Hello all... I just purchased a 1982 Chevy Suburban 3/4 ton 4x4. I honestly don't know much about them. The one that I have is in pretty good shape. It has a newer GM Goodwrench 350. I would like to know how new though and dont know how to find out. Also I would like to find out what the tr4ansmission is and th transfer case.......if anyone knows or know how to find out please let me know...As far as I can tell right now the only thing wrong with it is that when I put it in park it will roll and click. Did some research and it seems that that it may be te parking pawl. Dunno.....Anyhoo...thank you for the look and help at this point would be greatful..
