The 1988 Suburban Part 4. Will it turn over or will it start? What else did I forget to do last summer when I stopped working on it? | Big Trucks Low Bucks

The 1988 Suburban Part 10. After pulling the pan and seeing (and smelling) the condition of the fluid with all the material in it, I know it's not worth digging into it further. The transmission is just bad and only has 1st and reverse left. So, I'm just putting it back together enough it will still at least drive with first and reverse this weekend until I do a transmission swap later. | Big Trucks Low Bucks
