the foot on the brake when you put it in park, but if you didn't the parking pawl in the transmission makes a god awful racket until it stops. They need to look at the tranfercase.To verify this turn off the engine and put it in park, truck may still move when pushed or pulled. If he's lucky it may just be the linkage got popped out of gear or something, mine did that once wheeling. /forums/images/graemlins/k5.gif

    I'd try pulling the t-case into 4-lo. See if it will move then, thus stopping the grinding.

    I have had several 208 and 241's do exactly this. Low range has always worked for me until I could get off the road or back home going slowly.

    My .02,
    John

    Edit: Make sure they put it in low-range with the engine off. /forums/images/graemlins/wink.gif
