    Does your blazer throw you back in the seat when you punch it on the street/freeway? My dad's 80 Jimmy (th350 np205) use to do that, It got up to speed fast and threw you in the seat when it shifted and was awesome. Then the tranny was rebuilt a few years ago after it started slipping, it took the mechanic a couple of times to fix it and he told my dad he put in transmission fluid in the transfer case. Then I just read the 4wd fluid post and some of you said the np205 takes gear oil. Also it makes a clunking noise when we try to drive it in 4wd and takes a long time for it to shift. Is the tranny/ transfer case shot?

    Is the clunk just when it goes into gear or a constant clunk that gets faster when you speed up? If its one big clunk than it could be the u-joints, spider gears, ring and pinion, pinion bearing, or the hub assembly. A steady clunk would also be a u-joint.

    I just did a '79 K10 Bonanza for my uncle that had some bad clunking. The splines on the axles and side spider gears were worn causing too much free play in the rear. In the front, the splines on the rotor for the hub assembly were worn razor sharp and allowed too much movement.
