Ahh, I knew Paul Harvey would show up for "The rest of the story". I pulled the fill plug on the rear end. Everything was normal. However.......This truck was done by me 40 years ago. It was going to be a driver my two very young boys could learn on. It was my first truck. I went to swap meets for a few years and could not find a shop manual. There was no internet and I was a dummy. We were buying a house, raising two toddlers, starting and growing a business, and then going through a divorce. Needless to say, I was busy and distracted. All of my excuses out of the way, I never knew I had to fill the ball collar with trans fluid nor did I know how to shim the ball collar to seal everything. The truck got 85% done and then pushed aside for years until I gave it to my son in 2002. It got about 400 miles put on it and basically was run dry. Now, I have learned so much it is time to correct the past errors and omissions. I throw myself at the mercy of the community for such heinous sins.
