I was diving my buddies plow truck the other day, Its an 85 K20 with a 454, sm465,and the np208, i got to spinning on some muck so i stopped the tires from spinning, and put it in low range. I let the clutch out and heard this awful smashing noise, i got out, looked under it, and all seemed good, i got back in and tried to move it again and the same noise happened. Got out and there were big chunks of aluminum on the ground and a gush of ATF. Oh Fuc. i crawl under it and the planataries in the low range side let go. anyone else ever see this before? I have a 208 from a th400 im gonna slam in this weekend but i dont really want this to happen again.
